An ArcGIS analyst is working with a mosaic dataset created from Landsat imagery. The images are displayed in the mosaic dataset using a 7,4,3 band combination (Short-wave Infrared 2, Red, Green). The analyst needs to use the mosaic dataset to determine relative biomass in the area of interest.

Which raster function should be used?

  1. NDVI
  2. Identify
  3. Spectral Conversion
  4. Zonal Remap

Answer(s): A

A GIS administrator wants to share map documents with other staff who have access to the administrator's drive. The administrator does NOT want staff to have to copy the data to their local drives to open the map documents. The administrator must change the local system paths to UNIC paths in all map documents.

How should the GIS administrator accomplish the task?

  1. Use a Python script to find and replace workspace paths.
  2. In ArcCatalog, rename the databases and data folders.
  3. In ArcMap, Save A Copy to a new location.
  4. From the Contents pane, click the red exclamation points to fix the data sources.

Answer(s): C



A GIS analyst using ArcGIS Pro needs to georeference several non-georeferenced aerial photos. All aerial photos have a similar spectral signature, the same geographic location, time and season, image orientation, image scale, and band combination. The analyst has a single georeferenced raster in a known coordinate system for the same location, which has the same image properties. The analyst adds the single georeferenced raster to a new map with an imagery basemap layer and then applies the following workflow:

Imagery tab > Georeference > Prepare group > Fit To Display > Adjustment group

Which next step allows the analyst to georeference the remaining non-georeferenced aerial photos?

  1. Auto Georeference
  2. Add Control Points
  3. Import Control Points
  4. Transform

Answer(s): A

An ArcGIS user needs to update a coastline feature class after a recent weather event. The user receives aerial imagery taken 1 week after the event. All features will NOT need to be updated, but some areas have experienced soil loss due to erosion. Rather than redigitizing the entire coastline, the user wants to update the existing coastline feature class based on the new aerial imagery.

Which edit tool is recommended to update this feature class?

  1. Copy Parallel
  2. Trace Feature
  3. Reshape Feature
  4. Trim Line

Answer(s): B
