GXSM

The Gnome X Scanning Microscopy project is a powerful graphical interface for any kind of 2D and 3D (multilayered 2D mode) data acquisition methods, especially designed for SPM and SPA-LEED, which are used in surface science. It includes methods for 2D data (of various types: byte, short, long, double) visualization and manipulation. It can be used for STM, AFM, SNOM, SARLS, SPA-LEED and CCD (very special), but is by far not limited to those! Especially in standalone mode it can perform many SPM typical image manipulations and analysis tasks.
