Get terrain elevation for a given polygon
pointDTM_get(polygon, distance = 1, print_iter = TRUE)
polygon
: the polygon layer with only one object (its area is limited to the 20 ha * distance parameter), the input coordinate system must be EPSG:2180distance
: distance between points in meters (must be integer and greater than 1)print_iter
: print the current iteration of all (logical, TRUE default)a data frame with vector points and terrain elevation (EPSG:2180, Vertical Reference System:PL-KRON86-NH)
