Greetings,

I am trying to open a few SDTS format "DDF" files that I obtained from a few different sources.  Each time to try to add the DDF files into an ArcMap session I get an error..."Invalid Raster File".  Here is a screen shot...

I know that ArcMap is capable of opening these files and have found no solutions in the forums, any advice is appreciated.

Bill,

Copy the raster to a new directory through ArcCatalog. Open windows explorer and browse to the new directory and delete .aux file. Add the raster to ArcMap.

Nidhin,

Thanks for the response but I am not able to copy the file in ArcCatalog and when I copy the enclosing folder, none of the files visible in the File Manager are ".aux".  The files originated from the USGS EarthExplorer site and I generated a bulk download that came in as "XXXX.stds.tar.gz".  I opened the GZ archive using 7-Zip and then extracted the TAR files to end up with a folder containing a bunch of ".DDF" files.  None of the DDFs are able to be previewed or opened in ArcCatalog and I cannot see any vector files which is what I am looking for in the first place.  I do get the following error when I extract the TAR files...

Is there a special process for extracting a TAR.GZ file other than what I have described?

Not sure if you'll be able to access this but here is the path for one of the files I tried to download...

Thanks for taking the time to respond.

Bill,

I had downloaded the data from USGS and I was able to reproduce the issue. There was an option in previous release of ArcGIS (SDTS to Raster tool). It was available till ArcGIS Desktop 9.3. You can either process it using any third party software or you have to contact ESRI Tech Support.

Thanks for following up and taking the time to recreate the problem. 
I'll check with ESRI about that tool.

Kind regards,


Bill
