Land Lines uses gestures to find matching Google Earth satellite images, turning drawn lines into visual compositions.
About Land Lines
Land Lines is an experiment from Chrome Experiments that lets users explore Google Earth satellite imagery through drawing gestures. In Draw mode, a user draws a line and the site finds satellite images that match it. In Drag mode, the site builds an continuous line of connected rivers, highways, and coastlines.
The experiment combines machine learning, optimized algorithms, and graphics card power to run in a phone or desktop web browser without backend servers. To prepare the image set, the team used OpenCV Structured Forests and ImageJ Ridge Detection to find dominant lines in more than 50,000 images, narrowing them to a few thousand. The source states that all images are hosted on Google Cloud Storage. The homepage also shows a message if the browser does not support canvas.
