Subject Area
Aerial imagery is a core base of many mapping related projects. With the increase in the use of Unmanned Aerial Vehicles (UAVs), lower cost satellites and more generally openly licensed imagery, there is a need for one place to search and access that imagery. This is a big undertaking, and certainly can't be left in the hands of a single company or organization. OpenAerialMap (OAM) addresses these issues with transparency and open access. A project for 10 years, OAM has been relaunched as of 2014. Now under active development, a dedicated open-source community is emerging. This presentation will cover the following topics: * The general architecture of OAM * How to contribute data directly to the system or by hosting your own node * The future road map and how volunteers can contribute

thank you I'm just introduced myself I work for the kid Astor Foundation of we help communities document their property rights primarily in places where people don't have formal want lander castrol source systems but we are interest in open aerial map because part of that process is you need imagery to to enhance a mapping so I'm going to start off with a
little bit of history and background on open aerial map but the idea of creating a commons for sharing free and open imagery came about around 2006 there were people that were beginning to fly UAV is in 2 rounds but it was really mostly just an idea at that point but but then in thousand 10 the result large earthquake in Haiti and a lot of imagery became readily available for example the World Bank imagery with 3 aircraft and made them available under an open license but there wasn't really a good platform to share that to process that tin index at and a lot of technologists were just doing were spending large amounts of time processing in making that imagery available so this idea of open aerial not once again became very important and and then there's another major disasters as well but were also beginning to see more imagery being available just because there's more there's more commercial satellites and agencies governments are launching satellites and providing the data for free under open licenses as well as you may be usage but
we and and it end at as we see this a lot of technical experts are able to access that imagery but the average person there's not really a way to do that and so that's really what trying to them
so open aerial map was rebooted last year at by the Humanitarian OpenStreetMap team 1 thing I should have prefaced is until April of this year I was executive director of the Humanitarian OpenStreetMap team so I was involved in an a P in obtaining a grant from the humanitarian Innovation Fund to build out a pilot of open aerial map and that one-year grant is ending in October of next month of this year but
in addition to the heart the mentoring of you that team there's also quite a few organizations involved in the open air can community of we have we've come together because people were working on their own imagery indexing tools as well as processing tools and we thought why don't we work together 1 of the beauties of open source rather than containing think continuing to do things on our own and this is all powered by the Open
imagery network so the open imagery network is the distributed index of open imagery but it actually is just I get help repository so if you had imagery and you had posted somewhere you can go register and get have your your bucket of imagery and then it it would be registered and the open imagery network the idea that index is then people can build tools on top of it so it's essentially just pointing toward the imagery is and is a very lightweight metadata from standard that's a component of that and so the way of the open imagery network and open aerial map work together is that open aerial map is the 1st implementation and up of imagery tools using the open imagery network it's a little confusing but the images of an imagery that work is the actual imagery and open aerial map is the tools to index and processing use sedimentary
that I forgot to check in with open air lacking so I'm not sure if or out beta yet open Errol not spent data for the past couple months so you can try grinders you're all that the dead . open aerial map that word that is worried that may reside at the moment what were switching over added beta sometime in the next week or so and you'll see up there there is some is not a ton of imagery at but there's certainly I that imagery for an assortment of area the whole world is not covered on primarily at a lot of imagery from related to work the Humanitarian OpenStreetMap team is doing or related to disasters that happened where there's been imagery really so the symmetry of the Paul for example and is also imagery of Tanzania taken by UAB after through World Bank project this year the so in building
at open Errol that we were looking at 2 major use cases the 1st is those users that are not highly Tech of technical of need defining use imagery and as other use cases were those people who actually want to share with sharing imagery is horrid and you've gigs Indians of data and and people maybe don't have a server that hosted on for example so we wanted to give them somewhere that they can upload it because when people want open up the data needs to be a way to say 0 thank you very much and then help make it useful 9 here these groups are happened highly technical remote sensing specialists that and the 1 I think particularly interesting is the users with imagery that need upload and share 100 and 1 user group in there is the is hobbyists drone pilots who go take imagery and then this is not really a commercial value they'd like to share it but then I have to take the time if it's difficult to share it so were giving them a place where they can upload and and so this is a diagram
