Description
Technical field
What the present invention relates to a kind of network electronic map dynamically goes out drawing system and method thereof, particularly relate to by commentaries on classics figure program and the map of each type of theme is merged and change into the figure shelves, again its map file is storEd in database, so as the user can directly read required electronic chart archives dynamically go out drawing system and method thereof.
Background technology
Because the development of every software engineering adds the quick emergence of surfing the Internet, Geographic Information System (GIS) software application category also went development from single one-of-a-kind system towards the network type GIS of many people diversification application system in recent years.But most network type GIS software price is too high, easily hundreds thousand of in addition have more up to 1,000,000 yuan, and the software of being bought also can be too old as to upgrade or upgrade because of the time, adds normal need and additionally buy other module, often allows domestic medium and small sized enterprises and individual user step back for it.
See also Fig. 1, Fig. 1 is the first embodiment configuration diagram that dynamically goes out drawing system of known network electronic chart.When the user will browse when selecting required Figure 152 electronically with Java Applet interface in a client browser 11, promptly need in Network Transmission unit 12 online after, ask a Website server 13 to transmit the figure layer data of Figure 152 electronically, Website server 13 then is connected to a map server 14, by the map file of Figure 152 electronically data on map server 14 accesses one database 15.But this known way user need download a plug-in program, and can be subject to the function that plug-in program has in the electronic chart functional development.This mode not only only can read the map datum of vector data, and has the misgivings on the data security.
See also Fig. 2, Fig. 2 is the second embodiment configuration diagram that dynamically goes out drawing system of known network electronic chart.When the user will browse when selecting required Figure 152 electronically with Java Applet interface at a client browser 11, by an extend markup language (XML) in Network Transmission unit 12 online after, ask a Website server 13 to transmit the figure layer data of Figure 152 electronically, Website server 13 then is connected to a map server 14, by map server 14 accesses one database 15, use a Spatial Data Engine (SDE) 151 to be connected to Figure 152 map file data electronically again.But this known way function is too complicated, and is adopting under the Java Applet front-end interface, when figure layer too much the time, the map graph that loads too complexity will cause system effectiveness to reduce rapidly.
