<div>Hi Henning, <br>
I think that the memory for normal Files is managed in a different, probably better way by the JRE.<br>

I got an OutOfMemory exception (see below) while reading zipped 1" SRTM<br>
files in Scandinavia. Unzipped it's all fine.<br>

Btw. it would be nice to move the 'DEM file calculation for ... took 265<br>
ms'-messages from stdout to logging Information.<br>
