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
