9. Digitizing Vector Layers from a Georeferenced Backdrop
Our georeferenced scanned map can now be used as a backdrop to digitize vector layers. Vectors can be points, (poly)lines or polygons. In this exercise we are going to digitize:
- Mountain tops as points
- Rivers as polylines
- Lakes as polygons
We will create these vector layers in a GeoPackage spatial database. In that way we have all layers together in one file, instead of using separate shapefiles.
