K-means clustering of the DEMIX data set

The DEMIX database (Guth, 2023) contains statistics from 6 test 1 arc second DEMs (ALOS, ASTER, CopDEM, FABDEM, NASADEM, and SRTM) compared to high resolution reference DEMs. The database contains 236 DEMIX tiles (Guth and others, 2023) and has 7 tile characteristics for each tile.

A K-means clustering of the database, and an additional set of 4 land cover and landform classifications for the 236 DEMIX tiles produced variable numbers of clusters.

This data set includes five databases including the clustering results, a figure showing the scatterplots showing the relations among the tile characteristics in the database, and map showing the location of the clusters.
