Topographic Map
Story Maps
ArcGIS Online
Google Maps
2
Tier 4 of the Geospatial Tech Competency Model are foundational “soft-skills”
False
True
3
How does a 3D model differ from a 2.5D model?
2.5D models only use 1 z-value and 3D models use multiple z-values
2.5D are rendered as contour lines and 3D have crossing contours
3D models only use x and y coordinates
There is no difference
