Orange County California is on the move. The County is planning and managing one of the most modern and innovative GIS implementations across the country. Through their strategic vision and leadership, the County operates a robust survey control system, a modern parcel fabric, both outdoor and indoor GIS at John Wayne Airport and provides a wealth of services that supports sustainable and resilient workflows for their community’s health.
The County of Orange serves 34 cities in the Southern California region. GIS became a vital component of mapping and data management in Orange County more than 35 years ago through the OC Survey team. In the early 1990s, the County established a Countywide Survey Control Network made up of more than 2,800 GPS monuments, adopting GIS, CAD and GPS to become a leader in survey and mapping. The County has continued its growth since then, including the addition of more than 5,700 subdivisions and 114,000 new parcels.
Orange County uses ArcGIS as a foundation for its parcel fabric, imagery, LiDAR and digital infrastructure, all built on accurate survey control. The OC Survey GIS team developed a self-service map submission application using the ArcGIS API for JavaScript and Autodesk Platform Services that surveyors can use to complete a digital check of their maps, streamlining the county review process, providing real-time validation and reducing costs.
The County developed an add-in tool for ArcGIS Pro to adjust and make changes to their parcel fabric. When the land moves due to an earthquake, they can quickly shift all of their parcels to the adjusted control points, simplifying workflows for parcel adjustments and ensuring the County’s parcel fabric is precise and accurate.
Orange County manages John Wayne International Airport (SNA), using GIS applications to streamline airside, landside and inside functions for the airport.
After a wet winter in Southern California, the County found a roof leak in one of the terminals at SNA. Orange County used a combination of 2D terminal floor plans, 3D models, Indoor GIS and drone imagery to identify where the water was pooling and communicate with the maintenance team for repairs.
The GIS team at Orange County is motivated to explore and implement new ideas and technologies that can move them forward. Their success is due to its many partnerships across the public and private sectors, its core principles of Be Curious, Be Engaged and Be Inspired, supportive leadership and specialized staff, and continued investment in modernizing GIS workflows.
