Opening MODIS files 1647 2
Started by Deleted User
I have problem in opening MOD11A1, land surface temperature, by ENVI 4.2
When I opened files of MOD11A1 by using 'file ->open image file',
only Emis 31, Emis 32 were opened.
MOD11A1 have 12 subitems which can open by using ' file -> open external files ->hdf '.
But when I do so, there are no map infomations.
What should I do

Map Conversion: from sinusoidal to geographic coordinate system NAD83 1589 0
Started by Deleted User
I tried to covert a sinusoidal MODIS data into GCS NAD83 coordinate system. But the conversion does not work correctly. The features are off its locations many pixels. The funny thing is that the same procedure worked fine two months ago.
I am using ENVI 4.2.

texture_cooc_doit 1467 1

in an interactive envi session you can set the gray level quantization when computing coocurrence statistics (texture filtering).
i do not see a keyword in the documentation for setting this parameter when making a call to texture_cooc_doit.

texture measure 1465 1
Started by Deleted User
I am trying to use the occurence and coocurrence statistics calculated by envi (texture filters).
As far as I can tell, these methods use the nodata value as if it were simply a valid value. This seems wrong to me. (For example, any window with just one pixel of nodata value=-32767 will have its mean and all other statistics heavily influenced by such a value.)
Can anyone verify this I'd love any references to why this is the correct thing to do, or alternate strategies for calculating th...

Where is the Dist parameter? 1414 0
Started by Deleted User
I am trying to 'Edit Grid Characteristics' on a grid that I have overlayed on top of my image. I am supposed to be able to 'control the distance of the labels from the edge of the image for each grid type, using the Dist parameter. Larger numbers are farther from the edge.'. But I can't find a Dist parameter under 'Edit Grid Characteristics'.
Any clues Thanks

Error message when save images as big tiff files 1766 1
Started by Deleted User
Hi,
When I try to save an ENVI image as tiff (geotiff) file and the image is bigger (say 500 mb) the software shows an error message. It is something like '....can't allocate memory for the array, result may be invalid....'. Whay is that and is there a way to fix it. Images around 150 mb are save ok.
I use ENVI 4.2
Thanks,
Vasil

Mosaicking DEMs 1182 0

Objective: Mosaick several DEMs, all same size and format (60x60km, DEM/tif), into ENVI with transparent background (set to 0)
Problem: DEM background recurs as opaque (black)
Strategies: Attempted opening DEMs as HDF, not a valid HDF file, therefore, ENVI does not recognize them, unable to manipulate data contained in the header file...

I've encounterd 2 problems with regards to using HDF files:

J’ai besoin vos aides pour un truc de télédétection. En effet j’ai besoin de déterminer les anomalies thermiques dans une zone d’étude pour ma thèse. Mais je ne sais pas comment exploité les information fournis par le canal thermique de l’image Landsat 7.
Pouvais vous me donner la procédure de traitement de ce type d’information à partir des images satellites à l’aide d’ENVI, je serais infiniment reconnaissant pour vos aides.

Email notification bug? 1220 0
Started by Deleted User
This is an issue with the forums, not ENVI directly -- when I receive an email notifying me of changes there isn't a space between the link to follow and 'Thank you...' so my email program (outlook) thinks the 'Thank' is part of the URL:
http://www.ittvis.com/forum/message.aspfmid=1924Thank you for using the Research Systems User Forum!
Can you add in a space after the URL so we can click it within the email and go directly to the right thread Thanks!

Best warping technique for aerial imagery? 1414 0

Quick question: is Delauney triangulation the most appropriate registration technique, since its the only which uses local (as opposed to global) warping, which can account (somewhat) for pitch/yaw/roll issues which cannot be predicted globally Are there other warping techniques available that can do a better job
