Using the Spatial Analyst IDW (Inverse Distance Weighted) tool an ArcGlS user interpolates a point feature class to a raster. The user notices that some high point values near the edge of the feature class seem to have a dramatic effect on the output.
This occurs even in areas that are far from the high edge values.
Which two parameters should the user consider changing in the IDW tool? (Choose two)
A. z-value field
B. search radius
C. power
D. output cell size
E. weight
Given an elevation surface, a raster of forest stands, and a point feature class of saw mills, which analysis is used to determine the optimal route from each forest stand to the nearest saw mill?
A. Network
B. Viewing
C. Proximity
D. Distance
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
An ArcGIS has created a definition query on a parcel feature in a personal geodatabase to only show areas classified as residential. The user's company has decided to update all personal geodatabase to file geodatabases.
When the ArcGIS user updates the source data to point to the parcel feature class in the file geodatabase they receive the following error.
"One or more layers failed to draw:
Parcel: An invalid SQL statement was used. [Select Shape FROM Parcel WHERE [Parcel] B residential]
Parcel: An invalid SQL statement was used"
What is the correct SQL statement for the file geodatabase?
A. {Parcel} = residential
B. [Parceii = residential
C. Parcel = residential
D. "Parcel" = residential
An ArcGlS user created a geoprocessing script in which the output layer's symbology property is set to an existing layer file. The user intends to share the tool with another ArcGlS user. How can the user share the script tool while maintaining the symbology in the output layer?
A. Share the script tool while the sumbology layer file embedded in it
B. Publish the script tool as a geoprocessing service to ArcGlS Server
C. Distribute the Toolshare folder containing the script tool and related data
D. Upload the script tool as a model to an FTP site
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
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)
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
An ArcGIS user regularly receives a large volume of data in shaped le coverage, and table formats. The user has a Python script tool for converting the data to a standard feature class format and writing it into a file geodatabase. The user schedules the script to run automatically, based on the update schedule, but the tool is sometimes unable to write to the database.
Why is the tool sometimes unable to write to the database?
A. Another user has a schema lock on the output feature class
B. The scheduled task is unable to access the output feature class
C. The service is published as a map service
D. Another scheduled task is running simultaneously
A representation layer has been defined using the option to save changes to the geometry of the supporting feature. If the geometry of the feature is modified using the tools from the Representation toolbar, what will be modified?
A. the Shape field of the feature
B. the shape In the override field
C. the feature attributes
D. the override attributes
