python Programming Glossary: lon

http://stackoverflow.com/questions/1425149/reverse-geocoding-without-web-access

able to determine the state province to which a latitude longitude pair maps and detect when we have moved from one state.. you would like to be based on the latitude and then the longitude or vice versa . Define polygons for each of the states.. sort of calculation to determine in which polygon a lat lon pair lies. I am not sure exactly how to go about this. HTML..

there. The records in the datastore can match based on longitude latitude radius so for instance an URL like lat 22.45.. latitude radius so for instance an URL like lat 22.45 lon 43.12 r 294200 is a parametrization that matches Rio de Janeiro.. match Rio de Janeiro and not Sao Paulo. Rounding off the longitudes and latitudes to 2 decimals is also decided as good enough..
