Title: NRPI
Contributors:- Point data
- 2005
Summary: A Collaborative Effort between the California Biodiversity Council and the University of California at Davis Information Center for the Environment. The signatories of the California Biodiversity Council joined forces to gather information on thousands of conservation, mitigation and restoration projects being developed and implemented throughout California. The result, the Natural Resource Project Inventory (NRPI), has become a comprehensive electronic database searchable on the Internet. NRPI is an expansion of previous inventories including 1) the Watershed Projects Inventory (WPI), 2) the California Ecological Restoration Projects Inventory (CERPI), and 3) the California Noxious Weed Control Projects Inventory.

Summary: The data for this polygon shapefile was collected and created with the same camera system and processing software as the 2008 survey. Surface and subsurface kelp canopy imagery was collected and processed with separate classification schemes. The shapefile was created from Digital Multi-Spectral Camera image files. The data was collected and processed by Ocean Imaging under contract by the Resources Legacy Fund Foundation (RLFF) for the Marine Protected Areas Monitoring Enterprise. This dataset represents the 2009 aerial kelp survey. The imagery was collected on October 01, 2009 from an altitude of 12,500 feet. Surveys were planned to coincide with periods of minimal change between high and low tides to avoid strong tidal induced currents. This coverage is complete, although the user should note any omissions. The data are projected in California Teale Albers using North American Datum 1983. File reindexed to match CDFW kelp administrative kelp bed boundaries modified by changes to California Code of Regulations, Title 14, Section 165, effective April 1, 2014. This dataset was developed for the Marine Protected Areas Monitoring Enterprise to assess the extent of kelp canopy resources along the North Central California coast (Pigeon Point to Alder Creek).

- 2013
Summary: The California Air Resources Board (ARB) GIS Maps and Data set is a collection of vector shapefiles, which contain data related to air quality management and monitoring within California. The ARB compiles the state's emissions inventory and performs air quality and emissions inventory special studies. This dataset contains ambiant air quality data and provides maps of areas that violate the state and national standards. ARB compiles these data in an effort to comply with standards set forth in the U.S. Clean Air Act. System requirements: Geographic Information Systems (GIS) software that reads ESRI shapefile format.

Title: Urban, Agricultural, Industrial, and Natural Land, San Mateo County Sea Level Rise Vulnerability Assessment Project, 2012
Contributors:- Polygon data
- 2019
Summary: This polygon shapefile represents a land use survey of San Mateo County conducted by the California Department of Water Resources, North Central Regional Office staff. The field work for this survey was conducted during June 2012 by staff visiting each field and noting what was grown. Land use field boundaries were digitized using ArcGIS 10.0 with 2010 National Agriculture Imagery Program (NAIP) one-meter imagery as the base. Field boundaries were reviewed and updated using 2012 NAIP imagery when it became available. Field boundaries were not drawn to represent legal parcel (ownership) boundaries, or meant to be used as parcel boundaries. Images and land use boundaries were loaded onto laptop computers that were used as the field data collection tools. GPS units connected to the laptops were used to confirm surveyor's location with respect to the fields. Staff took these laptops into the field and virtually all the areas were visited to positively identify the land use. Land use codes were digitized in the field on laptop computers using ESRI ArcMAP software, version 10.0. This layer is part of the San Mateo County Sea Level Rise Vulnerability Assessment Project.
