I have a map with a shp file containing information on land use. The attribute table has over 10,000 rows.
I need to classify this information into 6 groups to represent 6 colors on my map. I know you can re classify by adding on a new column on the attribute table and put each row into the 6 groups, however this would take years to do 10,00 rows.
Is there a quicker way to do this?
Many thanks all
