Stitching Google Map Images to Create a Large Map

The size of the images that can be printed/ captured from Google Map is limited to the dimensions of the browser window. In my previous post “How to capture, print a large Google map – larger than the screen” I explained to you how you can save large images. However, the size of the images that can be captured using Google Map Customizer is limited to the hardware performance and the internet speed.

If the size of the image that can be captured with Google Map Customizer is not large enough, you can capture it as multiple images and stitch them later. But, stitching them manually is not so easy. In that case, you can use Microsoft Image Composite Editor (ICE) to stitch the Google map images.

Image Composite Editor (ICE)

Image Composite Editor (ICE) is an advanced panoramic image stitcher created by the Microsoft Research Computational Photography Group. Given a set of overlapping photographs of a scene shot from a single camera location, the app creates high-resolution panoramas that seamlessly combine original images.

Stitching Google Map Images with Image Composite Editor (ICE)

To stitch the images with ICE you need to capture all the images with the same zooming level. And also your images must have overlapping sections with the image you are intended to join.

You can see in the following video tutorial how easily you can join the Google Map images with ICE. In this example, I am stitching four 10000×6000 pixels images captured with Google Map Customizer.

First, you need to import the images ICE. After you upload the images, leave the default settings and click “Next”. In the next step, you can see that ICE has correctly positioned your images and now you are ready to stitch them. Leave the default settings and click Next. Now your images have joined and click Auto Complete to optimize your image. ICE will crop the image to get the maximum area. Then click Next. In the next step, you can adjust the quality settings. Then click Export to disk… to export your image.
