Capital allocation refers to:

Cartographic modeling is broader than map algebra because it employes map algebra functions and other spatial analysis functions to perform the analysis.

“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. “

  Given the above three raster layers, 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. Layer C is not used in this question. OutLayer = ZonalAverage(LayerA, (Is.LayerB>=50)) where LayerA is the input layer, and the second parameter of the zonal function defines the zones (or the zone layer).

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

“Spatial analysis functions or operations may be categorized according to their spatial scope (i.e., the spatial extent of input area that is used to determine the values in the output locations). What are the three spatial scopes? , , “

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 polygons features with polygon features. 

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

“If DEM data are highly accurate in reflecting elevation on the ground surface, viewshed analysis should be 100% certain in determining the intervisibility between any two locations on the ground.”

Which traffic management system initiative assigns flight arrival times to regulate arrival at the impacted airport?
