Surface

!DANGER!

slope(), aspect(), curvature(), and hillshade() with method='geodesic' assume the WGS84 ellipsoid and require coordinates in degrees (geographic CRS). Passing projected coordinates (metres) to the geodesic method produces wrong results. Use method='planar' (the default) for projected data.

Note

All surface functions output float32 regardless of input dtype. Edge cells within the 3x3 kernel radius are NaN by default (boundary='nan').
