Web-based GIS on UNIX and NT Servers
Presently the University Of Pittsburgh Department of Geology and Planetary Science actively supports training in Geographical Information Systems. This includes graduate training and research such as presented in GIS analysis and stress modeling of tectonics blocks at Cape Kamchatka, Russia, 2000, M.S. thesis Sarah Zimmerman, 357 pp. (CDROM included), A Time Dependent Model of Radiative and conductive Thermal Energy Transport in Planetary Regoliths with Applications to the Moon, Mercury, and Io, 2000, Ph.D. thesis, Amy Synder Hale, 163 pp., and The General Integrative Watershed Model (GIW): A GIS Based, Landscape Ecology Approach to Large River Environmental Management, 1998, Ph.D. thesis, R. Kyshakevych, 261 pp. In addition the department presently supports laboratories actively involved in mapping, Remote Sensing and GIS, these include the Geographical Information Systems/Remote Sensing Lab (http://www.geology.pitt.edu), the Planetary Mapping Lab (http://viking.eps.pitt.edu), and the Image Visualization, Infrared Spectroscopy (IVIS) and Global Positioning System Lab (http://ivis.eps.pitt.edu). Software and hardware within the GIS/RS Laboratory include 10 Ultra 10 dual OS systems (SOLARIS/NT) workstations, SPARC Ultra 2 Server-2 Processor 1.3Gigabyte RAM, 400 Gigabyte disk array, Large Format Plotter/Printer, Misc. I/O Hardware, ESRI Arc/Info 8.0.2 (TIN/GRID/NETWORK/COGO/ArcScan), ESRI Arcview 3.2 (AVSpatial/AVNetwork/AV3D; www.esri.com), ERDAS Imagine 8.4 (All modules, including Virtual GIS 8.4; www.erdas.com) , ERMAPPER 6.0 (Including most modules; www.ermapper.com), RSI IDL Envi_rt, Alaska SAR Facility (All tools, including restricted Radar Interferometry processing modules), World Construction Set (5) www.3dnature.com. One collaborative project presently coming on-line is the Monitoring Former Soviet Union (FSU) cities using NASA ASTER Data. Targeted cities include Moscow, Novosibirsk, St. Petersburg, Tashkent, Omsk, Irkutsk, Yakutsk, and Petropavlovsk. Our decision to utilize web-based presentation of these data and analysis was made on the basis of the positive features of world-viewable geodatasets, instantaneous access, easy international collaboration and geodataset uploading/downloading, web master/mistress control of all spatial and tabular operations applied to data, monitoring of usage, hits and user initiated operations. Significant negative elements to the web-approach include corporate and personal liability, geodata accuracy, metadata, geodata history and support, multi-language support, copyright, and network security (tips on breaking into servers are ubiquitous). In this poster software and security responses to these concerns are presented in detail.
