Authors: Lynn Zhang

City of San Jose is migrating muni water data from Intergraph Geomedia to ESRI LGIM to make GIS data easy to share & deploy maps/apps. LGIM scheme is used to design data model. Data comes from 2 sources: GPS data/Geomedia data, which needs to be preprocessed. These data are examined technically, visually, and statically. Bad GPS data are filter out first and request to reGPS; Join IDs were checked for accurate. LGIM is flexible to fit adjusted and enhanced feature classes & domains.
