Description Shear an ASTER IR image so the plaid is relatively horizontal. Then use thm.deplaid to clean up the image
Arguments and Return Values Arguments: ASTER IR image array Return Value: A clean ASTER IR image array
Usage Syntax: deplaid_aster(image [,ignore=FLOAT][,rectify=BOOL]) image - data array containing an ASTEr IR image from load_aster() path of the ASTER HDF ignore - ignore value for the blackspace rectify - use rectify instead of shearing (this is required for projected and not camera coordinate ASTER data. NOTE: Many values are hard coded for ASTER images at the native resolution. Use thm.deplaid() for more generic applications This function requires davinci 2.10
