The tools they used were ArchView, and ArcGIS from a company called ESRI. ESRI is the industry leader in GIS, just as Autodesk is in Architectural CAD.<BR/><BR/>GIS is higlhy dependant on using external reference files. The difference is that these files are not created in-house, but are ''called'' from internet sources, like the U.S. Census Beaureau.<BR/><BR/>Items that are created buy the developer include north arrows, and various symbols. They have the ability to create lines and polygons to hatch, show propose roads and utilities etc. Existing roads are downloaded from a national street index maintained by some federal agency. I forget whether it is the Census Beaureau, Dept of Commerce, or some other.<BR/><BR/>Developers can also create controls for end users to manipulate the data. Ever use MapQuest?IgorTheCathttps://www.blogger.com/profile/00330322277192124934noreply@blogger.com
