I'm currently writing a geographical web application. Obviously it needs access to some geographical data, like terrain elevation and the location of roads. The twist is that the application must be able to work disconnected from the internet - i.e. getting its GIS data from a server on the local network. I'm assuming that I can't use t...

Hi, I'm currently developping an application to manage my pictures on an Android phone. I developped an algorithm to classify the pictures based on the geographical coordinates (latitude, longitude) of each photo. To test my application on the android emulator in Eclipse, I manually imported a bunch of photos from my computer to the SD...
I've got a table that I'd like to present. However, a lot the information in it is only useful in aggregated or visual form. For example, the country column it itself is boring, but a aggregating all the entries of a country would be really useful. Coordinates are in there as well, so any solution should be able to present stuff on a map...
I'm building a website in Django, and I want one of my datatypes to be a geographical polygon. I want to mark points on a map (say, in Google Maps) and then store the resulting polygon in the database. Is there any way to do it that will save me the work of typing all the longitudes and latitudes manually? I guess I'm looking both for...

Hi all, I'm looking for good GIS solutions that work on a relatively smaller, detailed scale. Specifically, I was wondering what APIs or toolkits are available for mapping out spaces in a building (like rooms, hallways, shelves). This need not be a 3D solution, like one might envisage for architectural CAD-type drawings. Something relat...
I have a method that that is suppose to calculate the bearing between two geographic coordinates (in 40.7486, -73.9864 example format). I am however, having an issue where the heading that it calculates is different from the heading I calculate using a tried and tested application. For example, the initial bearing between of the follow...
