We're one of four partners to make the list in the Fall 2019 issue of ArcNews' Esri Partner Solution Stories. These stories illustrate our capabilities as Esri Partners in helping users get the most out of their data. To optimize efforts and resources, the City of San Diego and the County of San Diego in California share a GIS land base and data warehouse managed and maintained by the San Diego Geographic Information Source (SanGIS). This arrangement, called a Joint Powers Authority (JPA), allows the two separate government organizations to combine resources to meet common objectives—in this case, sharing data and providing up-to-date information to the public.
SanGIS 's mission is to maintain and promote GIS data for land base maintenance, data warehouse management, and public access to GIS data. SanGIS partnered with Quartic Solutions to implement the Esri Geospatial Cloud by setting up ArcGIS Enterprise on Amazon Web Services (AWS) to achieve those goals.
SanGIS also uses the Esri Geospatial Cloud to create and maintain San Diego County Assessor map books. Previously, two organizations did data entry: the County of San Diego Assessor’s Office first entered parcel data in CAD. SanGIS reentered that data into its GIS and added lot data. This resulted in data duplicates. However, with ArcGIS Enterprise on AWS, each organization now enters its data directly into the GIS, eliminating duplicate entries and publishing the data much faster than in the past. The operating costs of creating and maintaining the map books have also been reduced.
Centralizing these workflows required moving the maintenance of several mapping activities from CAD to ArcGIS. Quartic Solutions created custom GIS edit, report, and publication tools to mimic the CAD system’s functionality and product outputs. Now, the City of San Diego and the County of San Diego can reliably send data back and forth, saving time. The county assessor plans to expand this system to include other updates for the landbase. This versatility has allowed SanGIS to use a single solution to meet two goals: data sharing and collaborative database maintenance.
