Problems solved by technology
[0003] However, the current mainstream GIS command and dispatch system on the market relies on relevant maps for personnel positioning and display. When using different map APIs for development, it is necessary to modify the corresponding logic and code. The code cannot be reused, making the development efficiency low.
And the walking and movement of people is presented in a flat 2D effect ( figure 1 ), motion in each direction has only one effect, which degrades the user experience

Embodiment Construction
[0048] Below in conjunction with accompanying drawing, the present invention will be further described:
[0049] A map can contain one or more layers, and each layer is made up of tiles at each level that cover the entire surface of the globe. For example, the map display including streets, schools, parks, etc. seen in most map commercial products is a layer. Use this technique to add data and corresponding functionality on top of each map layer.
[0050] Utilizing the technical characteristics of layers, the GIS-based map command and dispatch system is widely used in government, public security, armed police and other public utilities. This type of map command and dispatch system tracks and locates the staff in various event scenes, and realizes visual remote command and dispatch.
[0051] GIS-based map command and dispatch system, the related map functions realized include:
[0052] 1. Map dragging, with the function of dragging the map in any direction to view;

The invention relates to a character animation achieving method of a GIS command and dispatching system suitable for multiple maps. The character animation achieving method is characterized in that the maps correspond to Group containers in real time, namely the (0,0) positions of the Group containers always correspond to coordinates (minLong, maxLat) of the maps; a longitude and latitude coordinate of each person is converted to a screen coordinate so that the screen coordinates correspond to the coordinates in the Group containers in a one-to-one mode; invoking different pictures according the advancing directions the persons to form the animation effect. By adopting the method, the dependency on map development kits and API of achievement of map picture layer adding data and corresponding functions is overcome. The maps always correspond to the Group containers, so that the maps and picture layer data can be separated, and the dependency on the maps can be reduced. The character motion animation effect in the GIS command and dispatching system based on GIS is achieved.
Description
technical field [0001] The invention relates to a method for realizing character animation of a GIS command and dispatch system suitable for various maps. Background technique [0002] At present, the map command and dispatch system based on GIS is widely used in government, public security, armed police and other public utilities. This map command and dispatch system tracks and locates the staff at the scene of various incidents, and realizes visual remote command and dispatch. [0003] However, the current mainstream GIS command and dispatch system on the market relies on relevant maps for personnel positioning and display. When using different map APIs for development, it is necessary to modify the corresponding logic and code. The code cannot be reused, making the development efficiency low. . And the walking and movement of people is presented in a flat 2D effect ( figure 1 ), motion in each direction has only one effect, which degrades the user experience. Content...
