Error, Certainty, and Sharing Results

I love American Geophysical Union’s  weekly newspaper, “EOS”. It’s a great weekly summary of what’s going on in the earth sciences. I make it a point to stay current on it, even at least skimming an item if it’s not … Continue reading

The Spherical Cow: Models and Applications in Geoscience

I had a great physics teacher in high school, Mr. Dechant. I still use what I learned there. Some vector componentized wind data from NOAA I’m currently wrestling with comes to mind. He probably should have gotten an award just … Continue reading

Seeing More Than Just The Surface

When remote sensing first got going, it was really expensive. If you were going to go to all the trouble and expense of building a costly, finicky, short-lived instrument and put it in orbit, you really needed to be finding … Continue reading

Creating a Geospatial Toolbox Masterpiece

Last week I hosted a webinar on how to extend and customize ENVI using IDL (watch a recording of it here). Short summary: create and use your own software tools and algorithms for earth science and remote sensing. This was … Continue reading

NOVA: The Earth From Space

No matter what your job is, it’s usually very difficult to explain what you do to someone who doesn’t work in your field. And oddly enough, the more you like what you do, the harder it gets to explain your … Continue reading

Blank Spaces

If a discovery unshared is a discovery lost, then good science must include good communication. In the earth sciences, that means you better have really good geospatial data including maps, imagery, and more. The Big Picture maps for that kind … Continue reading

From Imagery to Data to Science

I love science. I love learning it, doing it, teaching it, and sharing it. But here’s the thing with science: it goes nowhere fast without data. That’s actually one of the things I like best about science, its course isn’t … Continue reading
