Management And Visualization Of GFIS

With the progress of method of gravitation measurement and optimization of data processing method, it is more and more convenient and quick to get gravitation data. In order to effectively satisfy the newer and higher requests which are brought forward by many information application departments of the of the gravitational field such as missile, spaceflight, surveying and mapping, physical geography, geologic mineral resources , etc , to continually provide them with all kinds of the gravitational field productions through complex processing; In order to better storage and manage a large number of all kinds of the global gravitational field information and they are increasing continually, to effectively use these information for long ; In order to change the yesterday laggard situation of the expression ways of gravitational information, to help people to realize the intrinsic relations of gravitational data clearly and visually; In order to realize modernization and automatization of data process and management, to enhance work efficiency and to adapt the request of rapid response. The management and visual of the gravitational field information system software can satisfy the above-mentioned application requests.This paper introduces the development method, total functional structure, data storage and process, attribute data search, segment image walkthrough, the function of data segmentation of the system. The software is designed with the language of C++ on the Windows 2000 operating system. The production of this paper has great reference value for future management and visualization of gravitational field data. The color quantification and management, section data organization , section memory management and the overlap of raster and vector data in the software design have some values to use for reference for other correlative system developers.
