Questions With 100% Correct Answers
When is it appropriate to manage your raster datasets using a mosaic dataset?
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.
-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?
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?
Mosaic methods
T/F: If you selected the option to build overviews on a mosaic dataset, then the statistics will also be
generated.
True
T/F: Any modifications you make in the Image layer will not affect the properties of the mosaic
dataset.
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.
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?
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.
There is no loss of image data.
,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.
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?
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?
By Attribute
What is required to create a mosaic dataset?
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?
Query the mosaic
What is the first step in managing your raster data using a mosaic dataset?
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?
Closest to Viewpoint
T/F When you add raster data to a mosaic dataset, the raster data is not stored within the mosaic
dataset.
True
You have obtained three large raster datasets with three different resolutions. What is the best
method to manage these raster datasets?
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
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
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
Closest to Viewpoint
Mosaic Method that...
- Used when method needs to be constant across the surface
Closest to Northwest
Mosaic method that...
-Orders based on metadata attribute and difference in base value
By Attribute
-Reduced resolution layer that enhances performance by making copies of the original data at a
decreasing resolution
-Written as .ovr files and stored in a single file next to the source raster files
-Speed up the display of raster data by retrieving only the data at a specified resolution that is
required for the display
Pyramids
-Reduced resolution raster dataset created to increase display speed and reduce usage
-Lower-resolution copy of the data appears quickly while viewing entire mosaic datasets
-Typically begin where Pyramids stop
Overviews
Workflow for creating and adding rasters to a mosaic dataset
1. Create a geodatabase
2. In geodatabase, create empty mosaic dataset and its schema
3. Add raster datasets to the mosaic dataset
4. Modify the mosaic dataset (make updates to the boundary and footprints, add more raster data,
and so on)
5. Define and build overviews for the mosaic dataset
What does Calculating Statistics do when working with raster datasets?
-Help to enhance the rendering of your raster data
-Increase a map's drawing performance for your raster data source
-Perform certain other tasks, such as applying a contrast stretch or image classification.
Where are overviews stored?
Overviews are generated and stored, by default, in a folder next to where the mosaic dataset resides.
Why are overviews not automatically built?
They take additional space and time, and you may want to build them at your convenience.
How would you get contextual tabs to display on the ribbon?
By selecting a feature in the Contents pane
, What is the window called for working with maps, scenes, tables, layouts, charts, and reports?
A view
In which type of dockable window do the Symbology and Geoprocessing functionalities occur?
A pane
Pro Project Structure
-a main project file with an APRX file name extension
-a toolbox
-a file geodatabase
-folders for working in the project
Shows the various parts of the project that have been created for you, including connections to
default toolboxes, databases, styles, folders, and locators
Project Tab in Catalog Pane
On the Insert tab, where would you find Import Map, add a database connection, and add a folder
connection?
In the Project group
Contextual tabs for vector feature classes
-Feature Layer
-Labeling
-Data
Which ArcGIS Pro component contains licensing information, the ArcGIS Pro version, and
management options for portal connections?
The settings page
A GIS analyst has created an ArcGIS Pro project to analyze data. When the analyst opens the blank

-You can view the data in both a 2D map or a 3D scene in the same project.
-You can view the data in a 2D map and a 3D scene and link the views to one another.
