Kabazah Posted February 17, 2015 Report Share Posted February 17, 2015 Hi all I have been trying to perform PCA on 2001, 2007, 2013 and 2014 Landsat imagery and keep on getting an error "source base Data is NULL". I am using ERDAS 8.4 Quote Link to comment Share on other sites More sharing options...

agraham1 Posted March 14, 2016 Report Share Posted March 14, 2016 A little bit late for a reply- but the reason you are likely getting that specific error message is because you didn't calculate the statistics. Set the skip factors to 1 and recalculate the stats then you should be able to run the PCA. Cheers Quote Link to comment Share on other sites More sharing options...
