This software developed as two module; Desktop and Internet Module. Desktop module is developed for the governmental personel. Internet module is developed to access the parcel based official documents on internet. The purpose of generating this prototype is to transmit the spatial government documents (cadastral plans, construction permission plans, land usage plans, application plans, etc.) to related person and agencies in electronic environment using e-government applications.  

In parcel based webGIS applications, considering that potential users will be ordinary people with limited computer knowledge, it is aimed to prepare the required documents automatically, as a user enters the minimum data (parcel number).

 This application is generated using fat client architecture and it is a client based application. Once logging in to the system, an ActiveX component is downloaded and added into the user’s browser. This component improves the browser’s functions and transforms it to software, which meets the objectives of the system. The component, written in Visual Basic 6.0 platform, is interactive software.

 When a user enters the block and parcel number to display its document; firstly, this number is transmitted to the server; secondly, Visual Basic scripts in Active Server Pages starts running; then, information about this parcel are pulled out from the data base; and finally, this information are sent back to the user’s computer. The software added into the user’s browser analyses and processes the spatial and non-spatial data and then displays them on the computer screen in the form of an official document (Figure 1). The user can scale the graphical data and also can have it as a hard copy by printing it out.

 Vector based spatial data are sent from the server to the client. The data are saved in the data base of Microsoft Access. As it is aimed by the system, coordinate data as well as the topological information is saved in the data base. The document example generated by webGIS software are indicated in Figure 2.
