1 Embedding Digital Images in a File Geodatabase Cynthia Wanschura GIS Technician Elena Robisch GIS Program Manager Zion National Park, Utah A Case Study from Cedar Breaks National Monument, Utah

2 Cedar Breaks National Monument, Utah The highest point = 10,662 feet Giant amphitheater, spans some three miles and is more than 2,000 feet deep Due to heavy snowfall the boundary fence is removed each winter Photo from Photo by Lee Rademaker

3 The Project Peg Simons, Volunteer In Park: –GPSed the fence line –GPSed & photo-documented potential problem areas Integration of digital photos with GPS points

4 Link Photos with Table Records

5 Why did we choose the method of embedding photos in a geodatabase? No addition software or extensions required, easy sharing Provided with data, we were not part of the field process One Image per Point Option of managing by the geodatabase Photo by Paula Hamilton

6 Creating the Raster Field Left-click

7 Creating the Raster Field

8 Decision Time… Managed vs. Not Managed

9 Managed by the Geodatabase: Sounds Good, Right? Benefits: –No further need for image management –Automatically moves photos with spatial data Downsides: –Unstable –Large file size –Always providing photos with the spatial data Recommendation: Do not have the geodatabase manage the photos.
