When is it appropriate to manage your raster datasets using a mosaic dataset?
Right 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. Right 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?
Right 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? Right Ans - Mosaic methods
T/F: If you selected the option to build overviews on a mosaic dataset, then
the statistics will also be generated. Right Ans - True
T/F: Any modifications you make in the Image layer will not affect the
properties of the mosaic dataset. Right 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. Right
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? Right 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. Right 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. Right 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? Right 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?
Right Ans - By Attribute
What is required to create a mosaic dataset? Right 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? Right
Ans - Query the mosaic
What is the first step in managing your raster data using a mosaic dataset?
Right 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? Right 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. Right Ans - True
You have obtained three large raster datasets with three different resolutions.
What is the best method to manage these raster datasets? Right 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
Right 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 Right 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 Right Ans - Closest to Viewpoint
Mosaic Method that...
- Used when method needs to be constant across the surface Right Ans -
Closest to Northwest
Mosaic method that...
-Orders based on metadata attribute and difference in base value Right 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 Right 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 Right Ans - Overviews
Workflow for creating and adding rasters to a mosaic dataset Right Ans - 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?
Right Ans - -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? Right Ans - Overviews are generated and
stored, by default, in a folder next to where the mosaic dataset resides.
Why are overviews not automatically built? Right Ans - 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? Right Ans - By
selecting a feature in the Contents pane
What is the window called for working with maps, scenes, tables, layouts,
charts, and reports? Right Ans - A view
In which type of dockable window do the Symbology and Geoprocessing
functionalities occur? Right Ans - A pane
Pro Project Structure Right Ans - -a main project file with an APRX file
name extension
-a toolbox
-a file geodatabase
-folders for working in the project
