Introduction to Geographic Information Systems 9th Edition By Chang – Test Bank
Chapter 11 Vector Data Analysis
1) List three variations in buffering.
2) Provide an application example in which a buffer zone is used as an inclusion zone.
3) Provide an application example in which a buffer zone is used as an exclusion zone.
4) The concept behind buffering is similar to proximity in spatial data query. Provide an example in which you must use buffering instead of spatial data query.
5) Explain the point-in-polygon operation.
6) A line-in-polygon operation produces a line layer, which typically has more records (features) than the input line layer. Why?
7) Explain the polygon-on-polygon operation.
8) Define “slivers” from an overlay operation.
9) Describe an example in which areal interpolation can be used as a problem-solving tool.
10) Describe a scenario, in which Intersect is preferred over Union for an overlay operation.
11) Intersect is an overlay method as well as a spatial join option. Will you get the same result from both operations?
12) What is the minimum mapping unit?
13) How does Ripley’s K-Function differ from nearest neighbor analysis?
14) Define “spatial autocorrelation.”
15) Both Moran’I and the G-statistic have the global (general) and local versions. How do these two versions differ in terms of pattern analysis?
16) Both Erase and Eliminate can remove map features from a layer. Explain how the two commands differ in usage.
