An ArcGIS user has a soils polygon shapefile
Which conversion is necessary in order to ensure that the soil polygons do NOT overlap or have gaps?

• A.converting the shapefile to a polygon=feature class within a geodatabase feature dataset
• B.converting the shapefile to a raster dataset within the geodatabase
• C.converting the shapefile to a stand-alone polygon feature class within a geodatabase
• D.converting the shapefile to a terrain dataset with the geodatabase

An ArcGIS user runs the Central Feature geoprocessing tool on a polygon feature class. The output feature is far north of the center of the feature class Why Is the output feature off center of the feature class?

• A.There are more polygons In the northern part of the feature class
• B.The polygons in the northern part of the feature class are larger
• C.A weight field is not specified
• D.The feature class is not in the same promotion as the data frame

An ArcGlS user maintains a street signpost database with measure in terms of two route feature classes:
distance from the nearest school and distance along the street.
If the two feature classes are created from the same source line feature class, which geoprocessing tool will support calculating one event from the other?

• A.Transform Route Events tool
• B.Locate Feature along Routes tool
• C.Overlay Route Events Tool
• D.Near tool

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 visually inspect the image to make sure there are no obvious errors that would compromise the sp accuracy
• C.They should compute an RMSE and compare the results to the results of a Landsat image
• D.They should compare the image to surveyed control points of high accuracy and compute an RMSE

An ArcGlS user receives two shapefiles that are defined with the same projection and represent features in the same study area. When they are displayed together in ArcMap. the difference of their locations in coordinate space is so large that they are barely visible when viewed at their full extent.
How can the user determine whether the projections of the shapefiles are correctly defined?

• A.by comparing the shapefiles to a correctly projected dataset that has a large enough extent to encompass the study area.
• B.by examining the metadata of both shapefiles to determine the projection processes applied to the data1.
• C.by systematically changing the spatial reference of the data frame until the shapefiles correctly align.
• D.by using the Spatial Adjustment toolbar to move the shapefiles to the same part of coordinate space.
