For a few years now, Public Lab’s open hardware community has been developing not only DIY tools for taking multispectral photos, but also software tools to process and analyze these photos—the Infragram project, and more recently the Image Sequencer project. These have enabled many people to take multispectral (near infrared/visible) imagery and do NDVI plant health analysis at home, on a...

Across the Public Lab community, people are making their own maps using aerial photos (by balloon mapping, kite mapping, and the like) with the MapKnitter website - which helps people "stitch" or "knit" images into a combined map, using an existing satellite map base layer as a reference. (this post was cross-posted on the Public Lab blog) The core...

Since 2011, Public Lab community members around the world have been building and using modified consumer cameras to take multispectral photographs, enabling thousands of people around the world to explore the world around them using vegetation analysis tools such as #NDVI. As illustrated above, comparing infrared and visible light can offer clues to plant health, and DIY...
