How To Montage Too Many Google Map Tiles?
Posted: 2013-08-17T07:50:56-07:00
What i have done:
1. Download google tiles
each file(=tile) is 256 pixel * 256 pixel , png/jpg format
2. use Montage command line ( windows 7 64bit platform)
2.1 My first try: amount is 1024(=32*32, 32 col * 32 row): -->successful
I used 2 steps to combine 1024 tiles into 1 tiff, this works fine
montage Somefolder\*.jpg -geometry 256x256 -tile 1x32 Somefolder\MuliPage.tiff
montage Somefolder\1.tiff -geometry +0+0 -tile 32x1 Somefolder\Combined.tiff
2.2 My second try: amount is 4096(64*64, 64 col * 64 row) --->Failed
montage Somefolder\*.jpg -geometry 256x256 -tile 1x64 Somefolder\MuliPage.tiff
this command just generates nothing, or something told me Memory Allocation Failed.
3. List my resources
i found some pages in the forum,so i list my resources
File Area Memory Map Disk Thread Throttle Time
--------------------------------------------------------------------------------
1536 8.515GB 3.9651GiB 7.9302GiB unlimited 2 0 unlimited
So ,i guess the 1st try is success as my file maximum is 1536.
4. What could i do to montage >1536 files? Thanks
