CGGEOMOSAIC

CGGEOMOSAIC
  Creates a mosaic or combination image, given the names of two GeoTiff image files.
  The images must be 2D images.
 

Categories


    Map Utilities
   

Returns


    The name of a GeoTiff image file containing the combined image mosaic.
   

Params


    geofile_1: in, required, type=string
        The name of the first GeoTiff file to be combined into a mosaic.
        Currently the code only works with 2D images.
    geofile_2: in, required, type=string
        The name of the second GeoTiff file to be combined into a mosaic.
        Currently the code only works with 2D images.
     

Keywords


    filename: in, optional, type=string
        The name of the output GeoTiff file. If not provided, the user will
        be asked to create a name. If provided, the user will not be prompted
        and this name will be used.
    imageout: out, optional, type=varies
        The final image mosaic.
    mapout: out, optional, type=object
        A map coordinate object (cgMap) that geolocates the new image mosaic.
    missing: in, optional, type=varies
        The missing value in the input images. If scalar value, the same value is used
        for both images, but may be a two-element array.
    miss_out: in, optional, type=varies
        The missing value of the output image. If undefined, missing[0] is used. If
        missing[0] is undefined, the value 0B is used.
    palette: in, optional
        A 256x3 array containing the R, G, and B color vectors with which the image
        should be displayed. The palette will be stored with the mosaiced image. If
        this is not supplied, and either of the other images have a palette, it will be
        used instead. Images are checked for palettes in the order they are supplied
        to the function.
    success: out, optional, type=boolean
        This keyword is set to 1 if the function completed successfully. And to
        0 otherwise.

History


    Change History::
        Written, 18 August 2012. DWF.
        Added SUCCESS keyword 4 September 2012. DWF.
        Now blending overlap regions using 50% of pixel values from the two images. 14 Sept 2012. DWF.
        Revamp of algorithm's handing of missing values. Added MISS_OUT keyword and removed HISTOMATCH
          keyword because it only works for BYTE data. Restricted mosaicking to 2D images. 29 Jan 2013. DWF.
        Added PALETTE keyword and changed algoritm to use color palettes if available. 21 Nov 2013. DWF.
