WebbNot all projections have an EPSG code. The projection in the PROJ.4 string below does not have an EPSG code, for example. We’ll transform all the sfc objects to this projection because it is the one used by the NLCD raster layer we’ll introduce later in this lesson. Webb30 dec. 2024 · The most important part of area computation by geopandas is that you must use the CRS that corresponds to an equal-area projection. In this case, the simple cylindrical equal-area projection (epsg=6933) is good to use. The data files can be obtained from:- data_source. The relevant code should becomes:
