Mapping 2:00:00 [1] *** +100m
Spent 4 hours mapping a little 4H camp near Clarksville, Ohio. A guy I work with volunteers there, and he's been doing compass course stuff. The camp starts tomorrow (Sunday), and I'm trying to get him something usable by Monday afternoon. I got a basemap with 4-foot (1.25m) contours and a really nice aerial .jpg from the county GIS department. I told them what it was for, and they just e-mailed me the data I needed---free. The contours are sometimes good, sometimes not-so-good. The area will fit on a letter-size (A4-ish) map at 1:4000, which means it's really small. I'll probably use 1:5000 and try to get 2 on a page. I've been looking at the 5m contours (every 4th), and I think 2.5m might be better. It might even be neat to use 1.25m---I'll go check the ISSOM. I mapped the main areas, and every decent trail I could fine, and I didn't map streams, or vegetation in the woods. I did change a tiny number of contours.
From looking at the basemap, I expected it to be hideously steep (if you did the US Champs Relay this year, you know what I mean), but I was really surprised. If I can find some mappable features on some of these slopes, it might be an awesome little map.
I had a lot of trouble mapping today. Because I got the GIS data sort of late Friday, I didn't have time to perfect my aerial photo/basemap. I made the basemap lines too thick, and made the aerial photo way too dim. Plus, I dinked around with the scale as long as I could before I had to print something, and I went into the field with an unknown scale on my fieldwork. I realized about halfway through that I needed to draw longer lines as I added trails. I carried a good copy of the aerial, and that helped a lot, but some of the trails far from recognizable features might be a little...off.
One good thing---A lot more runnable forest than I expected. A lot of medium and third green, though.
Great day in the woods.
