ACTUAL 2025/2026 QUESTIONS AND
100% CORRECT ANSWERS
When is it appropriate to manage your raster datasets using a mosaic dataset? -
(ANSWER)You want to use small to large collections of your raster data for
managing, visualizing, performing many geoprocessing analyses, and querying.
List the advantages of organizing raster data in a mosaic dataset. - (ANSWER)-
Store, manage, view, query, and share small to vast collections of lidar data
-Perform raster-level operations on lidar data
-Complete on-the-fly processing
-Display data faster at any scale
When you add a mosaic dataset to ArcGIS Pro, it is added as a mosaic layer that
appears in the Contents pane as a special group layer with a minimum of three
layers. What are these layers called and what does each display? -
(ANSWER)Boundary, Footprint, and Image.
-The Boundary layer displays the boundary of the mosaic dataset
-The Footprint layer displays the footprints for each raster within the mosaic
dataset
-The Image layer controls the rendering of the mosaicked image.
What are rules for ordering overlapping rasters when viewing the mosaicked
image called? - (ANSWER)Mosaic methods
,2
T/F: If you selected the option to build overviews on a mosaic dataset, then the
statistics will also be generated. - (ANSWER)True
T/F: Any modifications you make in the Image layer will not affect the properties
of the mosaic dataset. - (ANSWER)True
T/F: You have gathered 59 county-level, 1-meter IKONOS images. You would like
to create a mosaic dataset using these images. However, you want to exclude
areas of cloud cover. It is appropriate to generate overviews in this scenario
during the process of adding rasters to the mosaic dataset. - (ANSWER)False
You have built a mosaic dataset using a set of raster data. You want to select
specific tiles within the mosaic dataset and download them to your local
computer. How can you accomplish this task? - (ANSWER)Add the mosaic dataset
to ArcGIS Pro, select the specific tiles, lock to selected rasters, and download the
selected rasters.
You modify the extent of the footprint of a mosaic dataset. Which of the following
statements is true?
Pixels are modified.
There is no loss of image data.
You cannot crop the polygons.
You are editing the source raster dataset. - (ANSWER)There is no loss of image
data.
,3
T/F: You have created a mosaic dataset using a set of LAS files, and you modify
the Image layer in ArcGIS Pro to better visualize the mosaicked image. By doing
so, you are changing the source data. - (ANSWER)False
You have received a mosaic dataset with several layers. How do you display a
specific layer of interest and extract information about the layer? -
(ANSWER)Query the layer.
You have acquired GeoEye-1 imagery with and without cloud cover. You want to
view it with no cloud cover at the top. Which mosaic method will you use? -
(ANSWER)By Attribute
What is required to create a mosaic dataset? - (ANSWER)You should have write
access to the geodatabase and an ArcGIS Desktop Standard and ArcGIS Desktop
Advanced license.
You receive a mosaic dataset with several layers. How do you display a specific
layer of interest and extract information about that layer? - (ANSWER)Query the
mosaic
What is the first step in managing your raster data using a mosaic dataset? -
(ANSWER)Create a geodatabase if you do not have one.
Which mosaic method do you use to order rasters based on a user-defined
location and nadir location? - (ANSWER)Closest to Viewpoint
, 4
T/F When you add raster data to a mosaic dataset, the raster data is not stored
within the mosaic dataset. - (ANSWER)True
You have obtained three large raster datasets with three different resolutions.
What is the best method to manage these raster datasets? - (ANSWER)Create a
single mosaic dataset and add the three raster datasets to the mosaic dataset.
Mosaic method that...
-Sorts rasters with their center closest to the view center placed on top
-Sees little distortion in the images, you want to view the centers of the images -
(ANSWER)Closest the Center
Mosaic method that...
-Uses the point on the earths surface directly below the satellite on top
- Shows buildings that appear to stand straight - (ANSWER)Closest to Nadir
Mosaic method that...
-Used when viewer needs to see all sides of a building around an object
-Shows the sides of buildings so that you can identify features such as entrances
and windows - (ANSWER)Closest to Viewpoint
Mosaic Method that...
