This is an actual real digital elevation model (dem) of Mars South pole. I can't claim anything except I found it on the web. Use and abuse freely. The zipped file is a little over 7k zipped and the limit here is 5k. so I can't post it ....if you want it send me your e-mail and its yours....Thanks!
