Hello everyone, my name is Milvry and I work at Quantour as a JS specialist. I'm so excited to be a part of community because you know it's my very first time at OSCoG, so I'm happy to be here. And today I want to talk to you about the state of open area map and how it links with disaster response.
00:24
So, let's start. It's not a secret that the imagery is vital during critical moments like disasters. Imagery from satellites, from UAVs or other aircrafts is becoming increasingly available after a disaster.
00:49
And it's difficult to define, to recognize what is available and is accessed. So, to solve this problem, open area map was invested.
01:03
And what is open area map is it's a simple open host to provide access to imagery for humanitarian response and disaster preparedness. So, but first I want to introduce you to an organization called Hometarian Open Strip Map Team.
01:23
So, it's an NGO, also it's a global community of people who can make some efforts to fulfill the map and contribute. I mean map, I mean open strip map, of course, to support humanitarian aid and disaster preparedness.
01:41
Their work is very crucial for creating maps of regions where other data might be unavailable or outdated, supporting efforts in disaster relief. So, Hotossum collaborates with various organizations, including NGOs, governments, companies,
02:03
local communities to improve mapping data and enhance their humanitarian aid. Including the company I work for, Quantor, is a global company, is a geospatial data and real-time risk manager provider for many organizations.
02:21
Mainly we work into the disaster management. So, for Hot, we developed such type of applications like Disaster Ninja. It's an open source platform, I would say, that provides you with some metrics of the quality of the map.
02:46
And with another bunch of features like disasters, like quantum population, and you can also select your area of interest and get some analytics here.
03:01
So, but now we are talking about the Open Aerial Map and it's project that was founded in 2007. To be honest, in general, the disaster management is the most applied thing that could be invented with the development of this project.
03:25
That's why in 2015, the project came under the umbrella of Hot. And Hot relaunched the platform in 2015, and then since 2022, Quantor joined the effort.
03:46
Initially, we conducted some redesign research of the platform, improved user experience, and then we worked on creating a global mosaic layer for the project, for the platform.
04:03
Our effective collaboration with Hot laid the foundation for establishing a random of understanding between us, which was established to help each other on developing tools to enable the usage of open map imagery and data to improve livelihoods and support disaster recovery.
04:28
Yeah, that's why I'm here. And you can easily start just openmap.openarealmap.org on your browser, and then you can reach the platform.
04:45
What we can see here, it's a platform that provide you some information about what Open Aerial Map is on the left side. And also you can see some last update, uploads here, but most of the platform is placed by a map, clustered map with a number of uploads here.
05:08
And if just you scroll down, the map can be complemented by imagery. Of course, you can use navigation or just search panel to search some area of
05:29
interest, for example, your homeland, and check if there are any available open imagery available here. So, yeah, and that's why I can, I should mention Maxar because they
05:49
have an open data program and makes its imagery available during critical moments. It's very useful because it significantly aids in humanitarian response during the critical events like disasters, of course.
06:07
It was also noting that Maxar provides both prayer and post-event data, which is crucial for assessing losses. And despite some difficulties in uploading imagery automatically on the Open Rail Map, because platform now
06:29
does not support the stack catalog, thanks to the many volunteers from HOD and people like Batu. Thank you, Batu. Imageries can be found on the platform.
06:43
For example, Batu wrote a code for automatically uploading all the imagery from the Maxar hosts and then assembling them into one single image or mosaic to upload much faster on the platform. So, and the great news here is that you can also make your contribution to the platform just uploading any image here.
07:09
So, the platform is a way for users to contribute to OMImager database, and here you can put some metadata. For example, title, platform, sensor, date start, date end, location of the imagery from local file, from the link, from any cloud.
07:32
And also some another specific metadata is available here, and also it's very cool as it's a platform by
07:49
uploading your imagery here, you clearly state the license of the imagery to use it or to share it.
08:01
And now the three subtypes of CC by email licenses is available here. Available here is CC by, CC by share alike, and CC by non-commercial. So, from the technical standpoint, I would say that the magic that happens under the table.
08:30
A raw image just uploaded to a cloud server where there lies under the compression and then transformed to the COGS.
08:43
And they can remain in this format on the cloud. They can simultaneously be accessed as TMS, as a layer on the OM platform, and also as part of global mosaic map.
09:03
So, the project itself fits with workflow, emergency mapping workflow of HOD, called Tasking Manager, and you can find some advice imagery that can be used on the project on Tasking Manager here.
09:25
Another achievement that was made by Kontur is editing the edition of the mosaic into the OSM Editor layer index.
09:41
Its index is a list of open layers that can be used in any OSM editors, like ID or JOSM. So, you can find the open area map here as well. And another use case of imagery usage is you can use any image in your own analysis.
10:06
You can just copy the link of TMS and easily edit it into your project in QGIS and conduct some kind of analysis like functional zoning of your hometown or another kind of analysis.
10:29
It's very useful because imagery is under the very clear license. Together with HOD, besides uploading, you can use the browser for the filtering of the imagery.
10:47
Together with HOD, we established the regular meetings around the open area map. So, we are starting to raise the community around the project.
