PTMapper has the ability to import data from a number of sources. This means that you can often create a new map using data received from third parties e.g. DXF’s, Shapefiles, scanned maps, etc. To be able to do this you would first need a blank map to import your data.
Even if you plan to import the data onto an existing map, it’s often a good idea to test the data first by importing it into a blank map.
