After data message, it is static that host computer grid thread then utilizes the GIS platform in electronic equipment to be drawn according to static data information
Map vector.
After first time draws static map vector, host computer grid thread except using GIS platform to rendered
Static map vector carry out outside maintenance and management, obtain in the new geodata information loading according further to prefixed time interval
New static data information, and new static data information is compared with the static data information that obtains for the first time, if
Do not change, then do not drawn；If changing, such as：Because extension needs, parking lot is moved by original location A
Move to B location, at this moment, host computer grid thread will be according to new static data information, i.e. the first static data in the application
Information, is drawn, and obtains the first static map vector.
In the embodiment of the present application, after carrying out first time static vector drawing, only occur in static data information
During change, just being drawn again, thus avoiding the distributed raster data containing static data is updated, being carried with reaching
The high technique effect drawing efficiency.