of how 1 might it imagery of 2 situations that we think about especially open-reel maps primarily started offer humanitarian and disaster response is not the only use case but it's the 1st use case scenarios we focus on both online and offline and so would provide web trials for example that you can use online but if you actually need to download the imagery and take it with you that's an option as well so these 3 major components
to open aerial map so there is a web interface browser which is what you see if you had open-air ailab . org but there's also a catalog which is warming API of that and that and then there's also a server component that does processing primarily a can take raw imagery and turn it into tiles and these are all separate our projects with and get out of that you could contribute to then there is another at
were starting to build a bit of a ecosystem above ground of an aerial map there's also q just plugin that allows you tunable search an imagery downloaded it as well as uploaded this is developed through a program called every at Ricci I used to be called the no Outreach Program for Women it is very similar to Google Summer of Code and it's paid it's a paid internship where you work with an open source project I given to add women and other minority groups in open source so 1 of the projects that hot sponsored this year was building of a cue just like I'm in the of repository is is right there and then I'm going to show a couple screenshots so
that it essentially allows you to the book maybe it's a bit hard to see that this buttons for searching and browsing as well as downloading imagery I it's meant to be sort of the wizard be easy to use
of and and here is where you if you're uploading data on you can see the the j signed on metadata requirements as well as you can pick where you're uploading it to i currently we only support Amazon Web Services for the upload buckets but you can and in this case and they're just using a test 1 but the Humanitarian OpenStreetMap team provides 1 because we we want people to share imagery but you could also use this with your own bucket of imagery as well so the big reason I'm here
of it is also to help recruit there's lots of ways to get involved and there is quite a few people cutting but but of course pull requests zeros welcome but testers would be great doing community outreach so I am in determining the open air map community right now documentation and another 1 that I don't see a lot of projects asking for help help with uh so much these days is legal help and the reason I mention that is really imagery under an open license so sometimes legal assistance could help discuss with companies how they might do that but you probably don't even need to be a lawyer more an Open Data advocate could certainly help
in the final and you have imagery but were continuing to build house a repository of open imagery like I said there's and there's not a ton there now but the rope the wall continue to be more and more added so if you can help contribute allowing other people use your inventory that would be great and so do I contribute
imagery there's a couple different ways about 1 you get a get have any open imagery network organization there is a repository there that walks you through how to register and you you essentially are just adding yourself to you're Amazon S 3 bucket the bucket of imagery you're adding it to this and then it allows anyone who would want to go and crawl your imagery to older do that and this is another way of doing it you can simply just upload through open aerial map and in this case what that does is your contributing a imagery the Humanitarian OpenStreetMap Team bucket so if you don't wanna mess around with doing at Amazon account for sorry you have the time or any other reason you can just contributed directly there as well this is still interesting and with the released more formally in the next couple weeks and so if you want to get
involved in an open area not in general there's quite a few get have repositories of the various pieces of the project initiated this 1 it's the main 1 little point you in the right direction I We also we also meet
I'm weekly on data so if you go to the idea of the that you have your neural there's a button that says during gitter it's just a chat room where you can log in with your get have account very easy to use so there's wide meetings and at 1800 GMT for about an hour every Thursday we usually have about 5 to 10 different people participated and you know is if it is that times unfriendly for years you can always them read the archives as well we also have a mailing list of a route you can join FIR offline discussion there as well is a few things were thinking about the
future out 1 of the big things is right now were only integrating with Amazon but we want be use other cloud-based systems as well and as well as having offline appliance so 1 of our major use cases for this was after a disaster people needing imagery and so they can it's great if you have a ton of imagery available online but if people can access but because they have variable bandwidth or no band with due to a disaster it doesn't do much help so we want to build and deploy this on a computer where it could go to a disaster area and imagine someone is flying drone to take pictures of it and you could upload it directly on your local computer in your local area network and then actually have data process it make it available so that's
