The -ps parameter specifies the pixel width and pixel height of a
tile. You must multiply these values.
-ps 1000 1000
means 1000x1000 = 1 million pixels for each tile
As a consequence, a tile needs 1 MB .. n MB , depending on your color
model. The file size of the tiles my be smaller if compression is
used. (e. g. png), but in memory during calculations, the raster data
is uncompressed.
Quoting Tacot <[email protected]>:
Hi,
Why do you talk about million pixels?
I'm trying now with this command:
gdal_retile -of ECW -ps 1000 1000 -targetDir C:\GDAL\ECW Image.ecw
It's not finished yet, but there's so many tiles!!
I thought maybe using gdalbuildvrt, it could be a possibility.
