1.   Aerial photos can also be employed to produce a map of known features within a region.

2.   They used the data to produce a map showing the location of older and weaker rock zones.

3.   If such maps are produced by hand or drawn by a pen plotter, the increasing magnitude of the variable is shown by increasing density of line-shading.

4.   Coloured maps can be produced on a dot-matrix printer by using a printer ribbon that is divided into three parts horizontally along the length of the ribbon.

5.   Useful maps can be produced using standard printer technology.

6.   High-quality pen-and-ink maps are produced on a graphplotter.

7.   One point that must be borne in mind is that such maps cannot be produced using Landsat MSS or TM data alone.
