Silverlight 2.0 Map

Find a ready-made image on the map and draw the image above. The granularity is to the province. Theoretically, you can go to the district or county, but the workload is too large.
I discussed with my GIS friends that their GIS users usually require accuracy to the street, or even a manhole cover on the road. So what do I do? It is definitely not a GIS. If you only need to add data to the province, of course, it is currently a report presentation component that is still computed.

Through the first three figures, we can collect information similar to the following, such as the distribution of blog park users nationwide. Is the map messy? The map layer is much clearer.

The next two figures are suitable for the following statistics. For example, the Members who come to the Shaanxi blog Park Club to participate in the activity are friends from where. in addition, we can find some information that is difficult to find in the flat table. For example, we can say that the friends of this activity are not from the surrounding area, but from the surrounding area.

For the current problem, click to drill down. I divided several layers. The first layer is the map layer, the second is the vertex layer, the third is the text layer, and the fourth is the data layer, such as displaying the bar chart or associated line. the elements of Silverlight are very strange. It is impossible to define a range of irregular areas, all of which are rectangles, so it is very difficult for a map to capture the user's focus. the method I came up with later was to add a hotspot layer and use a rectangle box contained in the provincial figure to represent the hotspot area. However, it is confusing that any mouse event cannot be captured.

Some information is processed based on security considerations, and neither the Chinese data nor any real data is used.
