[Tcl-nap-users] Two issues : gdal +binary data

[salah j. <s_...@ya...>]

Hi Guys
   
  Since NAP is an array processor, and i think it is originally designed to support images is there is any way to support GDAL format.
   
  I GDAL my images and convert them to ASCII or HDF image file and after that make my manipulation, and this is an extra process.
   
  second issue:
   
  I create NAOs objects out of quick bird image and i did a comparison between the time needed to create NAO out of ASCII and out of HDF
   
  i create 8 images 4 in ASCII and 4 in HDF  "each band in an image" and  i got this result.
            Image Name
    N_cols
    Nrows
    Data type
    origen
    Size ascii
    Size HDF
    Time ASCII
    Time HDF
    Diff

    236.857

   
  is my result is ok...?, now i am wondering why creating NAO out of HDF files is more expensive than creating it out of ASCII.
