MANAGING RASTER DATA USING
ArcGIS BY ESRI EXAM
What is required to create a mosaic dataset?
You should have write access to the geodatabase and an ArcGIS for
Desktop Standard and ArcGIS for Desktop Advanced license. -
ANSWER
Which statement about mosaic dataset overviews is true?
Overviews are low-resolution images. - ANSWER
Which of the following options improves the display (both appearance
and performance) of your mosaic dataset?
Building overviews - ANSWER
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 ArcMap, select the specific tiles, lock to
selected rasters, and download the selected rasters. - ANSWER
You have created a mosaic dataset using a set of LAS files, and you
modify the Image layer in ArcMap to better visualize the mosaicked
image. By doing so, you are changing the source data.
False - ANSWER
You have a mosaic dataset from your client. You want to use the mosaic
dataset with other spatial data on the web. When you import the data
, into ArcMap, you realize that the mosaic dataset is in NAD 1983 HARN
UTM Zone 5N. What would you do if you wanted to change the
projection to WGS 1984 Web Mercator Auxiliary?
After a mosaic dataset is created, you cannot change its projection.
Go to the mosaic dataset properties and edit the Spatial Reference
section. - ANSWER
When you add raster data to a mosaic dataset, the raster data is not
stored within the mosaic dataset.
True - ANSWER
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. - ANSWER
You have a mosaic dataset from your client that looks like the graphic on
the left. When you copy this mosaic dataset to your file geodatabase, the
mosaic dataset looks like the graphic on the right. What may have gone
wrong in this situation?
The overviews were not copied with the mosaic dataset. - ANSWER
You receive a mosaic dataset with several layers. How do you display a
specific layer of interest and extract information about that layer?
Change the mosaic method to By Attribute.
Query the mosaic. - ANSWER
