The technical foundation of the Center is a 155Mbps ATM network connecting over 30 workstations and an SGI Origin 200 GIGAChannel server housing the mass storage devices and applications software. A second RAID has recently been added to the system, bringing the total amount of disk space to 390 Gb. Workstations are installed and accessed remotely in each department, but are supported and administered centrally for a seamless virtual research platform.
The Center facilities also include a wide array of input-output devices including digitizers, image scanners, color scanners, color laser printer, and large format color plotters, as well as an array of data storage devices.
A large suite of applications software provides state-of-the-art capabilities for image processing, GIS mapping and analysis, modeling, statistical analysis, and visualization. Access to the following major software systems is provided by ERSAC:
ArcView and ArcInfo (http://www.esri.com)
A University site license for ArcView and ArcInfo and several other ESRI GIS modules provide the primary GIS analysis and modeling tools for ERSAC users.
ERDAS IMAGINE (http://www.erdas.com)
ERSAC has a site license for ERDAS IMAGINE (30 seats) and other modules (Subpixel Classifier, OrthoMax, MapSheets, Radar and Virtual GIS).
S+SpatialStats (http://www.splus.mathsoft.com)
A comprehensive, object-oriented program designed for statistical analysis of spatial data.
MySQL (http://www.mysql.com)
Relational database management system that works directly with ArcInfo. Also can be used for creating databases of remote sensing imagery and other map data.
Khoros
Software system from the University of New Mexico with a wide array of algorithms for image processing and GIS.
