What is Draping Field Maps with NTF Data about?

This tutorial shows how to georeference a field map slip to overlay it on a digital elevation model (DEM) from Ordnance Survey data. It involves: 1) Scanning the field slip and importing it. 2) Georeferencing the field slip by assigning real-world coordinates to control points. 3) Obtaining a DEM file in NTF format, converting it to ASCII format importable in ERDAS, and georeferencing it. 4) Displaying the georeferenced DEM and field slip together in ERDAS for analysis.
