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
Action Steps
- Check the CRS of your GeoDataFrame using the `crs` attribute
- Verify that the geometry is in a projected CRS
- Use the `to_crs` method to transform the geometry to a suitable projected CRS if necessary
- Calculate the area using the `area` attribute of the GeoDataFrame
- Compare the results with other area calculation methods to validate the accuracy
