The 30 Arc-Second Elevation Model GTOPO30

The Global 30 Arc-Second Elevation Data (GTOPO30) is a 30 arc second (approximately 1 km) global digital elevation data set that contains only elevation data and no bathymetry. MathWorks announced that the gtopo30 function to read the data would be discontinued and that one should use the readgeoraster function instead. Here’s the updated recipe from Chapter 7 of the MRES book (Trauth, 2021). Continue reading “The 30 Arc-Second Elevation Model GTOPO30”
