I've never used Google Map data in MATLAB, but you might want to take a look at this File Exchange link:

I do know that you can access map data from the Web Map Service directly through MATLAB. This is an API for geographic data from multiple sources. You can choose one you like from the documentation page here:

This is an example of how to access and use some cloud data from a NASA server. You may be able to modify this code for your needs:

Once you have map data in MATLAB, you can create a contour plot with the 'contourm' or 'contourfm' functions. Here is the documentation for these functions:

Good luck!
