Hello!
I'm using Idrisi Taiga and I'm attempting to use the MAXLIKE classification. I created the .sig file with MAKESIG but when I try to execute the classification I keep getting an error message ''error 13.sig not found''.
Any suggestions how to get rid of this problem?
Thank you for your help,
Jane
Hi Jane and All,
I have a similar problem: I would like to create the signature file for MAXLIKE classification, but get an error message: "Unexpected error condition encountered. Please check the integrity of the operation performed, the data used, and the amount of disk space available."
Idrisi Selva: Module MAKESIG
I have three images in a raster group file (3 bands), which I would like to use for deriving spectral signatures.
After creating my training_site.vct file (for MAXLIKE classification), and creating the SGF file, following the standard input as required by the MAKESIG module, I get the error above. It appears some the habitat_class.sig files get created, but have no information stored in them (regarding mean, max, min, var, covar, etc).
Data are real number between 0 and 2.
I have removed all outliers, plotted images as histograms and checked for aprox normal distribution. I cannot find the problem. Has anyone else had this problem, or know how to fix it.
Bests
Phil
Dear Jane and all,
When you make your signature filenames: make sure that these have no spaces or special characters in the names.
e.g. "deep_sand_5-10m" and NOT "deep sand (5 - 10m)"
I have posted a query with regards to a failure message when running MAKESIG, and this seems to have resolved it.
Kind regards
Phil
Hello!
Respected Sir/Mam,
while executing Idrisi Image processing. I tried to create a sig file. But when I execute max like it popup and reported an error " Ms.sig 0 not found". I followed the rules but the results are the same. How to solve it.
Hello!
Respected Sir/Mam,
Can we add bands different than 3,4,5 as for Landsat 07 images? Can we Extract by mask bands according to our area before entering it into TerrSet?
Please share details regarding the selection of no of the band for Landsat 07 and 08. Do we enter (3,4,5) the same band for both or differ.
