Thematic Mapping

Catchment 3 now supports thematic mapping for the subcatchments layer. This allows visualisation of any subcatchment attribute using a colour gradient.


To access, simply double click on the layer, select the Thematic Mapping tab There are a number of options available for configuration of the thematic mapping. Firstly, select the attribute you wish to map (these are based on the columns configured for display in the Subcatchment Manager). Next, select if you want all unique values assigned a colour, or a certain number of equal ranges, or a certain number of unequal ranges (designed to have a similar number of subcatchments in each colour range). Then click the Add button.
