Description Usage Arguments Details Examples
Like gBoundingPoints
but only returns the indices of points contained within a bounding box
1 | gWhichPoints(allpoints, b_box)
|
allpoints |
A |
b_box |
A set of bounding coordinates in matrix form like those returned from |
Rather than returning the spatial object, this give the indices of points within a bounding box. It's more useful for re-merging attributes (Since gBoundingPoints strips a SpatialPointsDataFrame to a SpatialPoints object). Or, better still, subsetting.
Note: all inputs should be of class sp::SpatialPolygons|Points
1 2 | gWhichPoints(points.spdf, bbox(container_polygon))
all_the_points_spdf[gWhichPoints(all_the_points.spdf, bbox(container_polygon)), ]
