Geographic Information System (GIS)
This technology allows users to overlay and analyze multiple layers of geospatial data to reveal patterns and relationships.
What is a key benefit of GIS?
On the blank map provided: draw and label the Equator (0° latitude) and the Prime Meridian (0° longitude), add at least two lines of latitude north or south of the Equator, and add at least two lines of longitude east or west of the Prime Meridian.
Draw and label the Equator, Prime Meridian, and at least two latitude lines and two longitude lines with correct terminology.
