Hetrick" <[log in to unmask]> Susan wants to know about making a globe. I have no idea how the official folks do it but one of the things I did in 7th grade was to make a paper mache globe so I could make it bumpy where the mountains were. Unfortunately, I never figured out how to make the deeps until I was taking cartography some years later. ;-) I blew up a playground ball that was being discarded because they couldn't patch it any more and slathered some Vaseline on it so that the paper wouldn't stick to it. Then, I made the gores out of butcher paper (remember that?!) and traced the land shapes onto them using a gridded copying technique (I remember the hassles of finding my first 1 cm graph paper!). The hardest part was to have a little bit of extra paper on one side of the gore (except for the first (extra on both sides) and last (no extra on either side)). I sort of thought of the joints as seams. When I laid the gores onto the ball, the worst problem was that everything was slippery. So, what I wound up doing was making two almost hemispheres and then joining them after they hardened up. That way, I could let the ball rest on the red Pyrex mixing bowl until the paper mache hardened up. After each hemisphere hardened, I put the mountains on it (they didn't join properly when I joined the hemispheres so I had a few extra miles of mountains! I got an A on the project from Mrs. Baugh. I did the project instead of American history -- even then I was getting bored with the Civil War -- never did get it until I saw the Andersonville cemetery while I was in Atlanta working on my disseration. While I was teaching at UF and the CAM software and database were the up and coming cartographic thing, I remember working out a program to draw the gores on a plotter, but I have no idea where it is now. As I recall, I wound up using the CGS Map Projections book to work out the equations for the program. HTH. vh -- \ / Virginia R.
