Ahamann Posted November 23, 2011 Report Share Posted November 23, 2011 I tried to eliminate the clouds - but i get the error "strange hot histogramm haze ..." - is there something strange with my image or with the calibration data? i created the calibration data by myself but i think thats correct... Any Idea? Quote Link to comment Share on other sites More sharing options...

Ahamann Posted November 23, 2011 Author Report Share Posted November 23, 2011 ok, it was not well defined - i want not eliminate the clouds, i want to reduce these... I use Atcor 2 and my images did i create from landsat data. (Landsat TM 5). -> http://glcf.umd.edu/data/landsat/ downloaded all bands(tiff) and created an image file. based on the date, i made my calibration file with bias and gain. thats all, what i can say - no big deal Quote Link to comment Share on other sites More sharing options...
nulanil Posted October 22, 2012 Report Share Posted October 22, 2012 Hi... "strange HOT histo... bla... bla..." error message is cz your composite images have different dimensions (band 1, 2, etc). To resolve: 1. ERDAS viewer: Open all band images 2. Create AOI layer at least on intersection area of band 1 - 7 images 3. Resample each band covered by AOI layer (NN method, ignore zero, let pixel size as an original size, dont forget to add AOI layer) 4. Now u have band 1, 2,... etc with same dimension = AOI dimension 5. Run ATCOR ..... If u are using 1 scene landsat... the error msg is: "array... bla... bla..." probably To resolve this error.... create 1 scne landsat --> 4 tiles Cheers...
