AT 319 Week 7 - Buffering and Overlay

This weeks lab covered the concepts of buffering and overlay, two common

cartographic operations. A buffer zone is an area that is within a given distance from a map feature. When you buffer on a set of features, the output is a set of polygons. Overlay is a join operation that is commonly used. The deliverables for this week are as follows:

• Hugo, MN Lake and Road Buffers (Figure 1)

• Hugo, MN Areas suitable for campgrounds (Figure 2)

• Hugo, MN Areas suitable for Campgrounds only on PRIVATE LAND (Figure 3)
