The software (CD-ROM) selected and purchased, as per the project proposal, for the purpose of immediate implementation of GIS applications in various disciplines, with emphasis on environmental engineering, was the professional ArcView GIS software obtained from ESRI (Environmental Systems Research Institute), the worldwide leading developer of GIS software. The acquisition of available data is a very important aspect for the use of GIS systems. Typically, it is not feasible or desirable to create an entire map from scratch. In many cases, maps are available from local, state or federal governments. ESRI, publisher of ArcView, publishes a list of www sites using its products to provide geographic information in its quarterly magazine, ESRI ARC News. They also sell a CD-ROM containing every street in the US with geocoded addresses. These are adequate for the purpose of preparing modules/examples of GIS applications in various disciplines. All software was installed and tested in the Gateway Multimedia Room and in various PC’s, including the Gateway computer design center.
