GIS Public Access <br />Using Extranel Technology <br /> <br />Cabarrus County <br />North Carolina <br /> <br />3. Description of the Program <br /> <br />GIS began the search for a cost effective Public Access system in 1995. Expensive client <br />licenses and hardware requirements eliminated the customized ARCINFO application. A <br />customized Arcview solution was less expensive to implement but users were still <br />required to purchase proprietary client software. Several Arcview applications were <br />developed for the Land Records and Revaluation depaxhnents. We found that the <br />Arcview applications can be a valuable tool for our trained departmental users but they <br />are too technical for general public use. <br /> <br />In February of 1997 we explored ESRI's Map Objects and Intemet Map Server and found <br />it was a cost effective solution that could be implemented using our existing Internet <br />connection. This solution does not require users to have a proprietary client software <br />license installed on their workstation. It only requires a web browser and local access to <br />the Governmental Center network or an Interact connection. Most users with Internet <br />access are already familiar with the browser interface used to access the map server <br />application. <br /> <br />Our GIS staff immediately began plans for the project deployment. Unfortunately we <br />could not schedule Visual Basic training until May 1997 and Map Object training until <br />September 1997. Budgeted money for the GIS Public Access had already been carried <br />over two fiscal years. In order to implement GIS Public Access before the end of the <br />1997 fiscal year, a consultant was hired to write the Map Object Visual Basic code. <br /> <br />Ron Vincent of New World Mapping was engaged to write the Visual Basic and Map <br />Objects code. During the week of June 16-20 1997, Ron used specifications provided by <br />the county GIS staff to write the application. GIS staff also manipulated data GIS <br />structures and established the data flow between the mainfxame, RS/6000, and the PC <br />Internet Map Server. IS systems staff provided the HTML/Internet coding and design for <br />the fmal page layout. <br /> <br />The initial objective of the GIS Public Access was to give users the capability to select, <br />display, and print a parcel map. During the development phase we realized much more <br />information associated with a parcel of land could and should be displayed. Land <br />Records and Revaluation staff helped GIS identify information commonly requested by <br />the public. IS programming staff wrote an application to extract this information from <br />the mainframe database. The GIS staff then used the parcel identification number to link <br />the tabular data from the mainframe data base to the graphical tax map. <br /> <br />WWW.CO.CABARRUS.NC.US <br /> <br /> <br />
