I am working on NDVI in ENVI... the output file is in Envi Standard format... I required it in Envi Classification format, which can be done through Envi Edit Header tool... This requirement is for its use in Confusion Matrix using Ground Truth Image... but when i performed this, the resulted NDVI image transformed into BLACK color showing as 'unclassified OR class1' portion (what ever name was suggested at the time of conversion into classification format). (As by the editing header, from standard format to classification, it require at-least 2 classes). I need this to perform Tasseled Cap comparison with NDVI. KINDLY SUGGEST SOMETHING EFFECTIVE.
