EADP19-001 ArcGIS Desktop Professional 19-001 Question and Answers

Question # 4

An ArcGlS user adds an ESRl World Imagery service from ArcGlS Online to an empty Arc Map document.

The user then adds a polygon feature class representing national parks to the map.

The spatial reference of the national parks feature class is:

• Datum North American Datum 1927

• Linear units meters

• Protection Albers equal area

The user intends to digitize new national park boundaries using the features in the imagery.

What should the user avoid doing in the edit session?

A.

transforming the coordinate system of the national parks to match the Imagery from the Web service

B.

projecting the coordinate system of the imagery to match the national parks

C.

reprojecting the national park feature class and transforming the coordinate system to match the imagery from the Web service

D.

editing the park boundary laver without changing the original coordinate Systems

Question # 7

A local government geodatabase use case requires that airport noise regulation areas be deleted if a corresponding airport point Is deleted.

Assuming that one airport can contribute to only one noise regulation area, what is the appropriate way to model the requirement of this use case?

A.

a simple relationship class with noise regulation areas as the origin and airports as the destination

B.

a simple relationship class with airports as the origin and noise regulation areas as the destination

C.

a composite relationship class with airports as the origin and noise regulation areas as the destination

D.

a composite relationship class with noise regulation areas as the origin and airports as the destination

Question # 8

AnArcGIS user is tasked with editing a layer containing a large number of features, using another layer thatis in a different coordinate a system as reference. The user adds the layers in ArcMap and starts an editsession. A warning message about editing data in a different coordinate system is displayed.

What is the most efficient way to edit the data to avoid potential distortion in the data?

A.

change the data frame's coordinate system to match the coordinate system of the layer being edited

B.

project the reference layer so the coordinate system matches with the one that needs to be edited

C.

georeference the reference layer and start a new edit session

D.

create a geodatabase topology with the two layers and add a rule so new data always snaps to thereference layer

Question # 9

A raster dataset called rasterl.tif contains many pixels with values of NoData.

Which map algebra expression changes NoData values to 0 (zero) in the output raster dataset while leaving all other pixel values the same?

A.

con(rasten.tif = NoData. 0 raster!, tif)

B.

con(rasten.tif = = NoData, 0, rasterl.tif)

C.

con(isnull(raster1.tif). 0, rasterl.tif)

D.

con(setnull{raster1.tif), 0, rasterl.tif)

Question # 10

When designing a geometric network where should the feature classes be stored?

A.

inside a single feature dataset

B.

outside a feature dataset

C.

inside any feature datasets sharing the same spatial reference

D.

inside a topology

Question # 11

An ArcGIS user has a project that requires using an image with a spatial accuracy of 5 meters Root Mean Square Error (RMSE) or better.

How should users verify the spatial accuracy of the image?

A.

They should verify that the image resolution is less than 5 meters

B.

They should compare the image to surveyed control points of high accuracy and compute an RMSE

C.

They should visually inspect the image to make sure there are no obvious errors that would compromise the sp accuracy

D.

They should compute an RMSE and compare the results to the results of a Landsat image

south

C.

east

D.

west

Question # 13

Which purpose does synchronization serve in a multiuser editing environment?

A.

manages relationship class rules in both parent and child geodatabases

B.

defines a fitter area in which changes are recognized

C.

reconciles and posts changes to a child or parent geodatabase

D.

creates replicas for editing by end users
