Creating digital data sets
Tools to enter spatial data include:
- Digitisers. A
map is placed on a digitising table and a puck
or cursor is used to trace map features. The cross hairs of the puck
are placed over points lines and polygons so that they record coordinate
information for the map objects.
- Scanners create
a raster digital image of a map
- Key board. Someone
can type in the necessary data
