I have about 20 million sets coordinates from the Philadelphia, PA, USA region. For each set of coordinates I would like the FIPS code of the corresponding census tract.
I looked at this thread: Free api to reverse geocode latitude, longitude to census tract? However, I think any http/API solution would be too slow. Also, I don't think QGIS could handle so many points.
Ideally I'd like to use Python for my solution. Maybe there is a function that can import polygons from a shp file and identify which contains a given latitude/longitude pair?
