GIS / Mapping Open Source SW Dev

I am getting an abandoned open source mapping suite updated and optimized for drone imagery. Some initial work has been done and I have a few more tasks that need completing. [login to view URL] SW consists of mainly: Java JavaScript Python CSS HTML (android app) 1st task will be sorting out two bugs that were introduced with previous commits. A: A function in the android app that was working prior to the issue commit has stopped working and prevents the android app from connecting to the server (geoserver). It has been verified the issue is server side and not in the app. B: A preview window in the web client (geonode) that was previously working disappeared with the last commit. We will need to bring this preview window back. 2nd task is to fix a rendering issue with the web inteface that is part of this suite of sw. It is based on openlayers and there is something preventing maploom form rendering the mapping data correctly. Its been verified that the issue is with maploom because the server hsoting the data has a "vanilla" openlayers interface that you can demo data with and in this interface the mapping data renders fine. 3rd task is adding additional map tiles to the server (geoserver). A previous developer added additional levels of "zoom" to the maploom and android interfaces to allow for the viewing of very detailed tiff based maps. Geoserver only has vector tiles for the levels previously available. Now that more levels of zoom are present additional map tiles (vector tiles) need to be added. If these three tasks are completed there might be additional tasks we can discuss for this project.
