Joining maps, so the edges, roads, rivers, etc. match. in 4 parts.
Fractal Terrains to CC3 map very basic instructions in 4 parts. Part 4 can be ignored unless you are using my 184×234 mile map parts template.
Here is how I get around that.
After settling on what template I am going to use, I do a ‘save as’ filename_00001 make a few changes to the map, and then save as to filename_00002 and so forth.
That way if I suddenly realize, and I did this to myself more than once prompting this idea, that I went wrong on my map, and I need to go back 40 or 50 versions. With all of them saved as multiple maps, I can go back. It also allows me the chance to branch off in another direction if I am not satisfied with the mapping direction I am going in.
Of course, when I upload the maps, pngs and web pages to this site, the number on the end is gone. That way even if I wind up drawing over 200 map versions, the viewers never see that number on my site.
(There is another method in the CC2Pro manual. Allyn got me to try it, and it is easy. But I still use this one.)
I started with this large map, I wanted the lower right corner of the island.
Next outline with a hollow rectangle or square, the area you want in the new map.
Use Info->Distance to find the size of the area, place that on the map as a text label, as a reminder.
Do a ‘Save as’ to a different filename as a rectangular bmp.
The rectangular bmp should be the same size as the rectangle described above.
