About me.

I'm a developer in LogicaCMG's Space business unit, often found dealing with Earth Observation or general "glue" like applications. The main things I've been working on for the last couple of years are the ground systems for the current series of Japanese Meteorological Satellites, and the detection of Impact Craters in remote sensing imagery.

Or "producing" and "looking at" pretty pictures, respectively.

I do other stuff, but I've tried to concentrate on work which has obvious web-accessible external consequences here!

Impact Craters

There's a huge amount of information on Impact Craters on the web. Some of which is dross, and much of which isn't classified in a particularly useful manner. Invariably the same ten lines of information are repeated, and the same small snapshots of much larger image scenes are reproduced.

Which is a shame, particularly since the sheer quantities of "free" satellite imagery now available means that theoretically some "nice" pictures could be stored somewhere.

Regardless, the following links are a bit more interesting (and/or cover my work on the subject - which at least means any errors are mine...):

Earth Impact Database
List of terrestrial impact craters, maintained by the University of New Brunswick - in particular the essay Introduction to Impact Cratering on Earth provides an introduction.
LPSC Slide Set
A set of slides showing a number of terrestrial impact craters. Unlike many of the pages on the subject you can find on the web, this set of slides makes a point of including contextual information. It's a bit out of date.
Brent crater
Website devoted to one man, his aeroplane and his various flights over Canada's impact craters. This particular page contains an interesting geological cross-section of the Brent crater, along with a short description of a walk through the forest that now surrounds the structure. This gives an idea of some of the difficulties involved in performing ground truth observations!
An article on Data Mining
Or, "why should users not interested in impact cratering be interested in the general techniques..."
ICDY project page.
Project page for the ICDY project, in which I've been involved.
Presentation on ICDY

LogicaCMG provide the Image Data Acquisition thingyibob (the precise acronym varies by project!) for the Japanese MTSAT-1R / 2 series of satellites.

Live imagery can be found on the web at JMA's MTSAT Website. At some point in the near future it will also be distributed as part of the Foreign Satellite Data transmitted by Eumetsat across Europe. This is a subsampled version of the original data captured at 1km nadir / 3 km nadir resolution respectively. The full resolution imagery is transmitted using the HRIT data specification.

There's an opportunity here for me to post a whole load of links to weather satellite calibration, image format and reprojection algorithms. But they're all at work, so I'll have to restrain myself :)


We provide a colour composite of Europe for the MIDAS system - here - based on MSG-2 imagery. HRIT format satellite imagery isn't well-adapted to GIS standards: but with a bit of thought it's possible to include live products in a GIS system such as this one...
