Question 1

Describe two applications of spatial analysis using GIS (to solve real-world problems or concerns).

Answer 1

There are many different answers to this question,which would involve examining how two different layers of data relate to one another spatially,or how items relate to one another over some sort of distance or within a buffer.To use two examples from the text; 1)using spatial analysis to see how many registered sex offenders reside within a certain distance of a school (by creating a buffer around the schools and seeing how many plotted address points are within the buffer); or 2)which parcels of land are on the floodplain (by taking the parcel layer and overlaying it onto another layer representing the flood plain).

Question 2

An area of spatial proximity around a point refers to which GIS operation?

A)Spatial join
B)Buffer
C)Closed circle
D)Union

Answer 2

B

Question 3

Site suitability analysis is used to

A)select which objects fall within a buffer zone around a point.
B)determine which areas are "useful" or "not useful" in spatial analysis.
C)merge all polygons with a value of "1" together,as well as all polygons with a value of "0" together.
D)forecast land use changes into the future.

Answer 3

B
