Semi new to MapTool. Used it briefly about a year ago and loved it. Here's my dilemma: I want to make a zoomable map of an entire Shire roughly 100 by 80 miles. I'd like to zoom into any part of the map for an encounter if necessary. I've seen screen casts of maps done on a planetary scale so I'm pretty sure it's possible. I have no idea how to begin tackling this. I have an image to import, but I'm not sure if that's a good way to go.
I consider myself the master of massive maps, since most of my campaigns use them.
My maps however, span 1 to 2 miles and start to get choppy unless I reuse a lot of the same textures and images. For a fact, you will need to draw your map using textures (make map with maptool drawing tools), since a map made out of premade maps (photoshop, Dundjinni, etc) would simply take up way too much memory at that scale.
I really don't see 100 x 80 miles being possible, but please report back!
Another issue I see is navigating issues when zoomed out. The grid we be set for up close, but what do you expect to happen to that grid when zoomed way out to see the whole shire? Plus I can see it being super annoying zooming out and in. 500 turns of the mouse wheel later... Heh.
But we won't know until you try. Just remember to draw it with as few textures as you can get away with, and when using object or background images, try keeping the number of them to a minimal. In other words, place house1 - house 10, and copy them as much as possible instead of using 300 different and unique house images.
Oh, I did a city once in version 1.2, but it was only like a mile or so, not 100
