Geological Image Analysis Software - GIAS v1.1; December 2009

Help
The GIAS GUI can be described in three parts - the upper panel (in green) which allows files to be loaded in, controls the input paramters and sets the unit size and the name of theoutput files. The Image Analysis panel graphically outputs the details of the given image, including the area, orientation, perimeter and number of objects analysed. The Nearest Neighbor panel computes and graphs the statistical distribution of the distances between objects, allowing the user to test the distribution for randomness or four other statistical models. Please click on the links below to access help on a particular Panel.
