2. Calculating the area of overlap between two polygon data layers
3. Determining the area within a set distance from a point, line or area feature
4. Calculating the number of observations within a set distance of a point, line or area feature
Ans: 3,4
5. What is reclassification?
1. The process of combining one or more data ranges into a new data range to create a new data layer.
2. The process of combing two or more data layers
3. The process of simplifying data in a data layer
4. An analytical technique based on point data.
Ans: 1
6. What is Manhattan distance?
1. The distance between two points in a raster data layer calculated as the number of cells crossed by a straight line between them.
2. The distance between two points in a vector data layer calculated as the length of the line between them.
3. The distance between two points in a raster data layer calculated as the sum of the cell sides intersected by a straight line between them.
Ans: 3
7. Which of the following spatial interpolation techniques is an example of a local, exact, abrupt, and deterministic interpolator?
1. Thiessen polygons
2. TIN
3. Spatial moving average
Ans: 1
8. What is the difference between slope and aspect?
1. Slope is the gradient directly down the fall line, while aspect is the direction of the fall line relative to north.
2. Slope is the direction of the fall line, while aspect is the gradient of the fall line.
3. Slope is the distance down the fall line from the top of the slope to its bottom, while aspect is the percentage gradient of this line averaged over its full distance.
4. Slope is the gradient of the fall line relative to vertical, while aspect is the direction of the fall line relative to the line of greatest slope.
Ans: 1
9. What is location-allocation modelling?
1. A method of site location based on overlaying multiple siting criteria maps.
2. A method of allocating resources within an area of interest using buffer analyses
3. A method of matching supply with demand across a network by locating a limited set of resources using network analysis
4. A method within network analysis used to determine delivery routes
Ans:3

1. 25
2. 120
3. 10
4. 3125
Ans:2
