zip file that will be used during this tutorial, which contains both the centreline_UTM17N.shp data file (showing city streets) as well as the V2-1910-172.tif image file (a scanned map of the block). In this example, we will match intersections represented on the scanned map with a shapefile of city streets. Georeferencing requires a spatially referenced dataset that will be used to provide locations on the scanned map with their associated coordinates.
