Solve the difficulty and meaning of above-mentioned technical problem:
With the surge of social information and vector landform, digital elevation model, orthography, ground mulching and soil benefit
More showing day for the importance of basic framework of the equal geographical spatial datas as all kinds of spatial mode information systems is used, to spatial data
Quality and quantity have higher requirement.The GIS with powerful spatial data analysis ability is made full use of, while to multiple
Steric factor is analyzed, and to multiple-factor spatial data superposition processing, creates new information；When simultaneously to coming from multiple and different
Between data analyzed, obtain dynamic-change information；It is carried out therewith by the digital elevation model (DEM) that GIS is set up three-dimensional
Stereoscopic analysis, and the digital achievement that further derives the gradient, slope aspect figure etc.At the same time, and by GIS towards web development,
Carry out open GIS research, the research of GIS functional unit and the GIS research based on WWW；GIS-Geographic Information System skill is utilized simultaneously
Art and remote sensing technology and global positioning system form resource environment Dynamic Monitoring System, are allowed to be able to grind from coming from new visual angle
Study carefully the economy and resource situation on periphery.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of controls of the database of resource environment dynamic monitoring is
System and method.
The invention is realized in this way a kind of database control system of resource environment dynamic monitoring, the resource environment
The database control system of dynamic monitoring includes: attribute data form module, graphic image data library module, management list mould
Block.
