Products


This section presents the existing geographic data, publications, news articles, the GAP home page, and meetings, symposia, and workshops that have resulted as GAP products. Not accounted for here is the effect GAP is having on building institutional relationships around information. Although the results from the GAP state-level partnerships are easily of equal value to more tangible products such as data, the products resulting from better integrated institutional relationships are more complex, more difficult to quantify, and require a great deal of time and effort.


Geographic Data

Digital spatial data files are the fundamental GAP material. The following are digital files that are currently available, listed by state and the primary point of access.
 
Arizona:
These data files are available via anonymous ftp at <aldo.srnr.arizona.edu>.
Natural terrestrial land cover
Vertebrate species distributions
Land ownership
Limited synthesis showing biodiversity by ownership category
 
Arkansas:
These data files are available at <http://www.cast.uark.edu/d.cast/new.catalog.html>.
Natural terrestrial land cover
Land ownership
Land management status

The Arkansas Center for Advanced Spatial Technology offers a remote map generation program using GAP and other data. Over the Internet, a user can select physical areas of the state and themes of interest, including, for example, habitat types, roads, military installations, state lands, or predicted species distributions. A map is then generated and provided to the user as a Postscript file.