open-reel now are there any questions tha the some listen over there you must what I have at the moment or certain doing best case it is an area of I think the Tyler will handle converting over 2 different reference systems but to be honest I I think you can define them in the metadata but because of you go but to be honest I can't remember exactly how a dealing with them any other questions over the this you the the what the the the problem is as you the so so the moment were not creating a mosaic it's more of them so if you go look at the the the catalog you can see what imagery is available at overlaps and you can pick which you there you download is a for years of but we're not trying to create a mosaic right now the idea would be if someone wanted to build their own we have a source so we have an index go book and find the best sources for right this of the as yeah you can do you could do a combined set but i'll in most of the case that the major use case right now is the needing to load a tiles that set to 0 edit and OpenStreetMap basically so you probably a editing a small area and you just need that 1 image right the right on any other questions it's got a place for people to go on sometimes the uh the real big need for image reason in countries that don't want you to publish and we have opened in history of the 2 view what what kind of scenarios to discipline well is OpenStreetMap runs into the same problems of as a board member the OpenStreetMap Foundation I see a lot of those e-mails end I think the best honestly don't usually a matter of having a policy of and the you're right it's sort of a political flesh legal question depending on the servers are as well and I don't think we really thought a lot about it to be honest to so far have but yes definitely that will potentially be ownership are there questions from the floor the in the bag along sorry we we were running ahead of but if if anyone wants to talk to me afterward we can definitely yeah the fast food on a 1 customer so far and so do you recommend and in specific kind of licensing for of inventories so doesn't get point and something I should cover with the open imagery network we're doing 1 license which is lasting ideal best best case scenario and were doing a Creative Commons Attribution License and with open aerial map itself it uses the open imagery network but it also uses all the imagery have under other other licenses as well because we realize that if we're negotiating for open imagery we can say hey you should use this license River Dotty open then that that would be difficult to to try to change that over the I and I do love chickens at the so I've player pelletise for those arriving at this point to this as an because we are just about to close this the work session we have already had all wonderful present in in In ahead of time actually the complete that at that talks and actually I must say that this is something that proves that the capability of open source and open data to actually help facilitate development in the world and also even say people's lives and in the end so that the summary vary in them so portable initiative and so basically it do you have no any questions for them for any of the speakers at this time so about all scurry mapping platform about aerial unitary or about them them to processing tool for you take so we have heard the 3 great presentations and and very by riot topics of different kinds of projects and I and I think this also tells about the diversity of open source we have we are engage in so many kind of activities this is a good example of this session is a good example of that in case there are no further questions I will ask you to report to the retention test and before I do go i'd like to it is something it is something to take with you back from back from solving that it is actually a field a box of penis microns so so be careful if you have never tasted and if you want all stickers on the handout them for you no thank you very much but it but as a person so the and the the the the only the the and the and that and not long and they say in the but the but but but theory of abide by popular demand that belong in the uh he's going to reprise you talk because we've got the
world to use the so on without any further open aerial map but per 1 again you know what the this is the only thing you with that this is this is again there's a couple people have been involved there longer than I have you have now come the room as all as so open allowed as a distributed environment for searching and hosting free imagery and I want to go back a bit in the
history in the background I think this idea in 2006 I said that very authoritatively in the 1st row version of the doctor's Jeff Johnson wasn't in the room to correct me of N so it started this idea of the people were flying UAV is restrained produce imagery in the question was what you do with that imagery if you wanna have it under an open license the and so this idea of Errol that became mostly an idea at that point I and then 2010 there is the the large earthquake that happened in Haiti and a ton imagery became available at the there is a very detailed 68 centimeter imagery of the earthquake affected area that the world bank flu and then released under a permissive license and then there was a some of the satellite companies and just a lot of imagery and you were staying up all nite to process it to make it available and that in a pretty manual process and it was all going on some telecine servers that was sort of the since are the wild west of it imagery services and end the question then was can we make this easier on herself essentially and then there are quite a few other large scale disasters were about imagery was available but still not an open ear Latin really exist but there is a rate that little bit of funding from map quest to build it out but it is mostly a prototype at that point I and so inventories
continued to be available under more and more open licenses and so there's no need for open Errol amount has become become greater but there were really focused on your average web browser user were not focused necessarily a remote sensing specialists because they can can go find the free imagery at but let's even if you go find image really don't know how to use it that's not real helpful so were really focused on the non-expert
