Before we can transform data (geometry, imagery) from one coordinate system to another we need to create projection files.  In this example, we create projection files that represent geographic coordinates (latitude, longitude) and UTM zone 19S (WGS 84).

The EPSG code for latitude/longitude is 4326.  In versions of Muk3D from v2018 onwards a projection file for geographic coordinates is automatically created when starting a new project and stored in the <project>/projections directory.
