The Project Peg Simons, Volunteer In Park:– GPS’ed the fence line

– GPS’ed & photo-documented potential problem areas

Integration of digital photos with GPS points

Link Photos with Table Records

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 bythe geodatabase

Decision Time…Managed vs. Not Managed

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.