so the open Yale not was rebooted last year by the Humanitarian OpenStreetMap team and through the through grant funding from the humanitarian Innovation Fund and I was at the Unitarian of about human this happened and I was involved in obtaining this grant funding essentially of I left hot in April of this year I'm still up here waving the Open aerial not flag because my role at the could ask the foundation is were building open-source tools to help communities document their land rights turns out you need imagery for that as well and and so open L. not started vary with focused on disasters and humanitarian use but there's other groups like myself that could after who who needed as well on a very interested of the this is
sort of the main OEM community at the moment arm with the grant funding from the Mediterranean aviation find of a few these groups have been involved in and actually building things out and we've also been working with open drawn up by uh Stephen M. is around the conference I believe giving a talk on this tomorrow of this uh open actually does all the processing see end up with a nice GeoTiff which you could then put in open-reel maps are working closely together at so this is all powered by the Open
imagery network so we're designing open aerial maps the question then be was what is it it's been talked about since 2006 so it means a lot of different things to different people and we wanted to create the open imagery network which is actually a network of the open imagery essentially the get hub repository where you can go register your bucket of imagery at the said G adjacent metadata standard that goes with that you register bucket of imagery there and then someone could go crawl so open aerial map is 1 of the 1st implementations of software using the open inventory network so in
check between giving this talk about the 1st time in the 2nd to see if this is life we're still there is such a release it at a beta is debated open-air left out or Intel but maybe it's still and so what we're leaving data sometime this week I don't know the like I said the flip the switch I should check before my but you know there and see how the catalog works I'm in actually use open map so and that
focused on the 2 these 2 main use cases users of imagery the need to find and use imagery this could be a humanitarian worker on this could be a group doing community mapping and then those users that have imagery that 1 upload and share it a lot of those users are Imagen your hobbyist run pilot or professional developed for that matter who's paid fly area and then they're allowed to release the imagery under open license they don't take the time to figure out how to share it so we're trying to make it really easy so we said thank you for your contribution
and this is some a diagram of those use cases and a lot of our use cases are really focused on OpenStreetMap right now but how can you get imagery and download it into Josser more use of a stream out of work to end it but also those other use cases where if you just essentially imagery tiles for your application of both online and offline were important to us so that you can always download the raw imagery answer you could take that with you are in the human use cases for example you don't necessarily have enough bandwidth to be accessing imagery but you can imagine downloading that undue you computer prior to deploying to disaster area and then using it there this 3 major
components so there's a browser which is what you'd see it open aerial map . work is a catalog which is essentially API and then there's a server of the Dow's processing for example tiling we also have a you just
plug at I like to pitch the q just like in a little bit of 1 of the main reasons as it was developed through the out reach you program which is a program through the Software Freedom Conservancy which allows of which can't underrepresented groups involved in open source it workable works very similar to Google Summer of Code and that's a 12 week paid internships of an but it can be doing anything in open source to be marketing documentation coding at so the little wider and it runs twice a year so it's also hemisphere Southern Hemisphere friendly as well which is 1 of the big complaints sometimes about you and this is the 1st desktop tool for away and we're hoping that other software will begin to integrate with that as well so it's a pretty typical
he just plug in you know search for imagery of you can upload your imagery and then you do some basic editing of your settings as well so hopefully
you're all here because you want help and there's lots of different ways to help I put coding at the top that to be honest with some of these other ones that would be really great and community outreach is something more it could really use help who want people to share imagery so just asking a lot of times is a good way to get that I documentation 0 is important of as well as legal help and that's part of if groups do 1 open the imagery what's it mean to release your imagery under a Creative Commons Attribution License for example fairly typical Open Data problems and do you have a major looking for
contributors in that way as well so 1 of
the 1 of the ways to get involved on ensuring imagery is you know to get had that on open imagery network and if you're willing to host your own imagery you can go register the bucket of imagery there of and what this does is it's just essentially a text index were someone can then crawl all the imagery bucket index them pictures or how a search engine works and then build tools on top of it open aerial map for example being 1 of those tools the not the greatest screenshot of taken but you can also upload out so the mentoring OpenStreetMap teams providing at and has 3 Amazon bucket where you can upload your imagery and it goes into pots bucket in this case I I I would envision this use case being more like nuclear droning what 1 image to upload the yet bucket use case would be you have a ton of imagery that you wanna share but you also get in touch with us as well if you go look through the openEHR allow the get out tickets as people who have imagery of open tickets and after assistance as well and so this is
