In fact, I have been to chinaquest a long time ago. At that time, I may still use plug-ins, so I have never been interested in him or not. Today, I happened to see that SVG was used.
After installing Adobe's SVG browser, you can see it. Not bad. You can't think of it as well.
View their CodeA full map of Shanghai is provided, but it is a pity that there will be no more. It seems to be a full graph. When you zoom in a range or drag it, it will generate an SVG cache to its server.
But what I don't know is that svgz is the SVG compression format. on the server side, he dynamically generates SVG from XML or databases and compresses it into svgz? And can svgz contain JS Code?
In fact, my goal is very simple. I just want to see the metadata in their SVG (including names and coordinates, but unfortunately these coordinates are not real coordinates ), let's take a look at how they display the map.
I don't know JavaScript or SVG, and I like my friends for more research.
The following two useful links are attached:
1. A simple WebGIS using SVG: http://songsgroup.cnblogs.com/archive/2005/09/26/243983.html. This eldest brother has published only one classic article Article, Dizzy. However, I still think it is worth studying.
2. Metamap: Memory. The menu on the left is made of SVG, the map is also made of SVG, and there is a tip box.
It seems that this GIS is booming. Plug-ins are small in Java. ProgramType, SVG type, raster type, and VML type.
