I've got a question for all you geologists out there (or whoever's left after my little blog break)...
if you have to create contours of some sort (bedrock elevations, water table, contaminant plumes), do you use software, or do you hand draw them?
I always contoured by hand, using a combination of triangulation and that elusive "professional judgement". Wherever I worked, we were too cheap to have any real contouring software, so I really didn't have much of a choice. I didn't even use simple software like surfer until I was in grad school.
At the same time, I've seen a number of astonishingly bad contours drawn by software. Here's a hint: in the real world, you tend not to have little divots and hills around all of your data points.
In the ideal world, I'd have some sort of software that would do a really basic set of contours, but that I could tweak by hand, using some sort of tablet and pen device. And the software (and peripherals would be not only cheap, but somewhat rugged.
Oh, well - a girl can dream, anyway.
