“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.”

Across the entire U.S., geocoding through address matching using 2010 or earlier TIGER street database was highly accurate because the street database had the coordinate of every house.

Assuming that you are given the following datasets: flood zone map of the U.S. with polygons delineating areas (in polygons) prone to flooding; a map showing all properties in polygons that had filed a flood insurance claim in the past five years. It is believed that the flood zone map needs to be updated. Describe clearly and precisely the data/variables, process, specific functions-operations and parameter values that are required to complete the following task: identify the areas in the flood zone map that need to be updated and the types of update. If you need to make any assumptions, explicitly state these assumptions.

  Given the above three raster layers and using map algebra concepts and functions, what should be the output layers (OutLayer) of the following operations? Provide your answers by cells from left to right, and then top to bottom. OutLayer = Overlay (LayerA + LayerB). Ignore Layer C in this question.

“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. “
