Comparing maps

 

Eva Jurenikova wrote about 25-manna (a big relay in Sweden) and posted her map.

25-Manna is a fun race and I've got a lot of fond memories of it. I ran it 3 times (I think) and the weather was always nice (cool, but not cold, and dry). I also had a very good race the last time I ran it and got to bring my team up to first place after 16 legs. We couldn't hang on to it over the last nine legs and dropped down to 8th. I think it was the one and only time I've been in the lead of a relay at the exchange. It is a nice feeling.

Anyway, back to this year's 25-Manna....

I was looking at Jurenikova's routes and recognized the terrain. I dug around in my old maps and found two copies of the same area from events I ran there in 1991.

"Cool, it'll be interesting to compare the maps -- see how mapping has changed," I thought.

Actually, it wasn't interesting. The 1991 map and the 2005 maps are nearly the same. I found very few differences. The clip below (of the 1991 map) shows the area that is most different. The only significant difference in the clip is that the 1991 map used fewer form lines.
