Hello Ahasan and Russel,

Both of you recommended that I speak with the folks at OpenMapKit and it
just happens that Nicholas was the very first person to reply :) We are
going to have a short chat and hopefully there are ways that we can
collaborate together (I can think of quite a few!).

Since I've had a few similar questions off list, let me answer them here in
one thread:

In looking through the Android app, I am seeing a map with an interesting
> spherical projection with a PNG base map.

The raster based tiles are rendered using Mapserver out of OSM data in
4326. Here is some code that shows the raster image data of those tiles:
http://plnkr.co/edit/xwE2DbsdRPx48Y3QK4Bw?p=preview I styled them myself
based on some mapserver samples :)

What map rendering library are you using? I haven’t seen this before.

That is the AmigoCloud renderer. It does vectors and rasters and is fully
GPU accelerated OpenGL

Are these all features you included in your mail support offline ?

Yes, all these features are supported while offline.

Have you tested this app for doing any mapping ?

Yes! We have State Agencies, private environmental consulting firms and
transportation authorities using this every day.

Thank you all and I hope some of this work will help HOT in the near future.
