Title: Module 4 – Mapping Density and Finding What’s Inside
Course: MASTER-GIST-1120-Patton

Density factors in the impact area along with the values associated with an area; making comparisons across features more precise. Students will view how density displays data differently from straight counts or totals; do comparisons between dissimilar areas by showing the data as a concentration; and determine which fields are not suitable for mapping density, summarizing counts or totals.

Students will also study the basic concept of data overlays. Since GIS data deals with relationships among datasets; many analysis can be done using these relationships such as selecting features and creating summations and comparisons with the attribute information.
