Mosaicing Rasters

In this lecture, we will look at other types of operations that we can perform on rasters:

  • Mosaicing
  • resampling
  • reprojecting

We will continue to use packages like stars and units

Mosaicing: Elevation

We will demonstrate the use the three tools, by applying them to a Digital Elevation Model (DEM).

This is what we try to achieve:

Downloading DEM data

DEM stands for a digital elevation model

There are many data sources

The most helpful website for downloading DEM is: http://www.webgis.com/terr_world.html
