Interesting tutorial video on using Open Orienteering Mapper:

I'm pretty sure he made a couple of mistakes. First, I think he put 18S in as UTM zone when it should have been 18N. Second, I think he used 10.?? for declination when he should have used -10.??. I'm not sure about the photos, but I haven't had to adjust those. Instead, I just open them with an associated world file and they pop into place (maybe the wrong UTM zone would cause that trouble).
Oh, and there's got to be a better way to use USGS maps for base contours than using the map as an image and just adjusting it.
If I get inspired, I'll watch it and pay more attention to see if the things that look like mistakes are mistakes.
Also, would be interesting to use Lidar data for contours, but that just adds another layer of complexity to a short tutorial.
Also, he draws lots of straight line segments instead of curves. That doesn't seem very good.
