Abstract


GIS software provides a powerful tool for the analysis of space-related information processing and visualization , component-based GIS integrated application development has become the mainstream of the current GIS application software development . Application background papers to specific projects , GIS integrated development in data acquisition , processing and display are three main steps to the main line on some of the key technical problems encountered during GIS integration development by these analyzes the problems and proposed solutions corresponding program , and in the actual application , and achieved good results . Primitive generation and load information visualization in GIS applications based on paper first analyzes the primitive generation and load in GIS , and on this basis to focus on massive primitive way . Regional statistical analysis is an important function of the application of GIS , Statistical Analysis for the regular grid on the irregular region , the paper presents a rectangular partition algorithm based on the projection and the Transverse Mercator projection grid division and grid statistical analysis , the paper also describes the realization of thematic maps of statistical analysis methods . GIS application system has been more and more concerned about the location-based services (LBS) . Positioning for GPS, mobile phone and fixed-line telephone , paper, based on the specific engineering practice through the use of different communication mechanisms , communication protocols , and positioning mode , respectively elaborated a concrete realization of various positioning systems . The contour generation GIS system is very extensive, contour drawing , the paper first analyzes based on the rules of the grid data grid generation algorithm based on discrete data triangulated irregular network (TIN) generation algorithm , and then discuss regular grid and contour triangulated irregular network generation algorithm , and rule-based contour map of the rectangular grid drawing in engineering practice , satisfied .
