This chapter is devoted to aerospace images and raster topographic maps processing and recognition methods application to create and update vector maps and digital elevation models (DEMs), that form geoinformation basis to solve computational problems (for instance, relocation routes multicriterial construction) and visualize terrain.

Methods for objects with different geometric shapes detection in set up by user calibration points on aerospace images are considered. The method provides automatic detection of the object’s parameters (for instance, rectangle’s position, orientation, and aspect ratio). A method for buildings’ and constructions’ projection to the basement, providing their true geographic positions definition, and a method for objects’ shades detection, designed to calculate their heights over the underlying surface, are described. Experimental investigations of software instruments, created using mentioned above methods, are shown. Vectorization precision and velocity values compared to known analogs are presented.

Methods for isolines detection, height marks, and isolines’ signatures recognition on raster topographic maps, that were scanned from paper medium, and their composition to vector and digital elevation models are described. Experimental investigation results, namely, precision and velocity values, of DEM construction in automatic and automated modes are presented.

This paper studies a vehicle speed intelligent warning system, designs a vehicle safe running and intelligent control system with dynamic recognition and automatic control functions and establishes the architecture of the intelligent control system. This system judges the safe state of a vehicle automatically by comparing its real-time running speed with safe driving speed limit and then gives the vehicle driver a clue by releasing the vehicle speed warning information and finally controls the running speed by vehicle control module.

Forests are essential for survival and sustenance of life. Their growth should be optimized so that greater benefits are derived from them. With such a large establishment and geographical base, the monitoring and decision making becomes very critical. The inherent delays hamper the decision process required at a particular time. The increasing area covered by forest plantations creates a demand for trustworthy mechanisms to ensure they are responsibly established and managed. However, most are focused exclusively or prevalently on natural or semi-natural forests, while only a few are specific to planted forests or plantations. The main aim is to assess whether and to what extent planted forests are properly considered within the existing sets of standards/guidelines and to identify areas for improvements, is based on a series of comparative analysis. This paper focus to carry out the full potential of convergence of GIS and Mobile Technology for plantation, with emphasis on technically viable infrastructure solution based on sustainability principles. Integration of GIS and Mobile is being proposed with an objective to enable a single window access to information and services being provided by various formations and to establish a collaborated environment.
