The use of interpolation and extrapolation are both
excellent methods that are used in GIS to extend our
knowledge beyond sampled areas?
False
Core area mapping is used to take a series of point samples
in GIS and create a polygon?
True
The diagram below shows an example of fixed radius
interpolation. What is the value at the unknown place

5
In order to conduct a viewshed analysis in GIS you must
have at least 3 GIS layers which are:
Elevation, surface feature locations, and sample viewpoints
, After recoding the diagram below, you should do a dissolve.
