Esri ArcGIS Distance Analysis EXAM-Questions with Correct
Answers/ Verified/ Latest 2024/2025
The backlink raster is a cost direction surface created when you run the Cost Path tool. -
✔✔False
What are the units of measure for cell values in a Euclidean (straight-line) distance surface?
- ✔✔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? - ✔✔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? - ✔✔Euclidean Allocation
Which tool allows you to write Python expressions to evaluate rasters or surface data? -
✔✔Raster Calculator
Euclidean distance tools can be used to determine horizontal distances between locations
but cannot be used to determine vertical distances. - ✔✔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? - ✔✔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 residential area, which of the following factors would be the most important in
the analysis? - ✔✔Property value
Suppose that you used the Euclidean (straight-line) Distance tool and created a direction
surface based on the location of regional airports. Each cell value in the direction surface
indicates the direction to the nearest regional airport. Which cell value will correspond to
the airport location? - ✔✔0
