  1. My proposal for a possible hackathon topic: Concept/prototype for a mobile (planetary) OGC/WMS client app

  2. cool hackthon for mobile, wish I could be there. Based on Chiara's prototype perhaps using Cesium: https://cesium.com/blog/2016/05/18/an-introduction-to-cesium-android-apps-with-cordova/  Also the treks seem to work fairly well on a phone (also Cesium, panning is a little wonky).

    openlayers and leaflet seem to have good mobile support. 

    Tony Anecito has a few planetary globe apps using our WMS layers (Google Store) and PSK available: https://apk-dl.com/mars-xplorer/com.myuniportal.android.apps.marsxplorer  I think he uses WorldWind JS.

    I still need to test the 1TB CTX and 19TB HiRISE tiled WMSs in various places like leaflet and openlayers. (works in Arcmap, QGIS, MarsTrek). It would be an interesting test to try to use these services directly in Aladin (or understand how it might be configured to work - via a proxy server. We are thinking about using Lunaserv perhaps in front for JMars...) https://bit.ly/HiRISE_mosaic or blog post: https://www.esri.com/arcgis-blog/products/arcgis-online/imagery/observing-the-red-planet/

    While this set of Tiled WMSs (above) have 16bit topography (HRSC/MOLA and HiRISE DEMs) available, I think WorldWind and maybe Cesium uses a weird raw 16-bit server back-end to support 3D elevation (Chiara knows more),

      BTW, Trent Hare is the19 TB hirise in web mercator? it did work OK (as per twitter..) but then I realised we might have mixed eqc with wemberc? ;-/ (wink) ? either way, it was usable and worked (one would just need ot use the same crs if not already

      1. No just in degrees. I tend to only support map services in degrees and polar only. I am fairly adverse to Web Mercator. Hopefully that trend will die as Google moves to a globe viewer. I always understood Web Mercator was originally used such that directions were more "cardinal" (north is up, east to the right) for driving applications. 

        By using degrees, we can cheat and allow applications which don't understand planets to at least draw the layers. That doesn't mean it is good and there is always the potential for measures to be reported incorrectly. But it seems more thick clients (QGIS, ArcMap, etc.) will do the right thing and project correctly from degrees to a (i.e.) a Mars defined map projection within the application. For the Esri served layers (1TB CTX, 19TB Hirise, etc.), they are tagged as on Mars, but they use Esri codes. These Esri codes are in GDAL (including most planets), but that doesn't mean all viewers are going to use them. Thus for web clients, we have needed to modify the code in specific places (like the measure tool) to understand the body we are currently one (e.g. open layers, leaflet).


        The latest on IAU projection codes is that they will be finally available in the Proj (v6) library within a few months (I hope). That won't solve a ton of issues but it should allow for programs which use GDAL to more easily use them, then we can work on the web clients...

  3. The syn/post-workshop iteration (both for attendants and eventual remote participants) is going to be on:

  4. Trent, you want to download the app from the hackathon in this repository and see your layers on your phone running as a leaflet/cordova app...
