Note distance is also measured within interiors of polygons. Pixels that are not within 'searchRadius' meters of a geometry will be masked out.
Distances are computed on a sphere, so there is a small error proportional to the latitude difference between each pixel and the nearest geometry.

this:
features
|
FeatureCollection | Feature collection from which to get features used to compute pixel distances. |
searchRadius
|
Float, default: 100000 | Maximum distance in meters from each pixel to look for edges. Pixels will be masked unless there are edges within this distance. |
maxError
|
Float, default: 100 | Maximum reprojection error in meters, only used if the input polylines require reprojection. If '0' is provided, then this operation will fail if projection is required. |
