Have you ever wanted to create a high res google street map like 5000 by 5000 with a customised colors without going through the hassle of merging multiple screen capture in photoshop the start selecting and picking customising colors. I had a project where I needed such thing and after a long search I found sth called Google Map Customizer made by Aaron Cheng. The code is based on Google Maps and Google Maps Colorizr.
Google Map Customizer lets you customize the colors on a Google Map. You can select customizations for any map aspects you want, such as the natural landscape. For this aspect you can enter the HEX code of the color you want it to be filled with.
Google Map Customizer lets you get large, high resolution satellite maps, typical Google maps and custom maps made by Google Map Engine. You can simply zoom into the level of detail you want and setup the window dimensions big enough to capture the site area you need. Then all you need to do is to grab the screen shot.
So in short just go to this page and start capturing:
