"I agree.  Every time I need to find the logs, I have to load this post to be reminded where to look.  I hope they'll consider moving the logs to Tower/logs or something similar."

Flying the Iris+ in strong winds

https://youtu.be/fFTSLd96c4IThis video shows the sort of chaotic winds the #3Drobotics Iris+ can handle.  I was able to collect data in 18+ mph without any issue over several days.  Wind gusts where much higher and the Iris+ did fine.See More

Creating Digital Elevation Models from Low Altitude Photographs

Posted on December 30, 2010 at 10:11am 12 Comments

A free tutorial on creating Digital Elevation Models (DEMs) from Photosynth point clouds is now available online.  The tutorial focus on using mostly free and Open Source software to create detailed georeferenced 3D models from low altitude aerial photographs that have been processed in Structure from Motion (SfM) software like that…

Introducing Palentier: An Open Source Aerial Mapping Application

Posted on September 28, 2010 at 11:30am 19 Comments

http://www.palentier.com

Palentier processes aerial photographs collected from a camera aboard a MikroKopter, or similar Unmanned Aerial System (UAS) then scales, orients and projects the images to real world mapping systems. It does this by analyzing the telemetry data from the UAS and merging it with the aerial photographs. The resulting data is then superimposed for viewing in Google…

Aerial Mapping with multicopter

Posted on June 8, 2010 at 10:00am 29 Comments

Hello all, I've been toying around with the MikroKopter Hexakopter as a tool for aerial mapping and photogrammetry. After a few weeks of learning the ins and outs of the system, I finally had some time on the weekend to test the system for mapping.



In short, we placed Ground Control Points (GCPs) around a man-made ponding area at roughly ten meter intervals (~40 x 30 m in total…

Hi Mark

Take a look at the following sites:

www.aerogeonautics.com
www.aerialinsight.com

Both are using data logged during the flight to improve the ability to accurately geo-reference and model the imagery acquired during small uav flights.
