Overlay Mapping

What is Overlay Mapping ?
A common problem with any map, whether stored in printed form or on computer, is that there is either too little or too much information displayed. The mapmaker chooses what to put on the map. The client often wants different information. Overlay Mapping keeps everyone happy, by providing flexibility in the way a map is displayed, whilst displaying every item of data to its best advantage.

Overlay Mapping Advantages
Overlay Map has a number of layers or overlays that can be turned on and off as required. Not only can you choose how much information you want on the screen at any one time, you can also choose which order the layers are displayed in. Overlay Mapping thus gives you exciting new possibilities never available in a fixed or printed map. By comparing information on different layers, you can make new discoveries and find data inter-relationships only possible before with expensive GIS packages.
