Terrapattern

A machine-learning based visual search tool for maps

 

Overview

Terrapattern is a prototype for helping people quickly scan extremely large geographical areas for specific visual features. It seeks to help people identify, characterize and track indicators which have not been detected or measured previously, and which have sociological, humanitarian, scientific, or cultural significance. Instead of searching for a location based on a text query, with Terrapattern one can click on a place in a map to find other similar-looking places. 

Terrapattern Tool

Go to the Terrapattern website to try the service. The about and FAQ pages contain more information about our technical process, mainly covering data gathering and the deep convolutional neural net (CNN) we used to assist with image recognition. 

This version of the system is meant to be a proof of concept - a prototype suggesting new possibilities for using maps and searching through visual information. A more robust version 2 is currently in development.  
 

 

Tools: Ruby, Processing, Javascript, HTML, CSS, Sketch, geo libraries

Year: 2016

Team: Golan Levin, David Newbury, Kyle McDonald, Aman Tiwari, Manzil Zaheer

Role: Project ideation, dataset creation for CNN, prototype web design and development

Examples

Terrapattern is ideal for discovering, locating and labeling typologies that aren't customarily indicated on maps. These might include ephemeral or temporally-contingent features (such as vehicles or construction sites), or the sorts of banal infrastructure (like fracking wells or smokestacks) that only appear on specialist blueprints, if they appear at all. It is important to point out that the Terrapattern system was not trained on any of the categories shown below, but instead recognizes them because of their common visual features.

Here, for example, are golf course sand traps identified in the Pittsburgh metro region:
