right well yes so step and so here in this room you're looking for data and and I'm here to introduce a site called you load that a word and which should help you find that data and a little
bit an introduction my name's keith that I met at Cornell University and in Ithaca New York and elsewhere thank you sure just pretend come in and also like grants electronic
1 l and I'm not of i t developer although I sort of this pseudo part-time IT theoretically at 1 point and said little tech products on the side of the main core of our work is as labor into looking for data of people use after help people troubleshoot software on all geospatial related
and so you're faster G and yeah which is open source software and but I'm here to talk about
data there was another slide it disappeared and because with all those great open source software you can do a whole lot of their data otherwise you map looks pretty much like this without the
data so wisely later on so let's talk
about data the others all right of data out there
on the comes from different sources at different levels of government hierarchies on regional projects international NGO this comes from hi cameras quadcopters paper plane cameras where we have so there's a lot of
data out there which makes it really hard
to find the specific type of data on that you're looking for so if you google
search or just plain GIS data no other qualifiers and I just updated this is because of this white 63 million for some reason last week is like 189 million so I don't know what happened all idea they just disappeared often and they read the recount I don't know whether the so that's a lot of results and is not sort of give something and browse through the only thing you connect to get to the end of the day this and so this is a problem but some
people may be but not necessarily for everyone
and local governments typically have all their own
data in their own systems they don't need of searching for the word is they have an to answer that's not really an issue
and experienced researchers already wonder where they get the data they need to process and analyze so for those folks is not so much an issue but what about the rest of us and who
is the rest of us everyone in this room and the
students who are just learning where to find it in a given that an introductory tutorial and you provided data for them and then all of a sudden in the real world they're doing their assignments vesicle finding that is very hard for 1st and this also
researches on who might be exploring a topic who might be new approach to a particular feeling don't know where yet to find that sort of data Almeda's journalist who might be reporting on a news story they need to track data down map makers of course
demographers during adverse that demographic data and civic activists who wear
watches burgers treasure hunters
deep-sea divers wilderness explorers
napping cat matters I heard you get extra points if you sure can you as get
point of view on a great big you presentations at 2 . 1 can accreditation beckons IT specialists
on farmers market bikeability analysts they need data for where those roads or by grouts the farmers markets and they might have a would find data so we might help so there's lot people looking for
data out there man and is
anyone who's trying to learn more about the world and map it to analyzes spatially they need you spatial data
so how about 63 million results for you google search it does relevance ranking if you hadn't had a termite Portland the beach termite land cover you you'll get lesson 63 million but still had a lot of results and on it's relevance-ranked literally means but you really a expect to find we want at the very top every time probably not so so the mass as my question is
who is going to organize this mass and what I would propose you being a librarian and the
Lagrangian organizers were they can on the began to and you might be thinking yourself librarians are those the people who
know work with books and people this is actually the a few the vibrant centers of model after but the uh the shooting library much in Nancy Pearl but action figures show she migrant and you can buy the on it was and so on so there's is
met that why branches people and maybe we do we're trying to concentrate on from from the data and but in reality and librarians said this might spread a little a different band and they look more like
this so this notice about books anymore and what is best in life to shift the noisy this even judging how and so in
reality librarians strange to conquer the chaos of the world by collecting it and maybe eventually were and and I say eventually because this sort of the
so this is the secret library reveal here and there are other library room so be careful they will defend me they have sworn and sacred of the you
so as a venture because I've sort of been working on this dual of project for 7 years and which is a pretty long time i've been some i backburner I work on it we have a lot of time and to 7 years ago
that you 7 0 using a cycle delicious misspelled it like that intuitive like that better or worse and as bookmarking things and a lot of people bookmarking is other this is great I can keep track of certain people who were also bookmarking geospatial data and aggregated all that maybe make a use the API to develop the site where you can filtering browsing and search across all these bookmarks so that's on a great but on delicious has changed over the years and are no longer using it on a few years ago I had enough and I the central my own sort of
thing and then eventually now here in 2014 is module load word and so what is the dual of this so
1st I I guess I should explain the name for so it's really hard to come up with a good name on not low-dimensional leaflet and it those acceptably name and it had been using only 7 letters right so this is only 7 matters but on and if you were can misspell LOAD and you may not know exactly what's referred so
the name comes from people look for the model of geospatial data that has been have a better name please feel free to suggest and it's a minimum
viable product so it's not trying to do everything in the world it has 1 goal and its the treasure it's best to do that on it
is extremely lightweight metadata now to categorized as can help you find geospatial web sites
and so the glorify bookmarks nite so XML metadata and a very light weight
and the interface is actually mapless there's no map the it's not like this can Annapolis but more
