Research of Making Color Scheme of MapGIS Meteorological Thematic Products

As an important spatial information technology,GIS has played more and more essential roles in the construction of meteorological information system.Aiming at the map style of different meteorological thematic maps,this paper edited the GIS files of the point,line,and polygon of legend,title,and map frame.The style files(.XML) are saved for publishing on the WEB,and can generate color scheme file(.XML).Using the SDK and components library of MapGIS platform,depending on the easy construction idea of data centre,the components in the function library of data centre are integrated to a large function model according to the requirements and types,and then the function models are integrated to the main framework of the system.The overall technical framework of background scheme management system is also explained.It realized the visualization management,color scheme management,workspace edition,legend edition,title diagram edition,and other series of desktop GIS applications for geospatial information data.
