I am teaching an ad hoc class in remote sensing, where students are bringing their own laptops
I wanted to go over how to perform a supervised classification in the open source software I had chosen - gvsig, but even the simplest of tasks seem to fail.
I loaded in a Landsat scene, subsetted it to about 10% of the original area, created an ROI of a single small region of about 10 pixels - and tried to perform a supervised classification on it. It sat on creating spectral signatures for about 10 minutes, and then gave me an error along the lines of the array out of bounds or something similar.
Does anyone know what I might be doing wrong, or alternatively have another suggestion for open source software that can do supervised classifications that will work on both PC AND Mac?
QGIS will with the SCP plug-in, but the plugin appears to be for PC only.
