Abstract

The paper presents a computer based system architecture for generalization of buildings. Obtaining and updating georeferenced data is the highest cost item in building and maintenance of any GIS system. In these systems, data on buildings are featured with the highest dynamics of changes, which requires constant updating and translates into significant costs of the system maintenance. A software to automate the process of acquiring and updating the data base of buildings and their generalization, is the main objective of the proposed system.
As a result of an analysis, it was decided to use a system architecture based on a geo-portal software. The technical solutions are based on Windows 2008 R2 server and the Web server runs on Microsoft IIS 7.0. ArcGIS Server database with PostGIS 2.0.1. will be used to build the software of the geoportal. The software for the generalization of the system will be made in Microsoft Visual Studio 2010 in C # using ArcGIS Application Framework Developer for Microsoft .NET Framework.

Keywords:
