The project required Spatial Vision to redevelop an existing tool, re-writing the back-end from custom developed code to instead use DELWP’s enterprise MapShare environment, based on ArcGIS Enterprise and Geocortex essentials.
The first challenge was to develop a data model for the aquifer data which would allow it to be queried very quickly – the source aquifer data comprises many statewide grid datasets. A “publication” spatial data model was designed and a geo-processing task developed to transform the source data into the publication data model. The geo-processing task was packaged and documented and a handover to DELWP staff done so that they could execute and manage the process in the future as the source aquifer data changed.
The groundwater resource report itself was redeveloped using the Geocortex Essentials reporting capability. A simple Geocortex site was created which integrated with the publication aquifer data via an ArcGIS map service. The Geocortex site was for development purposes only – the groundwater resource report is accessed via a simple Vicmap API map on the DELWP web site and this user interface was not changed in this upgrade.
The groundwater resource report is highly dynamic in nature, due to the variable number of aquifers and aquitards that exist at any given location. In order to deliver the required format and design, the Geocortex report was customised using a Geocortex workflow and report scripting.
Spatial Vision then worked with DELWP technical staff to deploy the new report service into the enterprise MapShare environment and the report was integrated with the existing Vicmap API interface via the Geocortex REST interface.
