Question No : 1
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?

• A.Copy Parallel
• B.Trace Feature
• C.Reshape Feature
• D.Trim Line

Question No : 2
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?

• A.Auto Georeference
• B.Add Control Points
• C.Import Control Points
• D.Transform
