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

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. ……

Goal

Desired Outcome

  • Consistent user experience across library resources.

 • Seamless searching and access to public and proprietary data.

 • Guidance and experience on developing metadata strategies for

spatial information (traditional maps vs. digital collections). • Web mapping services
