Welcome to the Harvard Geospatial Library

Search, discover, preview, and retrieve geospatial data from multiple repositories

Search

There are two ways to search for data. The two methods can be used individually or combined for more effective search

  • Use basic or advanced search
  • Interact with the map to search for data by relevant geographic extent

Interacting with the map

  • Interacting with the map will perform a search for relevant data
  • Enter a place in the Find Place field to zoom to a location
  • Click the Zoom or Pan tool and drag the map with the mouse
  • Double-click to zoom in on an area
  • Hold down shift and click-drag a box to zoom to an area
  • Click on Basemap to set the background layer to OpenStreetMap, Google Maps, etc.

Preview

The Harvard Geospatial Library is the main repository a catalog for geospatial data in the Harvard University Libraries. Originally developed in 2001 with an internal Library Digital Initiative grant as well as the generous support of the Rasmussen Foundation, HGL is now part of a broader multi-institutional project. The flagship site of this effort is Geodata@Tufts.

GeoData@Tufts is developed and maintained by Tufts University Information Technology. Tufts is leading the development in collaboration with Harvard of this open source, federated web application to rapidly discover, preview, and retrieve geospatial data from multiple repositories. GeoData@Tufts combines an intuitive, map-based search interface along with traditional text-based metadata search tools for rapid data discovery and for use in teaching, learning, and research.

GeoData@Tufts is part of The Open Geoportal. The Open Geoportal is a consortium comprised of contributions of several universities and organizations to help facilitate the discovery and acquisition of geospatial data across many organizations and platforms. Current partners include: Harvard, MIT, MassGIS, Princeton, Columbia, Stanford, UC Berkeley, UCLA, Yale, and UConn. Built on open source technology, The Open Geoportal provides organizations the opportunity to share thousands of geospatial data layers, maps, metadata, and development resources through a single common interface.
