Summary: This datalayer contains lines representing Massachusetts watershed boundaries (see also the Watersheds (Polygons) datalayer). MassGIS has produced a statewide digital datalayer of the 32 major watersheds covering Massachusetts as defined by the USGS Water Resources Division and the MA Water Resources Commission. The datalayer is called Watersheds. Unlike the Major Drainage Basins layer, the watersheds in this layer extend beyond the state boundary to include the full extent of either the full watershed or a full USGS sub-basin.

Title: Urban, Agricultural, Industrial, and Natural Land, San Mateo County Sea Level Rise Vulnerability Assessment Project, 2012
- Polygon data
- 2019
- Not owned by MIT (Owned by Stanford)
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. 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: Groundwater Elevation Contours, California, Spring 2012
- Line data
- 2016
- Not owned by MIT (Owned by Stanford)
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).

- Not owned by MIT (Owned by Stanford)
Summary: This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between spring 2006 and spring 2016.
