Since the data collection was done indoors, we were not able to use GPS to determine panel locations. Instead, they were measured from known indoor physical structures using measuring tapes and laser range finders then cross-referenced with highly accurate as-built CAD drawings of the buildings. We used mobile tablets and a customized data collection application to enable our geospatial analysts, subcontracted electricians, and Tobyhanna engineers to collect and update the data and photographs for the electrical panels and seamlessly incorporate the data into an ArcGIS v.10 geodatabase.
