good afternoon Mrs.

we have another little problem, we did the procedure to image L0 to L2 in the SEADAS ok? and the image have some bands and the geographycal information ("LATITUD" and "LONGITUD") we can open the band 678_25 of the image added to this information (LAT and LONG) in MATLAB, but we need open the three things ("LAT", "LONG" and "678_25") together in IDRISI preferably, or in ARCGIS; well then we open the band "678_25" in IDRISI and it ask us the minimum and the maximum X and Y, but we donīt know how do for the software recognize the geographycal information as we can do it in MATLAB.

sorry if the question is very easy... thanks....

Alfredo

Alfredo,

I'm not sure if I understand your question, but I think you are asking how to get the minimum and/or maximum values for the latitude and longitude SDS's.  Here is an example of how to do this at the seadas prompt with the following commands:

SeaDAS> latid = hdf_sd_nametoindex(sd_id,'latitude')
SeaDAS> lat_id = HDF_SD_SELECT(sd_id,latid)
SeaDAS> HDF_SD_GETDATA, lat_id, tmplat
SeaDAS> print,min(tmplat)
      16.9339

If that was not what you wanted to know, please give me some more details on what you want.

Regards, Mark

hi, thanks for your answer. I need know how can open a georeferencing image L2 (georeferencig in SEADAS) in the software IDRISI KILIMANJARO or ARCGIS, I know that the question is simple but, I open this image in this software, and  the image donīt appear with the correct coordinates.

thank you Mrs...
