Description

technical field

[0001] The present invention relates to the field of Internet Geographic Information Services (Internet GIS: Internet Geographic Information Services), in particular to the field of generation and display of electronic maps, specifically a method for generating and displaying electronic maps based on Flash technology on a computer. Background technique

[0002] The unprecedented development of the Internet has made electronic map search a widely developed function for users at all levels. Users can search, map and operate geographic information data directly through the browser. Users can easily find addresses and walking, bus or driving routes through the electronic map, which greatly facilitates users to find addresses and roads. Users no longer need to look up the location of a certain address or the way to go on a certain road on a huge paper map.

[0003] Among the current Internet electronic map functions, the user submits a map query request to the b...
