validar-geolocalizacao-poi

You can validate GPS coordinates by running a Python script that uses geopandas and shapely to check points against a Portugal boundary GeoJSON. This ensures coordinates fall within Continental Portugal, the Azores, and Madeira.

Normalizing decimal formatting and fixing swapped latitude/longitude values is achieved by processing geospatial data through a dedicated validation script. It automatically corrects decimal points, resolves inverted coordinates, and removes invalid entries like (0,0).

Yes, geopandas supports boundary checks for the Azores and Madeira when paired with a comprehensive GeoJSON file containing the geographical limits of Portugal. The script performs spatial joins to verify if coordinates reside within these specific regional polygons.

To clean POI data and remove invalid coordinates like (0,0), you process the dataset through a geospatial validation script. This script filters out null or zero-valued points and flags entries that fail geographical boundary validation.

Yes, you can perform reverse geocoding locally to confirm the concelho or distrito of a POI. The validation process includes an option to cross-reference normalized coordinates against local boundary data, verifying the administrative region without external APIs.
