gdal_translate error

[vijayansiva]

hi,

I am using GDAL for conversion from PDS to tiff format, but there is a problem. While using gdal_translate the original image was split into two. The projection is applied to the image but the coordinates are also not in agreement with the header file. Can any one help me in this regard.

The original image and supporting files

correct image should look like

After conversion the image was shifted to right side and looks like

split into two. How to short it out and get like original image.

hi,

herewith i am giving the correct link to download the pds image. When applying gdal_translate the image is shifted to the right. (the problem is with file which contained multiple entries for a number of rows and column in the image.)

hi,

i want to convert a PDS image to geotiff. if i use gdal_translate it is splitting image into two. there is some problem in image header (hope so- that is the image contains multiple entries for a number of rows and column)

help me to solve this problem

I have downloaded the last rar and examined the image. It is unconventional in that it has RECORD_TYPE of UNDEFINED and the RECORD_BYTES field is missing, and the ^{IMAGE is expressed in <BYTES> instead of records.}

The lack of a RECORD_BYTES actually was causing a crash with the latest code (likely true of GDAL 1.7.2), which had some recent dependency added on this field.

I think I have made appropriate adjustments for these various problems and now the image works well with trunk. The changes are in trunk (r19662) and 1.7 (r19663).

Let me know if a problem persists with this latest code.

hi,

The image attached in the link (.img) is split into two if i use gdal_translate to convert from pds to tif format. I made the changes in trunk 1.7(r19663) but still my image is split into two. As i am new to GDAL i need help on this issue to obtain the correct image.

note: the image loads correctly if i open it in ENVI; if i do gdal_translate and open it shows the splited image.

I have tried the latest trunk and 1.7 branch code on the provided file, and the resulting image looks fine. Can you try with the snapshot code from the 1.7 branch (or trunk) and see if you still have the problem?

There have been multiple fixes in the PDS code in recent months and I wonder if you have them all.

hi,

still there is problem for me in getting the correct image. Could you explain me little bit more how to make changes and run the file ( i am using gdal with FWtools2.4.7).

herewith i had attached the image which i got while using gdal_translate.

hi,

try gdal_translate for the below given image (link) from pds to tif, the image was shifted to right and splitted.

​http://hotfile.com/dl/44006714/952f8d0/DTMTCO_02_01731N239E3144SC.rar.html

How to fix it explain me as i am new to gdal. I made the changes in trunk 1.7(r19663) but still problem. I dont know whether the changes made in trunk is correct or not. So tell me how to make changes in trunk(r29663) and how to execute it.

Download at ​http://download.osgeo.org/gdal/daily/ one of the source packages (either trunk = dev version or stable = 1.7). Or if you're working on Windows, you can also directly use one of the daily binary builds at : ​http://vbkto.dyndns.org:1280/sdk/Default.aspx
