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
