Project
Enter data for a newly opened hospital in Spotsylvania, VA USA. It's a big problem because the "big" mappers have old images that just show trees! When people try to get directions, the routing takes them 10-20 minutes out of their way. This can be a problem when lives and outcomes are at stake. Help and encouragement would be appreciated. I'm doing this as a volunteer just to help save lives and reduce/prevent suffering. I figure once I enter the data, the big mappers can import it into their databases. I may be naive in that assumption.

Equipment
I have a TomTom XL that I installed Tripmaster V3.1 on. Getting good verifiable traces when walking. However when driving, the results can get pretty inconsistent. There's probably some settings that one could tweak when doing driving runs, but I'm not yet up to speed on the software.

Mapping aids
I have a detailed to scale site map in PDF I can trace. Haven't yet figured out how to import it and scale it to fit. I could probably cheat and simply display it on the screen, take a screen shot, and then save to tif, jpg, bmp, or whatever is most friendly for OSM. Again I'm new at this and don't want to reinvent the wheel or start doing things the hard way when some of the pros with a few "do this" and "look at that" helps can point me in the right direction.

Happy mapping...
