GIS Final based on Final Exam Review
Questions and Answers 100% Solved
Overlay analysis Correct Answ_two or more input layers are processed to create an output
map algebra/raster calculator Correct Answ_rasters with the same extent and resolution can
be analyze through multiplying, adding, or subtracting
Boolean raster Correct Answ_a raster with cells that contain a 1 to indicate true or 0 to
indicate false regarding a specified condition
Boolean overlay Correct Answ_evaluating rasters with Boolean operators to evaluate areas
where combinations of specific conditions exist
weighted overlay Correct Answ_Overlays several rasters using a common measurement
scale and weights each according to its importance.
distance function: euclidean distance Correct Answ_used to calculate distances from a set of
vector features
, least cost path Correct Answ_A path between source and destination that has the least cost
density functions-simple density v.s kernal density Correct Answ_simple density function
assumes that the weight value occurs exactly at the feature location while kernal spreads the
value over an area with max at the middle and decreasing around it
Interpolation Correct Answ_estimates values in between point measurements
Tobler's Law Correct Answ_all places are interrelated, but closer places are more related than
farther ones
surface analysis-slope Correct Answ_calculates the steepness of a surface such as a DEM
with output in degrees or percent
surface analysis-aspect Correct Answ_direction of steepest slope, expressed in degrees from
0-360
