From the image in the article it looks to me like the researchers are using commercial software from Agisoft, called PhotoScan[0]. For free (but not enitrely OS) you can look at VisualSfM[1], which is a GUI which pulls together a variety of

Can you share any more on this project? We're currently working on a project for an environment agency to determine viability / produce a proof of concept for monitoring methane levels over landfills using UAVs.

I've never understood why USA PhD students appear to be paid so badly. My stipend was 36k USD (tax free, so compared favourably with the salaries of my friends who went into industry). I worked pretty much 9-5 with the occasional lat

Hmm yes perhaps, I tend to think of a dial as part of a measurement device. So a volt/ammeter has a dial, a clock has a dial etc. I suppose I could see myself calling the temperature setting of a cooker the "Temperature dial", but not the

Plenty of British English speakers would use the word "knob", for example I have no idea what I would call the knobs on the cooker other than knobs. Or the knobs on amplifiers, or door knobs - well I suppose door handle works but door knobs
