Lab 5: Thematic Maps & workspaces
You have a parcel file that contains a field containing property values.
How do you see the property value patterns throughout your
project study area using MapInfo?
In this lesson, you will learn how to create various types of thematic
maps such as Ranged, Dot Density, Graduated, Pie, Individual, and
Grid.
Within the ranged thematic map, you will learn the different
classifications that determine range values: natural break, standard
deviation, equal count, and equal range.
