Why Your Area Calculation Is Wrong in GeoPandas (And How to Fix It)

📰 Medium · Data Science

Learn why GeoPandas area calculations may be incorrect and how to fix them for accurate GIS analysis

intermediate Published 5 May 2026
Action Steps
  1. Check the CRS of your GeoDataFrame using the `crs` attribute
  2. Verify that the geometry is in a projected CRS
  3. Use the `to_crs` method to transform the geometry to a suitable projected CRS if necessary
  4. Calculate the area using the `area` attribute of the GeoDataFrame
  5. Compare the results with other area calculation methods to validate the accuracy
