I'm looking for a package to develop a simple offline GIS desktop application that works on a tablet/laptop for using it on the terrain (namely for annotating existing maps).
The program has following requirements:
- Able to show/load vector and image data offline (formats doesn't matter much)
- Able to edit basic data. So able to save vector data.
- Desktop or Android
- We want to create our own routines for editing the data.
I have looked a bit to ArcGIS SDKs, but offline is in beta there so I was wondering if there are other (maybe open source) toolkits that some of you have experience with.
I'm not interested in things like buffering, geoprocessing,... We want to be able to show vector and image data and provide our interface on top of that.
