  14. Title: Urban, Agricultural, Industrial, and Natural Land, San Mateo County Sea Level Rise Vulnerability Assessment Project, 2012

    Contributors:

    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.

  17. Title: Groundwater Elevation Contours, California, Spring 2012

    Contributors:

    Summary: This line shapefile represents groundwater elevation in California for spring 2012. This layer is a smoothed approximation of the groundwater level 'surface' based on the measurement data. The measurement values may not exactly match the contour values because of the smoothing process. Water level measurements are selected based on measurement data and well construction information (where available) and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers. This layer is intended to be used as a compliment to data, reports, and other information provided by the California Groundwater Information Center. California Department of Water Resources. (2016). Groundwater Elevation Contours, California, Spring 2012. California Department of Water Resources. Available at: http://purl.stanford.edu/dw932vj1291.

  18. Title: Groundwater Elevation Change, California, Spring 2006 to Spring 2016

    Contributors:

    Summary: This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between spring 2006 and spring 2016. Each point shows the calculated difference between the measured groundwater levels from the time period. The change in groundwater level is plotted on the map only if a measurement exists in both time periods as well. The colored points in the measurements layer show the location of all wells where the groundwater level change is determined. This layer is intended to be used as a compliment to data, reports, and other information provided by the California Groundwater Information Center. California Department of Water Resources. (2016). Groundwater Elevation Change, California, Spring 2006 to Spring 2016. California Department of Water Resources. Available at: http://purl.stanford.edu/bm205gp3500.

  19. Title: Groundwater Depth Contours, California, Spring 2016

    Contributors:

    Summary: This line shapefile represents the depth to groundwater below the ground surface in California during the spring of 2016. This layer is a smoothed approximation of the groundwater level 'surface' based on the measurement data. The measurement values may not exactly match the contour values because of the contour smoothing process. Depth information is represented in feet below the ground surface. Water level measurements are selected based on measurement data and well construction information (where available) and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers. This layer is intended to be used as a compliment to data, reports, and other information provided by the California Groundwater Information Center. California Department of Water Resources. (2016).

    Contributors:

    Summary: This raster dataset (GeoTIFF) represents groundwater elevation in California for spring 2012 using a color ramp. This layer is a smoothed approximation of the groundwater level 'surface' based on the measurement data. The measurement values may not exactly match the contour values because of the smoothing process. Water level measurements are selected based on measurement data and well construction information (where available) and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers. This layer is intended to be used as a compliment to data, reports, and other information provided by the California Groundwater Information Center. California Department of Water Resources. (2016).
