Esri: Distance Analysis Using ArcGIS
UPDATED ACTUAL Exam Questions and
CORRECT Answers
The backlink raster is a cost direction surface created when you run the Cost Path tool. -
CORRECT ANSWER - False
What are the units of measure for cell values in a Euclidean (straight-line) distance surface? -
CORRECT ANSWER - X The units you specify
If you want the software to reclassify your raster values into new values based on a standard
classification method, which of the following options would you use? - CORRECT
ANSWER - X Reclassify based on a table
If you were trying to allocate cells in a raster to a source and determine distance and direction
from each cell to the closest source, which single tool would you run to give you all these
surfaces? - CORRECT ANSWER - Euclidean Allocation
Which tool allows you to write Python expressions to evaluate rasters or surface data? -
CORRECT ANSWER - Raster Calculator
Euclidean distance tools can be used to determine horizontal distances between locations but
cannot be used to determine vertical distances. - CORRECT ANSWER - False
When creating any Euclidean surface, you have to determine the output cell size. What is a best
practice when choosing an output cell size? - CORRECT ANSWER - Choose a cell size
that matches the data you already have so you do not imply more resolution than there really is.
If you were performing a least-cost path analysis for building a new road through an established
