Lab #9a: Introduction to Spatial Analysis
1. What is spatial scope and what are the three types? Spatial scope is the extent or area of the input data
that are used in determining the values at output locations.
Examples:
a. Local Operation: It uses the data at one input location to determine the value at a corresponding output
location.
b. Neighborhood: Uses data from both an input location plus nearby locations to determine the output value.
c. Global Operation: uses data balues from the entire input layer to determine each output value.
2. What are the different types of spatial selection operations? adjancency and containment
3. What are the two types of Algebra used in queries? boolean and set algebra.
4. Is there a feature dataset in the geodatabase? Yes, 'LosAngeles.'
5. What features classes are present? Lines.
6. How many features (records) exist in the Vegetation feature class in the Lab9aData.mdb geodatabase? 10896.
7. How many features (records) exist in the new VegCov feature class after running the dissolve operation? 9
8. How many wetland features (records) were selected? 404.
9. How many features (records) exist in the new "VegCov_Clip" feature class? 1450.
10. How many features (records) were selected? 355.