11:01
We are people who like to do imagery and help into disaster response as well. So, if you want, I can easily add you on the call.
11:22
Just feel free to reach out to me and it's available. Also, on the bottom of the slide, I took your codes to community chats on Telegram. And the other one leads to the Slack channel on the HOD awesome Slack space.
11:48
So, of course, around the project, we have some future plans. And we have some pain points around, for example, automatically uploading.
12:04
Project does not support stack for now. And, yeah, also we want to enhance image search and enhance UX. And redevelop the technical stack and bring it to a new level.
12:26
Also, we have some plans to develop open area map version 3 that supports even the 3D models and point clouds based model. But to be honest, development requires funding.
12:44
And currently, you can support the project financially by donation, by the time of donation to HOD. But please leave your comment in the comment field here, like I did. I want to contribute to the open area map.
13:02
So, also as another way how you can help us, if you find any interesting tender or grant or wealthy man, you can contact us and just take it from there.
13:21
So, I think that's it. And, yeah, bonus slide, it's a layer. This layer, it's a map made by using our new application called Atlas.
13:41
And it represents your count of imageries of OAM per hexagon here. Yeah, it's very cool if you can recognize your homeland country here. For example, you can see that around Japan we have a lot of hexagons covered by imagery, but it's satellite imagery, of course.
14:05
And, yeah, also we made another layer with a number of pixels per hexagon, but it's not available now to edit on the slides. But the way we have such kind of beautiful visualizations.
14:25
Yeah, and that's all from my side. If you have any questions, you can ask me. And I also leave there some links and contacts for the project. Thank you.
14:44
Thank you, Milvary. So, anybody has any questions? I will start then. I have one serious and one not question. Which one do you want first? Let's start from serious. Okay, so there's a selector for imagery license.
15:10
That's CC BY, CC BY-NC and CC BY-SA. And it's known that non-commercial licenses are very vague. So what if I use this imagery to map something and then an agency will sell the data that I map?
15:27
I know this might be not your part, but what is maybe the reason for including that? Can we use the imagery? Thank you, it's a great question. I guess if you use any image, you should put the source and just
15:48
recognize that it's not available to purchase some information mapped thanks to this image. So maybe you should use another source?
16:04
It's OpenStreetMap. You can't choose which data to use and which not from OpenStreetMap. The typical use cases of usage of OpenIRL map is mapping on OSM mainly.
16:25
The range of use cases is not very big. You can use image for your research using QGIS. Also, when we participated in the redesign project for the OpenIRL map, we defined three user persona for this project.
16:50
There is no person who want to sell any data because usually the project is aimed to be like a right hand, right arm for the OSM.
17:21
It's a tricky question because there is not enough clarification. If you made some information based on the imagery, it already can be counted like transformation of the initial information or not.
17:54
It's a very complex question. I think CC-BY-NC is not classified as an open license.
18:02
So maybe you might want to highlight those imagery just in case. It's a good note, yeah. Any other questions? So just I don't hug the channel. Non-serious question. Can you share any weird things that have been uploaded to OpenIRL map?
18:28
It's a good question. If your word sync has a projection, it's not necessary to upload any imagery in optical channels.
18:46
It's not to be an RGB. It can be also some NDVI layers, et cetera. No cases of vandalism was reported on the project.
19:06
I would say that now you can try, but we have some. The HOD is monitoring for the project and can notify you if you made something wrong or not very useful.
19:33
I would say so. Thank you. I was just thinking maybe I could upload a picture of my cat to OpenIRL map or something.
19:43
If your cat has a projection, please. This will be very funny. Yes, it does. It's phosphagic. Any other? It's a similar question actually.
20:00
There are some procedures to validate the imagery that can break some security. For example, if someone uploads the imagery of critical infrastructure or some military equipment, is someone looking out at this point?
20:21
Anybody can upload whatever they want. Many years ago I was living in Belarus. In Belarus you have restrictions of using any aircraft in some military areas or everywhere.
20:44
Now it's forbidden everywhere. Usually it's regulated by state.
21:01
The project is aimed to be accessible by aircraft lovers, people who like to do something around them.
21:23
It depends. If the state requires, have a free requirement to use it, it's okay.
21:41
I don't know. I would say also that there was not any evidences about this kind of scenarios.
22:03
Just to add a comment, also to question the OpenSTMAPP community about the license. When I check OpenSTMAPP guidelines, it is actually they don't want to have any data non-commercially. Because you cannot track and they can promise about it.
22:23
But at the same time there is no clear explanation about you can't use CCNC image. It is also now very clear whether we can use this or not to edit OpenSTMAPP. At the same time it is being used. Maxar always releases data with CCNC and it is being used for a while.
22:47
So it is a big use. It would be nice to clarify this issue. For other security-related things, I'm also not an expert, but in OpenSTMAPP right now you need to sign in with Google.
23:01
If Google can promise that you are not a dangerous person, the OpenSTMAPP also can promise that. So you have more, how do you say, that kind of check whether it can be violated or not. So it is not really less secure than any other platform in my opinion.
23:25
Thanks for this comment.
