I am creating maps for surveyors showing different sections of roads. The start and end points need to be clearly visible so I am using a Region IndValue thematic map.
However, sometimes when an area has a very large number of segments the odds are that the large number of colours displayed mean some sections are similar to the colour of the backdrop mapping.
I have remedied this slightly by removing these colours from the default template.
But I was wondering if there was a way to have smaller range of colours as the only thing I need to ensure is that lines that are touching each other do not have the same colour? Is there a way to do this?
