I just received one files with the extension .ras
I´ve tried to open it with 2 recommended softwares (Ayeview and Irfaview), None worked...
The Irfanview software delivers the error message "can´t read header"
I know in advanced the file concernes a Digital Elevation Model.
Does anyone of the map lover knows how to deal with this kind of files?
Can they somehow be opened inArcGis?
Best regards

Interests:I am a Cartographer with varied experience. I work primarily as a freelancer. In my freelancing career I have worked with Maps.com, Designmaps.com, 3dmaps and various other map making and cartography sites.
I have varied software experience, however I use almost all the Cartography and quite a few GIS software, Illustrator, Freehand, Adobe Photoshop and Mapinfo to be precise. I have also worked on Microstation and other Intergraph software including Stereo Photogrammetry on ZI Photo Suites. The other software that I utilize for various other tasks specially 3D realism are Global Mapper and Maprenderer 3D.
Global mapper is a versatile software for various conversion and I found Maprenderer 3D for producing stunning 3D images from height data.
I am available for freelance work, right from mundane line digitisation to Illustrator / Freehand Cartography. Just send me a mail at promapper@gmail.com -

If I am not wrong, this extension applies to SUN SOLARIS bitmap files. I do not know which all software especially Intel / Windows platform which can open them. There would be that big-endian to little endian conversion needed, well I am not sure but could be.I just received one files with the extension .ras

Yes, I believe that ProMapper is right. It's a Sun raster image or grid. My current copy of ArcView ArcMap 9.2 can not read .ras files. But someone with an ArcINFO license might be able to.
Good luck.