of a text-only interface because that's the minimum viable thing so what are the ideas that you can search you
can browse you can filter from all these different
data sources primarily by these 3 things so the place as the location that the topic deserved roughly isotopic so I think a split land cover of whatever else was punched in the and by more general freeform tags on the give more so specificity then the topic so now a little demo
here and per cent website of rulers enabling with that so here's dual load on in
its general incarnation on on the left you
can see that there are the different facets of place a topic and tag and I can click on any of these kinds of I'm interested in a particular place and so Pakistan for example right now
there's only only only 6 out websites in hearing the data for that and there's probably others and I'll we talk about having things later on the other thing you can do it is I
can say elevation data I can combine these sorts of
things so elevation and I'm actually use it in Elysian data here in the United States
on so here I get all these results and you can you know FIL things down further and further and got a free-form searches Whittle search these descriptions as well the titles and everything such is really a lightweight bookmark specific for geospatial I of this and
the fact of but you can also
edit so there's an editing interface that I'm a pronounced as to me but I will talk about that in just a moment and so with any now
obviously need an editor to go in new things
and there's also bookmarklet and they'd his jacket of your browser toolbar are and you have editing privileges used when you're on a website of stew spatially click it it opened up editing informing you can provide little information that I the
bookmark alignment we grab the title in URL if you selected textual with that in this description and you can use Markdown and
descriptions of you wanted bulleted list a little more formatting you can do that as well and there's not a
complete thought for the place in the topic in the tag that way you can select the correct spelling of a country for example and were used tagset Avery implemented entered there's also a more
recent addition of as services would enable the marking things 7 years but open this up to a wider audience and that we will port have history versioning so you can see immediate it's whose marking things of his like the 1st is the word for animal stuff whether it might be and so just quick demo that
um original with the all
this is what's going on on around
no is divergent as and was not looking at I so I just say I want a new thing
here and I could do it that way and war if I have a new the western data
anybody I you and each if we look at the and so acephate the 1st yesterday was that I was just pretend this is the website of the universe the of the testing was
just pretend is the website is the right sorry about another great example here I will have to do is click on the and the dual bookmark
and something happening that's the 1st them
I we had something here was just take it for granted that it works hi I'm having some sort of weird issue here on consumers loading
of the in the the the the I was going to do it my
local computer in and so is a great
site and I want to look like that so I go to the bookmarklet on Mac that fills in the title URL with the description but they're whatever 1 on you know in the bag you this is that you might on the 1st pass I just bookmark that you don't have time to describe it on ideas that we can review these and come back later to add more details on but in this case the this was Romania and this the places Romania and so I can just like that maybe the topic was in focusing on wasn't that was abandoned finally do that I'm going to add adding notes to say that when you double check the site of something that's what they say that it's now on in there it searchable and
i have to because I just covered there but was just another day so you can edit that
now all the beta in here to open data and in the sense that it focuses on Open
Data sources so I'm not looking to catalog things that you have to buy a subscription to have membership or anything like that there might be some sites that have a combination of open data and both data and but if they do have Open Data I'm interested in in getting even here in it's also open data in the
sense that everything it's in the catalog you can just download that in batch there's an API reading query obviously anything that you type into the search box at whenever you end up with a list of results and you can but on the JASigning get adjacent feed of that simple
schema this is a quick demo that so here I've done a search for Africa and how these results I can look that Jason format and this is
really straightforward simple so if you want to come up with a map interface something that useful data directly from here run queries bring that in because going boxes for countries or whatever you like to do right
so I'm back to geologic to clarify a couple things I it's refining geospatial
data websites we as a whole so 1 website site has a record it's not individual data layers there's lots of other projects that are working on and deciding and how to describe data layers in great detail and provide that information to harvesters and CSW W and all that sort of thing this is something completely different networking at a different scale it's lower resolution data you will and and as a set of
moving from a soul solo effort to a collaborative effort and and I'm going to do this so
I'm 20 all this out so I'm interested in finding collaborators and you get feedback and greatly interested in that and so 1
question I have for you is if you like to be an editor in if you I think you'll be fine to add more resources to this order of really be built out the catalog of let me know
and and there's a Twitter account Gilo they can just we do that if you're not on twitter what can also e-mail me at this address all had this at the end as well I so the
right and on if you just are adjacent suggesting website you know be of the official letter you know any kind of commitment you logging use when say look here's a site it's not new thing much of this but there and so then you just wait
load and all the young and monitoring that and as new things come in all or make sure they get added and we could you know directly questions I've only got 15
