Özet:

Turkish Topographic Vector Database (TOPOVT) is a 3D vector database comprising 1:25.000 scale or higher resolution topographic features, contours representing the topography and geographic names. TOPOVT is the basic geographic data source for our country mapping and base for GIS applications covering whole Turkey. So far data collection for TOPOVT has been carried out by General Command of Mapping. Updating of TOPOVT is a continuous process and goes on by annual planning on regional base. Geospatial data collection, either in the office or in the field, is a hard, costly and time consuming process. Using the existing geospatial data will be a suitable solution for get rid of all these expenses. Governmental institutions and municipalities have their own GIS and collect and update these geospatial data according to their needs. With a close look, these data are similar to TOPOVT data or with a little effort can be converted to TOPOVT model. TOPOVT Real Time Updating System was designed to provide all governmental institutions and municipalities producing and using geographic information via internet to update and easily access to TOPOVT. TOPOVT Real Time Updating System has been realized to avoid duplicate geographic data production countrywide and reflect the changes in topography to TOPOVT in real time or near real time. This system will enable governmental institutions and municipalities to update TOPOVT in their service areas according to their job definition without needing another software thus providing the TOPOVT users to make use of the up-to-date data. By this system, all the governmental institutions needing topographic database for their applications will easily reach TOPOVT, make use of the data in their field works and present the data they produced to country use. Also, by avoiding the duplicate geographic data production, national sources will be utilized economically and effectively.
