Available for viewing and sharing in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

Under contract to the Natural Communities Coalition (NCC), Aerial Information Systems (AIS) created an updated fine-scale vegetation map of portions of Orange County originally mapped in 2012-2015. AIS conducted field reconnaissance for this project in June 2023, and field verification in May 2024. California Native Plant Society (CNPS) under a separate contract with NCC was tasked to conduct the Accuracy Assessment.The mapping study area, consists of approximately 86,000 acres of open space and adjacent urban and agricultural lands, including habitat located in both the Central and Coastal Subregions of Orange County. Work was performed on the project between 2022 and 2025. The primary purpose of the project was to provide a good basis for trend analyses for long-term land management and conservation within the remaining natural lands of Orange County.CNPS under separate contract and in collaboration with CDFW VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The 2022 vegetation update used the same mapping classification as the 2012 project and is based on the floristic classification (AECOM, 2013), Manual of California Vegetation Second Edition (Sawyer et al., 2009), and the updated project floristic vegetation key (Buck-Diaz et al., 2025).The updated vegetation map was produced applying heads-up digitizing techniques using a baseline 1-meter resolution natural color digital image created in 2022 by the National Agricultural Imagery Program (NAIP), in conjunction with ancillary data and imagery sources. Map polygons are assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 1 acre for upland types and 0.5 acres for wetlands and other special types.Field reconnaissance and accuracy assessment enhanced map quality. There was a total of 100 mapping classes. The overall Accuracy Assessment score for the final vegetation map,at the Alliance and Group levels, is 85 percent.

CDFW BIOS GIS Dataset, Contact: Milan Mitrovich, Description: The habitat reserve system was created from the 1996 County of Orange (Central/Coastal) Natural Community Conservation Plan (NCCP) and Habitat Conservation Plan (HCP). A habitat reserve system was designed to support the subregional conservation strategy by creating long-term protection for multiple-habitat systems and multiple species.

This layer depicts the current zoning designation for property located in unincorporated Orange County. Zoning is implemented through Chapter 38 of the Orange County Code (see www.municode.com).

CDFW BIOS GIS Dataset, Contact: Milan Mitrovich, Description: Updated fine-scale regional vegetation map consistent with the California Department of Fish and Wildlife (CDFW) classification methodology and mapping standards for the Nature Reserve of Orange County (NROC).

This layer depicts the Future Land Use designation for all properties within unincorporated Orange County and those that have been annexed by a city but have not yet adopted a new Future Land Use designation. This layer is updated as amendments to the Comprehensive Policy Plan are processed in accordance with Chapter 163, Florida Statutes. It includes the current Future Land Use designation, the date of the Board of County Commissioners adoption hearing, the effective date for the amendment and amendment numbers.

CDFW BIOS GIS Dataset, Contact: Milan Mitrovich, Description: This vegetation is based upon the 1992 Jones and Stokes vegetation survey for Orange County California. This dataset has since been superseded by more recent vegetation surveys, but is does form the basis for historic files with Orange County Parks GIS.

A spatial representation of parcel history. This polygon feature class is created and maintained through the use of a customized tool for parcel maintenance management. As parcel splits and combinations create child parcels, the parent parcels are saved out to the parcel history feature class. Retired tax parcels have been maintained since 1998. Right of way and alley vacations are also maintained in this feature class. Vacations have been maintained since Spring, 2005. The key attributes include parcel identification number (KeyPIN) and the creation date (RevisionDate).

This is SCAG 2019 Regional Land Use dataset developed for the final 2024 Connect SoCal, the 2024-2050 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), including general plan land use, specific plan land use, zoning code, and existing land use at parcel-level (approximately five million parcels) for 197 local jurisdictions in the SCAG region.The regional land use dataset is developed (1) to aid in SCAG’s regional transportation planning, scenario planning and growth forecasting, (2) facilitate policy discussion on various planning issues, and (3) enhance information database to better serve SCAG member jurisdictions, research institutes, universities, developers, general public, etc. It is the most frequently and widely utilized SCAG geospatial data. From late 2019 to early 2020, SCAG staff obtained the 2019 parcel boundary GIS file and tax roll property information from county assessor’s offices. After months of data standardization and clean-up process, SCAG staff released the 2019 parcel boundary GIS files along with the 2019 Annual Land Use dataset in February 2021. In December 2021, SCAG staff successfully developed the preliminary dataset of the 2019 regional land use data and released the draft SCAG Data/Map Book in May 2022. The preliminary land use data was reviewed by local jurisdictions during the Local Data Exchange (LDX) process for Connect SoCal 2024. As a part of the final 2019 regional land use data development process, SCAG staff made every effort to review the local jurisdictions’ inputs and comments and incorporated any updates to the regional land use datasets. The products of this project has been used as one of the key elements for Connect SoCal 2024 plan development, growth forecasting, scenario planning, and SCAG’s policy discussion on various planning issues, as well as Connect SoCal key growth strategy analysis.Note: This dataset is intended for planning purposes only, and SCAG shall incur no responsibility or liability as to the completeness, currentness, or accuracy of this information.

This point feature class represents the center (not the true centroid) of each tax parcel polygon. The site address information is associated with each point that has a site address. Every point has a PIN (Parcel Identification Number) value. If there are multiple PINS associated with a particular tax parcel, the points are stacked on top of each other. If there are multiple site addresses associated with one PIN, these are stacked on top of each other as well. The points were created by a process that located the approximate center from the polygon feature class.
