I've been trying to do something very similar with a hex that I have available, but I've been having terrible luck with our cameras. I've tried a PowerShot A3400IS and PowerShot SX200IS, but both have struggled to take…"

Gareth Rens commented on Mark Willis's blog post Aerial Mapping with multicopter"@Mark, Thanks buddy :) Im new to the whole photogrammetry thing. Question, im using photomodeler scanner. Are GCP neccesary and what exactly are they? Are they virtual or are they like physical calibration sheets that you put on the ground? Thanks!"
Mark Willis commented on Mark Willis's blog post Aerial Mapping with multicopter"Gareth, A Nikon CoolPix should work fine for photogrammetry. Most of my cameras have lower resolution than that.
-Mark"
Gareth Rens commented on Mark Willis's blog post Aerial Mapping with multicopter"Will a 16mp Nikon coolpix be sufficient for photogrammetry? Im going to be doing volume measurements of compost stacks."
MC replied to Mark Willis's discussion Cardboard Quad"I was interested in using NTM but there are a few negative reviews on HK, not sure what they are worth (the reviews), but they look well built. Have you had any problems with them?
Anyway, fantastic work!
Awesome laboratory."

Creating Digital Elevation Models from Low Altitude Photographs
Posted on December 30, 2010 at 10:11am 12 Comments 0 Likes
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…
Continue Introducing Palentier: An Open Source Aerial Mapping Application
Posted on September 28, 2010 at 11:30am 17 Comments 0 Likes
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…

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…
