Surface Menu

The plan menu controls all options for plan drawing windows.


Draw: With this command you select a data set to be drawn. You may draw as many windows as you like as long the maximum number of windows supported by VIEWER is not exceeded (in V1.0 it is 10 but this may be different in later versions). You may draw data in order you like. Most importantly you may draw the same data set as many times as you like. This latter option is useful if you want to look at the same data set in a number of different ways (ie. different colours, etc). The drawing window will always be drawn the same size initially but you may modify its size at any time.

 

Overlay: This option overlays on the data a number of different, and additional pieces of data. When the overlay options is chosen all plan windows will have this data overlayed on it. The data may be overlayed are (1) the grid points of the calculation (2) the actual grid used (3) the drainage network of the study area.
