2026 WA GIS Conference: Full Schedule

9:00am PDT

Using Native SQL Geometry for Cloud-Ready, Lightning-Fast Overlays

Thursday May 21, 2026 9:00am - 9:30am PDT

Serving high volume, complex reports that require querying dozens of GIS layers for a single parcel is a major performance hurdle. Our Districts and Development Conditions Report simultaneously queries nearly 60 layers, which has the potential to severely impact application performance. This session details the architectural overhaul we implemented to overcome this challenge without changing the core query structure. Our key improvements were optimizing the underlying data storage by moving to the native SQL Server geometry type and using spatial SQL queries.
