Aerial photomaps can be very useful to EWB chapters for community,

site and project planning; agricultural/ ecological planning and

evaluation

•This poster shows how to make simple inexpensive aerial photomaps.

This approach was presented and demonstrated at the EWB West

Coast Regional Workshop in October 2010

•What’s needed: equipment, software, supplies, materials

•digital camera with ability to take photos automatically

•GPS unit with tracking and logging capability (where needed)

•A package to house the camera and GPS unit

•Balloon or kite with enough lift capability to carry the camera, GPS

unit, housing and sufficient tether line to reach height of interest for the

photographs (or R/C aircraft)

•A safe approach to use the process in the field

•Capability to process the data and present the results

•An approach to discuss and use the results

•This poster points to web resources and an on-line Illustrated Guide

•Examples are shown from community of users

•We’ll demonstrate – let’s go fly!

•Stop by after – see results, Q&A

A complete grassroots mapping kit by Jeff

Warren

In April 2010, Deepwater Horizon rig

exploded and sank in the Gulf of

Mexico - volunteer aerial mapping

teams documented the spill (image by

LA Bucket Brigade/Gonzo Earth)

LA Bucket Brigade volunteers map with

balloons and kites

Gulf oil spill mapping approach•Participants visit an affected area, fill a balloon or prepare a kite

depending on wind conditions, and send the camera in its

homemade protective enclosure up to 2000 feet in the air

•By walking along the beach or moving in a boat, several kilometers

of coastline may be imaged in just a few hours

•Between May 7 and July 22, 2010, dozens of participants made 36

trips to gather mapping data, averaging almost one trip every other

day

•Only one trip failed to return with imagery, 56% of the trips

returned with "excellent" or "usable" data, and over 11,000 images

were taken

•The maps use orthorectified photographs of key affected sites

processed into GeoTIFFs and tiled map services (TMS) - the public

domain photographs, taken from balloons or kites, are among the

highest resolution imagery available of the spill

•Two different manual processing methods have accounted for the

bulk of the mapping for Grassroots Mapping

grassrootsmapping.org to date:

•Gonzo Earth Image Processing is a workflow of different

commercial off-the-shelf (COTS) and open-source GIS and digital

image software packages, which has been used to generate dozens

of maps from balloons, kites, remote controlled and manned

aircraft

•The Cartagen Knitter software consists of a free web-based

interface for users to upload and rectify images from a web browser

•Both export finished maps in standard formats including GeoTIFF

and TMS, to be viewed in common GIS tools and integration into

existing workflows