minutes let me ask the 1st question if I may
and then recover of but the 1st version of course is what's next and words is going and 1st all more documentation and just this morning I actually officially put the site not and a preview directory and and actually that old me that she is a who who what is the site is behind decided to set a little text there and sort Like an unmarked car I'm ' Morning News like it was there was generated more like an ice cream truck no unmarked scheme truck going around your neighborhood giving out free samples of the data set on obviously I'm 1
account more set websites and there's but just under 700 websites in there currently but I figure there must be at least 15 hundred to thousand websites it should be in here so 1 track those down and get things in
their online out a bit US-centric and because I'm from York state so there's a lot of and maybe a lot of New York State related data the US obviously some international data lot of it's just happens to be the things I've searched for in the past for students who are looking for data and so it's a somewhat arbitrary on so they get a little more international scope for this on 1 idea is to
also harvest sources from a sprawling lists of links and you've seen this before but there's a really great that set
of links and the University of organ library website but here's a page of the
data and it just goes on and on every every state there's now a handful of resources so basically gravel these you else add those in as well and would be a quick way to get a lot of things in that also reviewing in
annotating the data that's currently in there and some of the universe is pulled from a list of links like that allocation those links are and date and the book site maybe God might move so cracking those were 2 errors also adding orientations provide more detail about what and types of data are there and began not going into too much detail and you know this those isotopic Segrate on the tags are things like if you for snow data the isotopic might be climate but to for snow on that would be a useful text of training and and information that will make it easier for people to find that the if the searching that site 1 evening checking is
another thing that should be done and because of the sadness sometimes things go offline so as it temporarily go offline the donor just completely deleted from the catalog but set some sort of system in place that to monitor that and if you have something gone we can assume it's gone forever also
refining the topics and tag that been using the ISO topics which from my so can comprise on the exact number the standard and was that 1 9 1 1 5 but there was given mixed up thank you so so I said topics are about what I'm actually using or sort of more a name so it's not like In July cover business with long From this I have simplified at make move more human readable and there might be some weird 1 off tags that when you get cleaned up so can refining all that in right now the
places of In this ratio by locational bias of being in upstate New York and so I might have you know Tompkins County which is in New York which is in the United States but there's by other Tompkins County is elsewhere but I think that that been adding things in as a place name is not also New York I don't think I've been doing United States of to have a more international scope out it might be worthwhile exploring our data that that makes these connections between the place name so that we do a search for New York least if you don't include all results for United States as well at least you have it clear to the user might want certain is higher due that level and without it becoming too complicated as to what the minimum so I have loaded the project
and no think I might help is website rankings of some of these sources are pretty obscure and for very specialized needs others like on standard you know elevation data for the world others couple sources that are just like places you go straight to study to rank those higher sible short of 1st in those lists might be useful thing how that actually might happen is a good question and you know could be from neutrino much traffic this gets you could you look a lot of what people football and and try to bring things that way 1 or 2 seemed like how many different sprawling lists of links on the web is this web site included on it might be a good way of possible options as as animals a find some
volunteer co-editors and so if
you are interested in helping with this but please feel free to get in touch with me but you
load and the G 2 at Cornell that know and at this point I'll take your questions the Fed but as you go to the editing process to built and to handle duplication of right now this is a really quick check to see if anything at that domain name exists on because 1 thing you run into is so for example the university organ website about unless you know it's the same domain but then they have a page of International Data page of state data on and sometimes you might not so much point to the top level a website but point to the page it actually has a data saying that make it easier in the long run around and some off to link that it's the top level of the site but then they have to figure out where is the hidden I just wanna do inexact matching but that that could be made more robust certainly well Harry defining geo data we talking about stupid GIS ready like it can just automatically go a mapping application be redder PDF maps yeah sheets like Mr. yellow as you get to spreadsheets and as work it's little quite obvious landing like a shapefile intuitive anything like as clearly geospatial data on but attribute data and badly data is all the question on I've typically in not included those but a lot of data is almost ready all it has to do is be joined with the spatial boundaries of 4 to be especially useful and to this point had not included as I think if they were included these will have another on facet that would indicate is it's like pure spatial data always a tabular data like a lot of of websites it so if a state this regional data like it's most all countries willful places out how would you have attacked that way but we use world or what
yeah so I've tried it simple of example there's a set of data that covers some of mainly eastern maybe Central Africa magical at Africa civil rather than tagging with every single 1 of a dozen different
countries and and that's another thing that you
