Use this tool to compare images and see how time changes all

March 20, 2017

Juxtapose was developed by the Knight Lab to allow users to compare two images.

Juxtapose is a #dataviz tool developed by students at the Knight Lab. It allows you to compare to visual images (.jpg, .png or .gif) in order to see transformations or comparison over time.

As obvious examples are: the evolution of a territory over the years, environmental impacts, the growth of cities or urban development, among others.

 

This tool is free, responsive easy to use and works on both Android and iOS systems.

 

We used the tool in Datasketch in order to compare two different cities that have the same name. We wanted to spot the differences visually. Thus, we used Juxtapose. This is one of the results:
