Read and merge DEM tiles from IGN DBALTI or RGEALTI as a function of WGS84 coordinates

Description

Read and merge DEM tiles from IGN DBALTI or RGEALTI as a function of WGS84 coordinates

Usage

read_dem(coord, buffer = 1000, dep, source = "db_alti")

Arguments

coord	latitude and longitude of centroid (named numeric vector, decimal degrees).
buffer	circular buffer around the centroid (numeric, m).
dep	departement code number used to index DEM data (numeric).
source	DEM database to be used (character). "db_alti" is a national database at 25x25m resolution. "rge_alti" is a departement-level database at 5x5m resolution, with 1 - 20m source data.

Value

a digital elevation model as a spatial data object (stars)
