  2. Mapping biodiversity in local parks with grassroots bioblitzes We take

    an average of a thousand geotagged iNat observations and confirm at least a couple hundred species at each event

  8. Mt. Diablo Morgan Fire For our first effort, we're documenting

    habitat change in the aftermath of the Morgan Fire on Mount Diablo, which burned 3,100 acres in September 2013. ! We're collaborating with Mount Diablo State Park and the Wildlife Society, Western Section.
  9. How It Works

  10. Installation Four sign/bracket locations on hiking trail overlooks provide both

    close-up and distant views of the burn area.

  13. Why improve & automate? Requests to help monitor other eco-systems

    • Aftermath of the Yosemite Rim Fire (second largest in CA history) • Aftermath of South Bay proscribed fires • We expect many similar inquiries in the future ! Other applications we envision • Public events like Maker Faire (where we will have Change Bracket signs) • Construction and pollution sites • Gardens, greenhouses, and farms
  14. What can we build on? 1. Ken-ichi's js code and

    relevant html is in the public Github repo here: ! https://github.com/nerdsfornature/nerdsfornature.github.com/tree/master/ monitor-change ! ! 2. The script that Ken-ichi has been using to write a nightly file of recent tag usage: ! https://gist.github.com/kueda/937d12c280dc5ae8d1af
  15. Slideshow Upgrades ! • Update the existing website and sync

    script to read and write data to a Google Spreadsheet, with column to allow manual exclusion of bogus (hi mom!) images from the project. ! • Make a totally free, bugless, self-sustaining web app on Google App Engine that lets people enter a set of tags and then it will regularly archive image URLs to a spreadsheet, along with a page equivalent to our existing site to show a slideshow. We doubt such an app would ever be popular enough to surpass Google's free quota, and if it does, business plan!
  16. True Timelapse Upgrades • Document a manual method or develop

    an automated way to generate time-lapse movies using photostitching software like Hugin. ! • Make a timelapse programmatically with Python Imaging Library (PIL or Pillow) or whatever image processing lib you like. ! • Make a timelapse programmatically as above and make it automatically choose control points, adjust for exposure, and account for elapsed time variations. ! • Use openCV to find control points?
  17. Project Wizard Upgrade For bonus points! Develop a way to

    make this an easily replicable sort of campaign by filling out forms or something to generate sign images and twitter scripts and set up a web server and blog/slideshow/movie and so on. ! Currently the sign image is an Adobe Illustrator file/template.
