The UC Davis Library’s Geospatial Data Specialist provides Drop-In Hours on Mondays from 1:30-3:00 in the DataLab Classroom – room 360 in Shields Library. This time is set aside for any and all questions about spatial data, from simple to complex. Library patrons are always welcome to make an appointment for another time with the Geospatial Data Specialist, Michele Tobias, to discuss spatial data.
UC Davis affiliates can sign up for email lists through the UC Davis Information & Educational Technology’s Sympa list serve manager. The “Geospatial” email list is a widely-used list for UC Davis faculty, students, staff, and local community members who work with any type of geospatial data. The list can be used for announcements or questions.
The geospatial industry has a number of established, well-respected, and long running free and open source projects that may suit the needs of researchers and students. The Open Source Geospatial Foundation oversees many of these projects, including QGIS (which runs on Mac, Linux, and Windows).
Esri’s ArcGIS suite of software is available to any UC Davis affiliate. Information on product availability, and licensing guides can be found at http://arcgis.ucdavis.edu
The lower level of Shields Library has one GIS workstation that UC Davis students, faculty, researchers, and other staff may to use for a maximum of two hours per day. The workstation room is located near, but outside the Map Room and is open the same hours as the Library. The workstation has the full suite of ArcGIS 10 software (available to campus affiliates) and QGIS 3 (available to anyone).
An 11″ x 17″ color scanner is available for maps and aerial photography.
- GIS software and data licensed by the library may not be used for commercial purposes.
- Software and spatial data may be licensed and subject to restrictions on who can use it and how it can be used. We provide GIS users with public domain data and any other data and software that we can under the terms of the licenses.
- It is advisable to save your data and project files to portable media.
The USGS Earth Explorer is USGS tool for querying and ordering raster geospatial data including satellite images, aerial photographs, and cartographic products. Log in as a guest or as a registered user. Registered users have access to more features than guests do. If you plan on using Earth Explorer frequently, you may wish to register.
The Geographic Names Information System (GNIS)is the official repository of the United States of America’s domestic geographic names data. The GNIS contains information about physical and cultural geographic features of all types in the United States, associated areas, and Antarctica, current and historical, but not including roads and highways. The database holds the Federally recognized name of each feature and defines the feature location by state, county, USGS topographic map, and geographic coordinates. Other attributes include names or spellings other than the official name, feature designations, feature classification, historical and descriptive information, and for some categories the geometric boundaries.
