I think the "Unknown error" might be a "not enough memory" type of error. I am now trying a different process:
- I am combining all the files except the elevation files to generate intermediate .MP files. This process seems to work OK. I have now generated the MP files where before I got my 'Unknown error'. So we know the "Unknown error" is not because of bizarre data in the GNIS/Transportation/etc files.
- When this is done I will combine the .MP files above with the elevation data to generate the final MP files.
This process will use less memory because when I bring in the elevation data (already split in smaller rectangles) I won't have in memory all the GNIS/Transportation/Water/etc files already loaded.
From what I can see, it looks like GM loads only the files it needs.
Stay tuned...
I took a look around the GM forum and it would appear that most likely that is a memory. I think it tops out at 2gigs in 32bit windows but can use up to 4 gigs in 64bit.
Perhaps look at the coordinates of the pieces missing and and export them from GM via lat/lon bounds to those coordinates?
