FindNearestRiverSegment: Find nearest river segment
In ECCC-MSC/Basin-Delineation: Finds upstream area and upstream stations
Description
Usage
Arguments
Value
Description
Find the nearest line segment (river) to a point (station).
Spatial objects should be in an appropriate coordinate system (i.e. not
lat-long) otherwise they will be projected and this adds to processing time.
If CRS does not match between the stations and the rivers they will both be
projected into Canada Albers Equal Area conic.
Usage
1
FindNearestRiverSegment(spatialPoint, riverLines, HYBAS)
Arguments
spatialPoint
A SpatialPointsDataFrame of the desired station
riverLines
A SpatialLinesDataFrame of the HydroSHEDS river network
Value
dataframe of nearest lines (attribute table of matches)
