13.2.5 Topography Map Color scale description
Previous software versions have always used the same color scale for Topography maps (absolute and
normalized), this is called “Classic” color scale. This software version introduces the possibility to switch the
scale to the ISO
3
and ISO 2005
4
color scale, by going to Measures section of the settings. The color scale
option selected affects any topographic map drawing in the ALADDIN HW3.0 application and in the printed
reports (also the custom ones).
The Classic and ISO absolute color scale are shown in the following figure for the same topography map.
