When is it appropriate to manage your raster datasets using a mosaic dataset?
Ans: 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.
Ans: -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?
Ans: 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?
Ans: Mosaic methods
T/F: If you selected the option to build overviews on a mosaic dataset, then the statistics will
also be generated.
, Page |2
Ans: True
T/F: Any modifications you make in the Image layer will not affect the properties of the
mosaic dataset.
Ans: 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.
Ans: 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?
Ans: 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.
Ans: 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.
Ans: 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?
, Page |3
Ans: 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?
Ans: By Attribute
What is required to create a mosaic dataset?
Ans: 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?
Ans: Query the mosaic
What is the first step in managing your raster data using a mosaic dataset?
Ans: 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?
Ans: Closest to Viewpoint
T/F When you add raster data to a mosaic dataset, the raster data is not stored within the
mosaic dataset.
Ans: True
You have obtained three large raster datasets with three different resolutions. What is the
best method to manage these raster datasets?
Ans: 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
, Page |4
Ans: 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
Ans: 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
Ans: Closest to Viewpoint
Mosaic Method that...
- Used when method needs to be constant across the surface
Ans: Closest to Northwest
Mosaic method that...
-Orders based on metadata attribute and difference in base value
Ans: 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
Ans: 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
