Abstrac

To improve the performance in GIS-applications focused on recovering and analysis of the spatial data through spatial thematics, a Desktop GIS-Application has been designed. This application has been implemented using a software components technology, in particular Map Objects component. A spatial dynamic structure to index geographical objects is used into the GIS-application. Thus, it is possible to improve the performance for searching and processing spatial data. The system contains a geographical depository, which has been designed to store and handle the geo-information. The geographical data can be recovered by means of a particular spatial thematics using the R-tree structure. Several methods to make spatial analysis have been implemented into the desktop GIS-application. In this work, we consider the reuse of code and special techniques of the Geocomputation area to develop the tool.
