Spatial Analysis Lab
The Spatial Analysis Lab, or SAL, is one of the landmarks of the School. The SAL lab uses many high end GIS applications, such as ESRI ArcInfo and Leica Geosystems' Erdas Imagine, to analyze and interpret spatial data, like aerial photography or Remote Sensing infrared images.
The SAL utilizes Sun UNIX workstations, Windows workstations and Dell, Inc. PowerEdge servers to both host and digitize terabytes of spatial data. Also, much like Fayeteville's Center for Advanced Spatial Technology, the SAL lab hosts a digital database for Arkansas oriented spatial data, such as land use or soil types. This data is available from an easily navigated web interface. SAL also is home to two publicly accessible survey data correction servers. The first is a constantly running mapping grade GPS base station for use in differential correction of GPS data within 300 miles of Monticello. The second is a survey grade GPS base station that is part of the National Geodetic Survey's CORS (Continuously Operating Reference Station) network. The CORS station has a definitely known geodetic position and is used with other CORS stations for sub-meter GPS differential correction through the OPUS (Online Positioning User Service) service.

Famous quotes containing the word analysis:
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
