Version 1.13 of Snuffler released

It's time for a new version of Snuffler, and this version is all about importing stuff. There are two new files imports for getting data into Snuffler.

The first is for importing TerraSurveyor (was ArchaeoSurveyor) grids and composites. TerraSurveyor is a (very good) commercial equivalent to Snuffler. Someone sent me some data in that format, so I took the opportunity to write an import for it.

The second is Surfer ASCII grid files, not to be confused with the ASCII Grid files that ESRI produces. Surfer is software for displaying 3D geographical data. It wasn't data from that software specifically that I was trying to import though. ReflexW, the GPR software I use, has an export function for time-slices in Surfer ASCII grid format and I wanted to play around with slice data in Snuffler. Here is a time slice from the site I covered in my last post display in Snuffler.

You can download the new version at the usual place.

Geophysics on WWI Camp in Eastbourne

World War I is very much in the news at the moment, due to the centenary, so here is some WWI geophysics to entertain you. The site is the extreme south-east corner of Summerdown Convalescent Camp in Eastbourne, which is very near where I live. I got to use my new GPR system, which is always good, and it showed up the archaeology quite nicely. In the area surveyed, there are ablution and barrack blocks. The former have fairly solid foundation structures while the latter were built on a series of concrete piles. See if you can spot the in the image below. I would compare this to what was excavated... but no-one told me when the excavation happened. You can see the full report here and watch a movie of the time-slices here.
