I'll add them as soon as I can, which may be a week later than I expected to. We got hit with a blizzard last week (Ohio Valley area of the USA here), and another big snow storm last night and today. I got a call from my uncle asking me to stay here longer because the roads near my house had 9 inches (22.86 cm) of snow on them still.

Have I mentioned that I hate winter in this region? This is so very frustrating.

Here are 18650 tiles of Roanoke, including Hitori's tiles:

The northern part now looks like this:

The Roanoke map is at least 31,500 x 20,600 pixels from what I've already explored. The south edge has an arbitrary border that could probably be turned off later, the north border is unexplored due to darkness, and the west blocked by a huge mountain. I'd guess it could go to at least 50,000 x 50,000 pixels. The full-detail map tiles average about 1.4 bytes per pixel, but you would also want lower-resolution copies for zoomed-out sections and so forth.

I'd allow at least 5 GB for a whole server map at full detail in PNG format. So long as you do the scaling up front and don't rely on the server to do it on the fly, it shouldn't take much processing power to just hand out pre-scaled tiles. If you use JPEGs instead of PNGs it should compress down to more like 200 MB, and smaller still if you don't have the whole map filled in.

Going futher, there's a lot of texture repetition in the map tiles. I'd be unsurprised if you could store the whole accessible map with full detail in 100 MB. Taking advantage of that would require a bit of custom code in the map viewer though.

I am having trouble merging maps. I made two rather large maps, in two game sessions, walking around this mountain blocking the west. After I loaded the two maps into the mapping tool, selected them both, and merged them, the result was incorrect. The two maps were merged compeltely wrong. The program glued them together at a wrong angle, not correct at all

Am I doing something wrong, or is this bugginess of the mapping tool?

You have to find the minimap they have in common and select it on both maps (with CTRL+LMB) as the merging reference point.

I haven't used this map merging tool in question, but I'm a great deal surprised if it doesn't automatically find matching patches. Even the simple approach of calculating a hash for each patch and using that to narrow down a more expensive pixel comparison works fine. (Though you might want to "blacklist" featureless terrain such as deep water)

so long as you have a path going to all explored tiles, you will not have a problem. I am at about 25,000 tiles with no observable errors.

I've moved the map to a different (but still free) host: http://salem.zzl.org/maps.php?james

Roanoke is still uploading, but posting anyway - Plymouth and Jamestown are fully there (well, what I have of them :p). Give it about an hour or so from this post time for Roanoke to be done (7000ish tiles left. Sounds like not much, but they're not the default 100px tiles sizes - thats roughly 28000 tiles worth of map.).
Even with the very slow connection here, this host is much faster at displaying the map. Plus, it doesn't have that stupid 10,000 file limit.

not being able to zoom all the way out makes it somewhat difficult to view the maps.
