Read Global Multi-resolution Terrain Elevation Data (GMTED2010)

Source: R/data_ruggedterrain.R
read_ruggedterrain.Rd

Unzips and reads the GMTED2010 spatial metadata as an sf object. This function locates the local GMTED2010 dataset file, extracts it, and reads the spatial metadata shapefile for use in elevation calculations.

Usage

read_ruggedterrain()

Value

An sf object containing the GMTED2010 spatial metadata with elevation information including minimum, maximum, and mean elevation values

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
