Grassroots Mapping is a series of participatory mapping projects involving communities in cartographic dispute. Seeking to invert the traditional power structure of cartography, the grassroots mappers used helium balloons and kites to loft their own “community satellites” made with inexpensive digital cameras.

Print maps from the PLOTS Archive and MapKnitter

May 10th, 2012 by Stewart Long

This was a bit lost in the hubbub over the Google announcement, but a few weeks ago we added a feature to order a print directly from MapKnitter and from the PLOTS map archive. Users can now click-through directly from their map details page. Public Laboratory map production is working towards a end-to-end open source solution:

  • Planning. Getting started with Public Lab map tools, collaborate, learn about safety first
  • Capture. Taking aerial images
  • Sorting. Selecting the best images locally or online with mapmill.org

PLOTS adoption of the CERN Open Hardware License

March 9th, 2012 by warren

Hello Public Labbers and Grassroots Mappers!

To date, the documentation and open science literature we've made as a community has been published under a Creative Commons ShareAlike license, allowing anyone to reuse, remix, adapt, improve, and redistribute our works. Today, the PLOTS Web working group would like to propose that we as a community adopt a separate license for our hardware designs, and after much consultation, we'd like to adopt the CERN Open Hardware License.

Aurora Tang’s Balloon Closing Method

February 5th, 2012 by mathew

This is Aurora Tang's method of sealing up her balloons. I think its the best I've seen. It was developed during a project to document Robert Smithson's Spiral Jetty with the Getty Institute. She has used it extensively for landscape photography.

Efficient Image Sorting with Finder & Preview (Mac)

I've made an instructional video on efficient image sorting with Preview and Finder, for quickly winnowing down big groups of images to small sets, ready for MapKnitter:

using a knot to trigger cameras

January 29th, 2012 by mathew

This is for use with the PET Bottle Rig

Instead of using a balled up piece of tape, a pebble, or some other thing to hold down my camera's shutter, I've gone to using a knot. This makes it easy to hold in place, and makes setting it easier. I prefer a rubber band, but tape also holds it down. tape may be more useful for bulging, non rectangular cameras.