need to find some balance of cataloguers in libraries and are known for attention to detail and he really overboard have fewer and start going down that Devil's on China always in my mind think this is keep it simple it because in the end I and if you do a search for I did have added draw them may results for all of Africa on and there's new for individual countries there might be more websites but the idea that Don you should build an acid Michael not to pinpoint the specific days that you 1 my goal is to give you up a handful that you can then explore and so I think absolute precision is just going to create a level of complexity that that the slow things down I did not any kind of like subscription services are assessed in to the g of a circuit like subscribe to a topic for a tagger location and get updates on on the understanding currently but it seems like that should be pretty easy you on because it does require that the time that the modified and they added on so if your new things and be fairly simple thing to set up an RSS feed for specific query the
the somehow how are you addressing
sites that are aggregators in and of themselves for for example what it environmental mapping I do I get greedy data from databases which is uploaded by researchers who haven't necessarily expose that data anywhere else within database and you can find data for literally the entire world so absolutely every tag would be clickable almost feel that you could set up a separate category for that hour how you dress that yet that's ever thought about there are couple entries in here where you started listing all the topics that
apply it's almost all of them so that point I think would make sense to have a sort of kitchen sink category another sector about something that this is is this is a huge variety of of data and because I think it is kind ridiculous you of the 19 isotopic to try to pick out of the 17 that a fly on the minute you really have to scour the site and check everything we should not be time-consuming process but I think it all in 1 category would possibly make sense it can also be addressed at the user side and now every user may not know intuitively thing about this way but if you don't limit to a topic you can be finding anything whether as a topic or not or what the topic is that involves the user education and Brenda you give them guidance on how to use this to find things as well so you can alive couple options but how do you handle like cities opener URL just different governmental organizations Open Data portals that require of organs like civic absolutely and that's you know kind of another barrier to actually accessing the data seduce indexes and say 0 you're on your own namical organ or you have any other way of handling that anything that sites that open data we still does have to register yeah Becca yeah I think I would evidently include those on how old the individual site or organize themselves well what you have to do their like even like some of the the imagery sites sound when you download you have to have an account you actually download your card of evidence and you get e-mails saying that the thing from the US ready for you and so I'm not really worried about those concerns and in dual low because just the track that with the change of policy you don't have to try to keep up with all that so here's the site go lot go find the and and OR about this this was a big deal and I wonder whether you have come here due look to see can the product the comes from the Open Knowledge Foundation in the UK I had not about juggling compared I but I have thought about you harvesting individual links from those some of the sites I would say that the reason the reason I ask is that it seems to me it so becoming a very popular platform it has a lot of the similarity to June load and I guess from my perspective this is how I know where you decide whether the direction you wanted you loading this perhaps quite parallel to what she can is doing and then maybe focus more attention on the curation of the content which are the metadata records rather than on the tool because certainly a lot of the lot of the things that I'm hearing the suggestions to geodynamo I know are already a part of uh c can be getting most of the Sikh instances that i've aware of it have have looked at that the focus on that data layer level but our where you where you suggesting that users he can infrastructure for maintaining this so as to exactly that there are some people who that using it as the metadata system and some people are in the actual data with that but it it can be used in either way so it is 1 thing it would certainly be a up to looking at that 1 question I would have is how easy is it to add things to that if you have a group of yeah loosely a group of people and that that the equation I would ask but I don't to it is not as it is it is possible to use a hierarchical organization of allowing people to use it as per the US government's implementation so you can you can do this kind of moderation thing with the with having people control their each area of work of capacity so objective yeah any other questions at people when your lunch and what you did in the line of let's look at something it's been to thank you

Abstract You can't make a map without data. A wealth of free and publicly-accessible geospatial data exists on thousands of websites scattered around the world, just waiting to be found and used. But finding the right data for a specific map or analysis requires the knowledge of what geodata websites are out there, and what types of data they each contain. Searching the web can turn up webpages that contain sprawling lists of geodata websites, but such lists are not easily browseable, and are often out of date.Geolode.org is a newly-launched lightweight catalog of geodata websites around the world, searchable and browseable by location, topic, and other tags, so that searchers can quickly focus on the most relevant websites for their geodata needs. An API also provides open access to the catalog's records in JSON format.Geolode's inventory is the collaborative product of a group of librarians and other researchers with many years of experience searching for a wide range of data. We'll talk about how Geolode works, as well as strategies for keeping Geolode up to date, such as harvesting links from all those sprawling lists, and monitoring Twitter for reports of new geodata resources.
