I'm planning to make an application like google maps only to a city in my country. I want to use XNA WP7, but I get a lot of problems here

1. Is it possible that I detect a road just by detecting colors on the map that I created? or I must draw the line functions in XNA? and declare each point of the road?
2. second, whether I can control the image in XNA? how?
3. How do I get the position coordinate / pixel in the image rather than on the screen?

please give me an opinion, or give me a tutorial that relates to my project ..

Do you want to use Google Maps in particular, or can you use Bing Maps? If you can use Bing Maps, then there's a built in control that handles a lot of the hard work for you. You can download sample code on how to use the Bing Map control from here.
