OIT-UCSB 09/25/2006 Spatial Organizing Concept Searching for a data object, using an “earth” location, adds a powerful search dimension to traditional library cataloging methods. Spatial coordinates are a universal language. During searching, this search method overcomes any cultural or language anomalies that occur in catalog records. Data organization, whether terrestrial, planetary, or the human body via coordinate systems, guarantees a “completeness” of search results. “I want all available information about this location” “I want all available information about this location”

OIT-UCSB 09/25/2006 Description of NGDA’s Web Data Browser (Beta)

OIT-UCSB 09/25/2006 Figure 1. Upon loading the NGDA collection browser Landsat imagery over the US is loaded by default

OIT-UCSB 09/25/2006 Figure 2. After switching to the DRG historical map collection, a orange "cluster button" indicates that there are a number of maps of California available to view at a higher zoom level. Pressing the cluster button recenters the map and redisplays the atlas at higher resolution.

OIT-UCSB 09/25/2006 Figure 3. The same collection at a higher zoom level. The maps are still too small to view at this distance, but we have more detailed information regarding the range of the collection (e.g., more maps over central and southern California than over the Nevada California border).

OIT-UCSB 09/25/2006 Figure 4. At a higher zoom level we can see the DRG maps aligned geospatially and tiled over Santa Barbara.

OIT-UCSB 09/25/2006 Figure 5. After two browse panels have been opened for more detailed inspection/comparison. Once a browse panel is opened, a user may download (if permitted) the larger full-resolution map image and project data, or choose to see the full detail of the catalog records for a particular item.
