Knowledge system, which has been designed, will implement basic tasks with geodata: 1. classification of digital images, 2. georeferencing, 3. definition of basic parametres of the gravity field, 4. analysis of deformation. The first two tasks are concerned in preprocessing of primary image data, so that pictured objects will be correctly automaticaly classified and related to a certain place on the Earth (georeferenced). Main importance of the third task is the accurate hight localization of objects. The fourth task introduces the typical usage of geodata - positional prediction of deformed objects in time. Methods of solutions are based on verified theoretical knowledge of probability theory, geodesy, geophysics, mechanics of continuum, etc., which will be creatively inovated. Whole knowledge system will be implemented on the web server and will provide free and easily accessible computational tools for sophisticated work with geodata.
