# Relative Elevation Model
Tutorial on creating a [relative elevation model](https://ngmdb.usgs.gov/Info/dmt/docs/DMT16_Coe.pdf) in Python using [xarray](https://xarray.pydata.org/) and [datashader](https://datashader.org/).
Based on [*Creating REMs in QGIS with the IDW Method*](https://dancoecarto.com/creating-rems-in-qgis-the-idw-method) by [Dan Coe](https://twitter.com/geo_coe).
