“As we treat map layers as numbers using Map Algebra, the sequence of operations of Layer1 + Layer2 * Layer3 should be executed according to the algebraic rules in the sequence of Layer2 * Layer3 + Layer1. “

“Defining a watershed involves six major steeps, and some of them are included here. Arrange them in the best sequential order of a, b, and c, ignoring the missing step(s). “

“During a neighborhood operation, all moving windows have the same dimension and the same set of weights within the study area”

“Viewshed can be computed for a view point location, a line or an area. “

There are two general types of buffer in respect to direction. What are they? Explain their differences.

MA: When vector overlay operation of intersect is applied, what is/are the possible feature type(s) of the outputs conceptually, given the following input feature types? Overlaying line features with polygon features.

“In formulating a cartographic model, say to conduct a suitability analysis, different criteria are given different weights, while options within a criterion should be ranked. “

“In hydrologic analysis, although flow direction is affected by many factors, aspect is the most important determinant.”

“In network analysis, the best route is the least cost route.”
