■ Locate specific coordinate points and measure the geodetic distance
between points.
■ Visually communicate relative values and scale with themed displays.
■ Create contour maps to help you analyze 3D terrain.
■ Use raster-based theming to analyze elevation, slope, and aspect, drape
map data over surfaces and view the data in 3D, and more.
■ Create buffer zones based on feature properties and select objects based
on their proximity to a buffer. Save the buffer as its own feature class, for
future reuse.
■ Overlay two geospatial layers to compare their data. Save the resulting data
as a separate layer, which you can join to attribute data or theme.
