Read Global Multi-resolution Terrain Elevation Data (GMTED2010)

Source: R/data_ruggedterrain.R
read_ruggedterrain.Rd

Reads the GMTED2010 spatial metadata for terrain elevation as an sf object. This metadata includes polygon geometries for GMTED2010 tiles and summary elevation statistics such as minimum, maximum, and mean elevation values.

Usage

read_ruggedterrain()

Value

An sf object

Details

The function performs the following steps:

  1. Locates the local GMTED2010 dataset file using get_pgfile

  2. Unzips the file to a local directory

  3. Reads the spatial metadata shapefile from the extracted data
