Client: National Parks and Wildlife Service, NSW
The NSW National Parks and Wildlife Service (NPWS) directly manages 5.8 million hectares of NSW. NPWS is seeking to create a new Land Information System (LIS) to assist management of this extensive portfolio. The LIS would comprise an integrated geospatial and textual centralised database that could be accessed remotely by users across the state.
NPWS had largely settled on the software components to comprise the LIS, which included ESRI’s ArcSDE, ArcGIS and ArcIMS. They had also identified different user groups for the LIS, including a small group of spatial editors, a larger group of textual editors and the largest group of view-only query users. Each of these user groups would access the LIS via a range of different interfaces and tools, all of which must provide a consistent and coordinated view of the underlying spatial and textual data.
Spatial Vision was contracted by NPWS to assist in the selection of a suitable architecture for this complex requirement. The architecture was required to integrate all of the software and data requirements, support a variety of user interface applications and work effectively in the NPWS IT environment, especially in terms of network impact and security. The architecture would also be required to support future NPWS applications.
As part of the design process, Spatial Vision facilitated a workshop of key stakeholders to review system requirements and various technical options. The workshop also addressed complex issues such as external access to ArcSDE versioned datasets and automated spatial overlay processes to derive relationships. For example, the versioned datasets would hold details of parcels of land proposed to be part of a new reserve. The spatial overlay would be used to automatically flag potential conflicts for a proposed reserve. From the workshop outcomes and further consultation, Spatial Vision documented the architecture that best met NPWS’s requirements for the new LIS and a platform for future spatial development.