sort of a pointer project and I feel like these days a lot of open source projects in gets a bit confusing genome with 10 get have repositories for essentially 1 web applications so this is your your starting place
the so if you want back to the community we have weekly meanings at 1800 GMT we meet on getter you're not familiar with getter it's finally got piracy on basically if you go to the open air let get have pay um page there's a big button this is joined data if you click on it the angular and we've found that a little bit easier as far barrier to entry dated non-technical people involved in essentially but can also join a mailing lists there's open-air map google group so there's a couple of
things the matter future out right now it's heavily dependent on S 3 we wanna make it deployable integratable with other Cloud systems as well to give some options as well as have offline appliances the offline plants scenario it is but primarily focused on humanitarian response I'm sure there's other use cases where more and more UAB the flown after a disaster now but then that imagery even tho is that useful these days people here can't get off the ground to the internet so that they can you processing because there's no connectivity I am for people might be really good at finding is that they art so good at doing anything with the pictures what they have so the top 1 appliance someone would build a take it with them to a humanitarian crisis fly the imagery but on the appliance utile index that they could use it on their own network is the idea behind this not not requiring Internet access it's easy to forget I think sometimes that In an axis still is definitely a problem I'm sure it will be forever but we can still save lives with this use case any questions
that the yes so we have I want to call did you have to be Robert was so we want you but the open drawn that project is there creating an open-source toolchain to do that reading the you take the pictures up the drone and then ending up at at geotech which is why we're working with them who were not focused on that at all were inserted in the best case scenario we're giving us a GeoTiff Aaron what's the nature and the searching mass of the metadata associated with any of these I'm in what what what metadata properties is trying to capture what's the minimum viable dataset yeah I think it's actually pretty lightweight I'm it's there's like 7 7 or 8 at tributes I'm from drying of length and what they are
but I can just pull it up the but it 1 an actually in I'm in the wrong place so this is too easy on let's see for what yeah you yes so there's no gatekeeper right now I'm originally in where discussing it in it is getting really complicated and the they were were using the model of anyone can contribute I suspect what'll happen is say in a perfect scenario that we have so much imagery that it's hard to figure out where you where you wanna use that the decision reading an enduring but problem problem preferred providers or something I would I could see at some point so to appearance question so this is this is the metadata you see there's not a lot it's basically where is it a picture of fuel details about the actual imagery and some contact information just the can you he explained more like they're sexually train open imagery network in Europe on particular interest in like the policy side so on several different projects work on we know acquire imagery to be nice to have some like standard legal language to stick in these contracts with the when we purchase it so that it's you know it can be open the mean like to the policy says less about the yeah so by and this is what I think's going to happen is I think Bill and of being an open imagery network Foundation at some point to support that I'm when I don't know because the state things needed like that but that the technical problems they're sorta coming together on their own but the policy is actually the main miniature the so yeah and I really think that that advocacy and and that template languages what's going to really be key to change that and I think in organizations probably gonna have to support the support that have and you know the humanitarian opportunity of a supporting this as it is now but that's a really specific use case an organization with a specific mission so I suspect it'll end up as it something at some point tha the we have found of but poses a major from the state maybe pain trapped of the and now also generates the lacks energy or the for that's the an integer you want to share with us as to shall all vitamin but potentially with Landsat I I I suspect at least Landsat 8 which is already posted on an S 3 bucket ideally we'd wanna just point to that bucket basically am but if there's other imagery that's not conveniently stored like that we would definitely be interested but at so by means so you want to move and this way also opened could eat original images not processed images yeah so we want of raw image Regio tests all yes so for this we so we just focusing on visible right now and was a pretty common questions I so I suspect that could change the it was a matter you have to start somewhere tha of to be honest I don't know I haven't seen if I haven't been as involved in this project as I was when I worked for hot of and I not responsible for the Amazon FIL anymore that sort of stuff so I'm not sure you it that that's true there is actually so the moment there's only 2 buckets is is more I was thinking about the majority of it is in hot bucket of you could figure out if you want bucket you you could figure it out absent is only 2 it would be easy right now Aaron and maybe it's too soon that is thought about how the data gets replicated so that it's more distance single bucket the yeah we haven't really worked on that but yeah definitely the offline use case step only means that there's plenty of others as well fact thanks everyone who but this
