After seeing a post about importing DEM'S into Bryce. I thought I would give it a try. Does anyone know where I can find Dem maps of Canada, downloadable. I have searched all over and found one or two sites and you have to buy them- unbelievable. Also in the previous post there was mention of changing file names to .dem, and also was a link to a tutorial for converting sts and dems to grayscale. I downloaded a dem zip went through all the procedures to convert it including the 3'rd party software and I could only get one to convert to grayscale. However I was just playing around and used file import object and just imported a dem without converting it in anyway. It worked, so it's got me wondering why do you have to convert it or change filenames at all. Am I missing something, or me being a newbie to Bryce am I asking a silly question? Any help in clearing this up would be appreciated, thanks
