For instance, if I convert N29E59.HGT to an SDF, I get 29x30x300x301.sdf, when I would expect to get something like 29x30x58x59.sdf or 29x30x59x60.sdf (don't know which is correct).<br /><br />Splat seems to interpret the "flipped" SDF incorrectly as well, since I need to enter in a flipped Anonymoushttps://www.blogger.com/profile/12781529079541538864noreply@blogger.comtag:blogger.com,1999:blog-12974967.post-57448123480826268632013-03-04T16:18:52.257-06:002013-03-04T16:18:52.257-06:00Hi John,

I think that mkstemp() is a standard function in Linux to create temporary folders and files, but not on Windows. I found a workaround was to make my own mkstemp() function to replace it.
