DEM loading difficulties

Recommended Posts

I have a DEM that is in a Geodatabase raster dataset (file type). From what I can tell, I'm only able to bring it in using the GIS module in that format -- and then it is simply an image, not an elevation dataset.

I need to clip the DEM anyways (a lot larger than needed for my model), so I converted it in ArcMap to a ASCII file. When I tried to bring it in to SMS as that file, it either wouldn't load properly or crashed -- possibly because I wasn't using the correct file type.

So I plan to now convert the raster to an xyz file. Is there a better way to do this? Or am I missing the correct file type when bringing it in as a ASCII?

Also, do you always have to enable ArcObjects in SMS before opening an SMS file with GIS objects? If I don't, the file will only open the non-GIS datasets in my file.

Thanks!

Nicki,

What version of SMS are you using? The SMS 11.0 beta now has a raster module and can read in many different formats, look in the SMS 11.0 beta help file for more info. If you are using version SMS 10.1 then the simplest thing to do would be to convert it to an xyz and import it in as a scatter set.

To answer your second question, there are certain GIS items that can be read in without "enable ArcObjects" checked, but it is limited. SMS does not automatically check this (would be nice if it did) and so yes you would have to enable it before you read in the file. The reason behind this is if you gave your files to someone who did not have ArcGIS, it would still be able to open. I would send an email to tech support and ask them to add this as a feature request.

Cheers,

Cameron

Thanks! I was able to bring it in as an XYZ, but I'll check out the 11.0 beta version.
