If
xis a collection of spatial feature, it would be handy to have SDA_spatialQuery(..., what = 'mukey') return adata.frameorlistfor each feature. This would support "I want those map unit keys that intersect / overlap with the following features, in row-order please" style questions, without a secondary spatial overlay of the polygons.This would come at a cost:
byFeatureiteration would be a little slower due to the extra overhead.The text was updated successfully, but these errors were encountered:
