How to unpack PanMap layer-files from zip-archives on Macintosh
Layer files with geographical information, to be used with PanMap, can be downloaded from http://www.pangaea.de/Software/PanMap as zip-archives. Macintosh users must press and hold the mouse-button. Choose "Save this Link as...".
PanMap should already be installed on your Macintosh; a zip-archive with PanMap-layers was also downloaded.
The layer-files will show the PanMap layer icon and can now be used with PanMap's LayerManager.
