Introduction
Have you ever wanted to load elevation data from online, reproject this to an appropriate model coordinate system, maybe use some GRASS GIS tools, and then use this data as the basis of your Landlab model grid? Then look no further!
This notebook:
Imports SRTM elevation data into a GRASS project using bmi_topography.
Offers opportunities for advanced GRASS calculations using imported elevation data.
Loads a GRASS layer (the STRM elevation data imported earlier) as a Landlab RasterModelGrid for future modeling endeavors.
Exports elevation data from GRASS GIS as a .tif file
Classroom organization TBD

Lab notes This lab can be run on the lab (for educators) and jupyter (for general use) instances of the OpenEarthscape JupyterHub: just click one of the links under the Run online using heading at the top of this page, then run the notebook in the "CSDMS" kernel.
