*Lead photo: Early experiments in Vermont with the Public Lab's infrared camera tool.* **Vermont is part of the [Northeast region](http://publiclab.org/wiki/northeast).** Public Lab organizers Chris Fastie and Ned Horning are involved in multispectral imaging hardware, multispectral image processing, control and monitoring of airborne cameras, agricultural and vegetation mapping and imaging, and spectroscopy. . . PLOTS and TAC join forces in Vermont Public Laboratory and the Toxics Action Center are collaborating on a project to apply Public Lab tools to several Vermont projects being investigated by TAC. Details of these projects are outlined here. . Recent Events . . LEAFFEST 2014 September 12-14, 2014 [Vermont Fall meetup](http://publiclab.org/tag/leaffest2014) .
