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.

Help requested with mapknitter- Balloon mapping of Metal processing plant in Providence, RI

May 13th, 2013 by Lynnrw

We're a neighborhood group in East Providence, RI with houses adjacent to a large construction waste grinding business. Toxic dust was filtering into our homes and yards from the plant. Many in the neighborhood suffer from respiratory and other health problems thought to be associated with the dust.

Balloon Mapping From the Ground Up: Public Lab’s Field Techniques

January 2nd, 2013 by Stewart Long

cross-posted from PBS's IdeaLab

Public Lab's balloon- and kite-based mapping approach is a new way to take aerial images from the ground. However, there are some considerations and things that can be learned from a few map stories.

Each map project has distinct characteristics in its time, place, and local atmospheric conditions. Here are several examples of how those factors make each balloon and kite map unique.

map of Bayou Bienvenue CIAP restoration ("B" of Green Slice area)

October 7th, 2012 by eustatic

TECHNICAL NOTE AND QUESTION

We're going to have to repeat this one. The camera shut down prematurely.

I attribute the failure to the use of duct tape on the camera trigger-- any thoughts on this are appreciated. From looking at the photo sequence, the camera gave out after a wind gust. Still, some interesting shots were taken.

And, in the future, i will be using the Common Ground kayaks, so repeating this day will be easier the second time.

Lee, NH PLOTS/FarmHack Meetup

May 29th, 2012 by cfastie

We had a successful day last week balloon mapping an agricultural experiment study in Lee, New Hampshire. Dorn Cox of GreenStart hosted the day at the site of a no-till trial where hairy vetch had been seeded the previous September into established hay field turf. Thirteen different experimental treatments with four replicates each are designed to reveal the best management practices for conserving fuel, enhancing soil carbon, and reducing weeds while switching from grass-based to legume-based cover.

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
