Graphs in JMP 9 can use the new Background Map feature. If you have an X co-ordinate and a Y co-ordinate on a graph (or your table has place names that reference co-ordinates in another table), you can use various map servers to provide a background map for your graph.
JMP 9 comes with two built in world maps, and the NASA maps seem to be working now. NASA maps are good enough for rough city level data. The built-in maps are not very detailed. For example, you can't zoom down to city level, at least in Canada.
So, I decided to use one of the Canadian federal government's free Web Map Service servers to get a detailed map of Vancouver.
I'll throw up a video soon, but for now, here are the basic steps to use a custom WMS map of Vancouver in JMP 9:
- Open a data table that has co-ordinate information in it (ie longitudes and latitudes).
- Open Graph Builder and drag your longitude column to the bottom of the graph, and your latitude column to the left of the graph.
- Right click your graph, and choose Graph - Background Map...
- Select Web Map Service, and set the URL to this:
and set the Layer field to feature_names,hydrography,vegetation
[You can see the full version of the map here]
The above is Natural Resource Canada's WMS map server. It only works for Canadian co-ordinates. Other WMS servers are available. And now you have a nice detailed map of Vancouver.
JMP 9 would be better if it saved your custom WMS URLs, showed error responses from the WMS server, and showed a selectable list of all the available layers. There is now a JMP add-in called "WMS Explorer" that does this.
I'll post more soon about integrating Vancouver data with maps.
