geopop
Python library for getting populations size given a place name
>> gp = GeoPop()
>> gp.population("Moscow", 30)
>> 14029857
>> gp = GeoPop(data_dir="/Users/nyddle/geopop/data")
>> gp.population("Moscow", 60)
>> 16115484This library works in a bold way: on initialization it loads into memory all data that resides in the data directory specified by the user or data included by default in the "data" directory. When a 'population' method is called it simply scans through all the data points and sums the population for those that appear to be in the specified radius.
One can easily extend the library geo coverage by putting more {country_code}.txt files into the data folder.
Performance improvements:
- search only in the country-specific subset of data
- sort datapoints by lat/lon for faster search
- use rtree/sqlite to index the data
