Title: Stormwater Pump Stations, San Mateo County Sea Level Rise Vulnerability Assessment Project Area, 2010
Contributors:- Point data
- 2019
- San Francisco Estuary Institute
- County of San Mateo Information Services Department
- California Regional Water Quality Control Board--San Francisco Bay Region
Summary: This dataset was created through the collaborative efforts of the San Francisco Estuary Institute (SFEI) and the Regional Water Quality Control Board (RWQCB) San Francisco Bay Region in the effort to identify the location and specific attributes of stormwater pump stations surrounding the San Francisco Bay under the jurisdiction of Phase 1 permittees and the California Department of Transportation. The RWQCB requested information from Phase 1 permittees during the fall of 2007 and SFEI organized the information into a database and this GIS shapefile. Attempts were made to standardize the data presented in this GIS into standard language and units for each attribute, however, no information offered by the permittees was deleted and differences are either noted within the dataset or the information was moved to the notes section. The RWQCB later requested similar information from Caltrans. Caltrans responded with information about 62 of their pump stations in the counties of Alameda, Contra Costa, Napa, San Mateo, and Santa Clara. This data was incorporated into the shapefile in March 2009. As of March 2010, the RWQCB plans to request the Phase 1 permittees to review the dataset to verify, update, and add additional information for each pump station as appropriate. This layer is part of the San Mateo County Sea Level Rise Vulnerability Assessment Project. These data are intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production.

Title: Impervious Areas, Cayuga Lake watershed, 2003
Contributors:- Polygon data
- 2008
Summary: This dataset delineates impervious surfaces within the Cayuga Lake Watershed. However, the current dataset is limited to Cayuga County. These polygons were digitized from aerial imagery from 2003, using a combination of automatic and manual methods. This geographic dataset was developed by the Cayuga Lake Watershed Network as part of a larger project, in conjunction with Dr. Douglas Haith and Cornell University, to model nutrient loading in the Cayuga Lake watershed. The model used is the Generalized Watershed Loading Function (Haith and Shoemaker, 1987). Haith, D.A. and L.L. Shoemaker, 1987. Generalized Watershed Loading Functions for Stream Flow Nutrients. Water Resources Bulletin, 23(3), pp. 471-478.

Title: Land Use and Land Cover, Cayuga Lake watershed, 2004
Contributors:- Polygon data
- 2006
Summary: The dataset depicts land use/cover in the Cayuga Lake Watershed. This geographic dataset was constructed using a multi-resource approach. To map small scale land uses, high resolution aerial imagery available from the New York State Digital OrthoimageryProgram (NYSDOP) was interpreted by a trained GIS analyst according to a multi-tiered classification scheme similar to that used by Tompkins County, New York to map land use in 1995. To map large scale land uses and land cover types, two sets of Landsat Thematic Mapper images were analyzed. One set was analyzed by the USDA National Agricultural Statistics Service Research and Development Division, and published as the Cropland Data Layer for the state of New York. To distinguish between different forest cover types, Landsat-5 TM images were radiometrically and geographically corrected, and analyzed using a supervised classification procedure. These separate layers were overlayed to produce the final vector layer. This geographic dataset was developed by the Cayuga Lake Watershed Network as part of a larger project, in conjunction with Dr. Douglas Haith and Cornell University, to model nutrient loading in the Cayuga Lake watershed. The model used is the Generalized Watershed Loading Function (Haith and Shoemaker, 1987). Haith, D.A. and L.L. Shoemaker, 1987. Generalized Watershed Loading Functions for Stream Flow Nutrients.
