Behind the paper: Spatial variability of the atmosphere over southern England, and its effects on scene-based atmospheric corrections

I’ve just had my second journal paper published, and so I thought I’d start a series on my blog where I explain some of the background behind my publications, explain the implications/applications that my work has, and also provide a brief layman’s summary for non-experts who may be interested in my work. Hopefully this will […]

What’s new in Py6S

The last few months have seen a flurry of activity in Py6S – probably caused by procrastinating from working on my PhD thesis! Anyway, I thought it was about time that I summarised the various updates and new features which have been released, and gave a few more details on how to use them. These […]

How to: Fix weird ENVI startup file issues

This post is more a note to myself than anything else – but it might prove useful for someone sometime. In the dim and distant mists of time, I set up a startup file for ENVI which automatically loaded a specific image every time you opened ENVI. I have no idea why I did that […]

Simple parameter files for Python class-based algorithms

As part of my PhD I’ve developed a number of algorithms which are implemented as a class in Python code. An example would be something like this: class Algorithm: def __init__(self, input_filename, output_basename, thresh, n_iter=10): self.input_filename = input_filename self.output_basename = output_basename self.thresh = thresh self.n_iter = n_iter def run(self): self.preprocess() self.do_iterations() self.postprocess() def preprocess(self): # […]

How to: Find out what modules a Python script requires

I do a lot of my academic programming in Python, and – even though I often write about the importance of reproducible research – I don’t always document my code very well. This sometimes leads to problems where I have some code running fine, but I don’t know which modules it requires. These could be […]

Software choices in remote sensing

I recently read the article Don’t be a technical masochist on John D. Cook’s blog, and it struck a chord with me about the way that I see people choosing software and programming tools in my field. John states “Sometimes tech choices are that easy: if something is too hard, stop doing it. A great […]
