Title: Hopkinton, Massachusetts, ca. 1970 (Raster Image)
Contributors:- Raster data
- 2013
Summary: This layer is a georeferenced raster image of the historic paper map entitled: Hopkinton, prepared for the town of Hopkinton by the Massachusetts Department of Community Affairs. It was published by the Deptartment of Community Affairs ca. 1970. Scale ca. 1:19,000. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also public lands, location map, and magnetic declination diagram. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

Title: Groundwater Elevation Change Color Ramp, California, Spring 2015 to Spring 2016
Contributors:- Raster data
- 2016
Summary: This raster dataset (GeoTIFF) represents groundwater elevation in California using a color ramp. These data represent groundwater changes between spring 2015 and spring 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 color ramp values because of the smoothing process. 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 Color Ramp, California, Spring 2015 to Spring 2016. California Department of Water Resources. Available at: http://purl.stanford.edu/gt506qf5033. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

Title: Groundwater Elevation Change, California, Spring 2013 to Spring 2016
Contributors:- Point data
- 2016
Summary: This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between spring 2013 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 2013 to Spring 2016. California Department of Water Resources. Available at: http://purl.stanford.edu/tt235rq6188.

Title: Groundwater Elevation Contours, California, Spring 2012
Contributors:- Line data
- 2016
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.

Title: Groundwater Depth Contours, California, Spring 2014
Contributors:- Line data
- 2016
Summary: This line shapefile represents the depth to groundwater below the ground surface in California during the Spring of 2014. 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).
