LabDescription

Have you ever wanted to load elevation data from an online data source, reproject the data into an appropriate model coordinate system, maybe use some GRASS GIS tools, and then use this data as the basis of a Landlab model grid? Then look no further! +

LabDescriptionShort

A demonstration of fetching elevation data with the Topography data component, reprojecting and tuning it with GRASS GIS, then loading it into a Landlab RasterModelGrid. +
