pyproj is a Python interface to the PROJ library for cartographic projections and coordinate transformations. It lets Python applications convert coordinates between coordinate reference systems and perform geodesic calculations.
Use cases
- convert lat/lon coordinates to utm in python
- transform coordinates between coordinate reference systems
- reproject shapefile or raster coordinates
- python bindings for proj library
- calculate geodesic distances between points
- look up CRS definitions by EPSG code
When to choose
- you need accurate coordinate transformations in Python
- you work with GIS data and need CRS handling
- you want a maintained wrapper around the industry-standard PROJ library
When to avoid
- you need a full GIS toolkit with geometry operations - use geopandas or shapely alongside it
- you are not working with geospatial coordinates
