Provides numeric and spatial data services like... Data Visualization Geographic Information Systems (GIS) Research Consultation Quantitative Methods
Why put GIS in the library? Connect technology to data collections New Methods of Information Analysis Interdisciplinary Information hub Support Teaching and Research Access to data and geographic information Guidance/education on how to use software, tools, etc.
What kind of data goes into a Geospatial Collection? • Basemap data (transportation networks, water, etc) • Aerial photography • Datasets • Digitized copies of physical maps in library collection
Basemaps – data combined with the intention to create a starting point for more detailed mapping. Usually include the following themes: - Transportation layer - Land cover - Boundaries - Elevation - Hydrography
Administrative Boundaries Points of Interest Transportation Networks Elevation Imagery Hydrography

Content Standard for Digital Geospatial Metadata (CSDGM) • Purpose: These files were developed to enable a user to see the geographic component from the 2000 Census. They can be used to join demographic data from the 1990 census for use in a geographic information system.” • Process Description: Defense Mapping Agency processing: The main source material for the WVS was the DMA's Digital Landmass Blanking (DLMB) data which was derived primarily from the Joint Operations Graphics and coastal nautical charts produced by DMA. The DLMB data consists of a land/water flag file on a 3 by 3 arc-second interval grid. This raster data set was converted into vector form to create the WVS. For areas of the world not covered by the DLMB data (e.g. the Arctic and Antarctic), the shoreline was taken from the best available hard copy sources at a preferred scale of 1:250000. …… FGDC
