Hi,
As a supplemental aspect of my current research into land cover change within the UK I am trying to use Landsat 5 data in order to assess the validity of differing approaches. I have access to neither ERDAS nor ENVI and have been using R to manipulate the data. However, I am still getting significant categorisation errors. Does anyone know of a good free alternative to said software or a good way of processing data in R or Python?
John Rahilly Do you have access to ArcGIS? If so, you can run arcpy based supervised/unsupervised algorithms on the Landsat 5 data to assess Land cover change.
I have QGIS [which I have also tried with the SCP Plugin on the data], but don't currently have access to ArcGIS.
QGIS works too! If you perhaps look into PyQGIS documentation, you should be able to fairly quickly run an unsupervised/supervised algorithms. PyQGIS is not as extensive as ArcPy, but it gets the job done.
