Critical Data for Sonoma County
The publicly available datasets produced by this program (see full list here) – including countywide LiDAR data and a fine scale vegetation and habitat map – will provide an accurate, up-to-date inventory of the county’s landscape features, ecological communities and habitats. These foundational data sets are key to facilitating good planning and management for watershed protection, flood control, fire and fuels management and wildlife habitat conservation. These data are also critical to assessing climate mitigation and adaptation strategies and benefits provided by the landscape, such as the amount of carbon sequestration in forests or the degree to which riparian areas, floodplains, and coastal habitats may buffer extreme weather events.
The District, the Water Agency, and their partners have worked together to procure the necessary funding for all program elements including the vegetation and habitat map, LiDAR data, and a suite of additional next-generation data products collected in fall, 2013 including high resolution topography, building outlines, roads, and high resolution aerial photography. State and federal partners are responsible for funding approximately 58% of the program, with the remaining 42% coming from Sonoma County partners. The core funding for the LiDAR data products comes from a NASA grant to the University of Maryland. For more information on the NASA grant, see our press release.
What is the Veg Map?
The District, the Water Agency and their partners will develop a classification of the county’s vegetation types and physical features, analyze the LiDAR data and high resolution aerial imagery using human interpreters and computer algorithms, and verify vegetation characteristics in the field. The result will be the creation of a fine scale vegetation and habitat map for the entire county (click here for more on methods). LiDAR data will increase vegetation map accuracy and provide three dimensional data regarding the built environment, forest structure, and landscape features such as streams and wetlands – all of which support multiple applications for:
- natural resource planning
- land conservation
- sustainable community and climate protection planning
- public works projects
- hydrologic evaluations
- watershed assessments and planning
- disaster preparedness
Tukman Geospatial LLC, a Sonoma County-based geospatial technology firm with specific expertise in vegetation mapping, serves as the primary contractor for mapping and data collection. Supporting Tukman Geospatial are Kass Green and Associates, Watershed Sciences, Inc., Prunuske Chatham, Inc., the California Native Plant Society (CNPS), Dr. Jarlath O’Neil- Dunne (University of Vermont), and Kruse Imaging. The program has an array of advisers, including the Vegetation Mapping and Remote Sensing Advisory Committee, which advises the mapping team on state-of-the art mapping techniques and methods.
The program, which began in 2012, will last five years. Field work to develop a vegetation classification for Sonoma County was conducted in summer and fall 2013 and will continue throughout spring 2014. LiDAR and aerial photography were acquired in late 2013 and are now available; vegetation and habitat mapping is now underway. Expected delivery dates for map and data products are shown in the full list of data products.
The Vegetation Mapping and Remote Sensing Advisory Committee, comprised of 15 experts in remote sensing, GIS, vegetation mapping, and technology, advises the mapping team on technical issues and the keeps the team up to speed on the newest mapping methods and technologies. For more information on the technical advisory committee – including a list of members – click here.
The Local Ecology and Botany Group, made up of about 35 experts in ecology, botany, and land management, provides expert local botanical and ecological insight to help make the most comprehensive, accurate, and useful map possible.
