I would like to convert an image from google maps

enter image description here

into a black and white edition, without gray scale, something that will look like that

enter image description here

How can this be achieved with Adobe Photoshop CS5?

    Have you tried simply drawing it?

  • Try to play around with image contrast, gradient map etc.. I do concur with Scott that redrawing the map will probably yield a better-looking result, though.

  • @Scott: Thank you very much for your comment. Unfortunately, I have to include the maps from google, therefore drawing them cannot be applied here. Even if it could, I don't think I could make it look exact;y like google.

  • @Bakabaka: Thank's for your comment. I tried to play a bit with B&W filter, contrast but the outcome is always something in gray scale...

  • @Thanos: after you've made a greyscale, try using Image > Adjustments > Threshold for a true B&W effect.

The closest you could probably get without drawing it is to use the filter > stylize > find edges (adjusting the contrast first might work better). Once that is applied, use the threshold adjustment to make it black and white.

Here is a quick example of the result: enter image description here

Another way is to use the filter gallery > stylize > glowing edges. This gives you a smoother line that you can adjust with sliders. Once you've adjusted it, use a threshold adjustment layer (adjust the slider), then invert it with the invert adjustment layer.

Here is what that looks like: enter image description here
