sample datasets for Ecosynth


It seems the data site of Ecosynth is down. We are trying to learn this tool to use it in our study of biomass calculations in our campus of IISc Bangalore.

It would be great if we can get access to sample dataset images so that we can understand the working of the tools as such. We shall be thankful for accessing the datasets. Kindly let us know.

Agisoft Photo detection and side overlap


I am a new Ecosynther. I am following your papers for designing  and improving last year's flight plans. AgiSoft.JPG here is a screen shot of photo list shown in Agisoft photo viewer window. These photos were taken from a lodgepole pine stand. Agisoft can't read most of the images, as only a few are ticked (according to my understanding). Please advise me how can I make these…

Ecosynth training flies through UAV and 3D modeling basics

An Ecosynth training was held at UMBC in December 2015 with participants from the GES graduate school and faculty of UMBC and UMCP. The training first organized a pre-flight checklist and reviewed flight safety measures including mention of current FAA regulations. In addition to the mechanics of lightweight UAV flight, participants developed and executed their own flight plan using Mission Planner software. Students…

Interest in using Ecosynth for remote sensing course

Hi all,

I teach at UMCP in the Department of Geographical Sciences' professional masters in GIS program. One class that I teach is an advanced remote sensing class focused on lidar. I would love to bring Ecosynth into my course, perhaps as a lab assignment. That way I can introduce my students to a low-cost alternative to lidar for generating point clouds.

I have yet to use Ecosynth myself, so I'm a bit of a beginner (my expertise is mostly in lidar remote sensing).

first point cloud

My first point cloud

Here is a point cloud we made with a Phantom 3 quadcopter and AgiSoft PhotoScan. We exported it in the Po-Tree format then put it on the web by editing an example from the free potree viewer(

RFID tags in the forest

I remember many times in our field plots at UMBC where we discussed the idea of planting RFID (Radio frequency identification) tags on our trees to improve future re-census and as a way to get around people stealing the tags (…

Replacing propeller adapters for 3DR X8

Hi everyone,

We broke (or stripped) a few of the propeller adapters on our 3DR X8. We're trying to replace them, and I ordered adapters from 3DR but apparently the ones they list online aren't the ones for the X8. I didn't realize that.

We have two copters so we could take adapters from one and put them on the other, except 3DR ships them with the adapters screwed in and glued with threadlocker. Solvents can undo this, but it seems like a solvent might mess with the…

Automatic image georeferencing

Dear friends,

I have been suggested to write this post to point your attention to a free software i'm being developing for automatic image (and 3d model!!!) georeferencing.

It is called AutoGR-Toolkit and it is based on image matching. It provides thousands of ground control points in seconds.  These points can then be used in ArcGIS or QGIS (for 2D matching) and also in Agisoft Photoscan, VSfm or sfm_georef (for 3D model georeferencing).

It also gives the possibility to…
