DatabaseSchema  
One-About the SQLite database schema
Updated May 4, 2011 by conor.br...@gmail.com

SQLite Database Schema

id: A basic identifier, must be a unique integer

name: The name of the map

ekey: Encryption key, can be any random string of characters and numbers

fname: The filename of the map JPEG. This must match the end of the URL

url: The full URL to the location of the image

The next 4 columns come from the world file, in order

min_longitude

max_latitude

lat_per_pixel

lon_per_pixel

And then the last two columns...

polygon_points: These are the points, in pixels of the polygon of the map. On the final georeferenced image, there are areas that are not covered by the map. We want to make sure we are within the map polygon so we must get the points from that.
