Hi all,<br>
<br>
I’m trying to save geotiff rasters as tiled with custom blocksize. I'm using the<br>
python interface for this.<br>
<br>
Hence I use the following options:<br>
options = ["TILED = YES", "BLOCKXSIZE = 128", "BLOCKYSIZE = 128"]<br>
<br>
that I then pass on to the raster creation:<br>
dst_ds = raster.Create( filename,<br>
self.width,<br>
self.height,<br>
3,<br>
gdal.GDT_Byte,<br>
options)<br>
<br>
The code does not create any error and a readable tif is generated.<br>
However, I cannot see using tiffdump or tiffinfo any information on the tiling:<br>
<br>
TIFF Directory at offset 0x6fdf5a (7331674)<br>
Image Width: 2560 Image Length: 2048<br>
Bits/Sample: 8<br>
Sample Format: unsigned integer<br>
Compression Scheme: AdobeDeflate<br>
Photometric Interpretation: RGB color<br>
Samples/Pixel: 3<br>
Rows/Strip: 1<br>
Planar Configuration: single image plane<br>

Tag 33550: 3000.000000,3000.000000,0.000000<br>
Tag 33922: 0.000000,0.000000,0.000000,-3780000.000000,-1500000.000000,0.000000<br>
Tag 34735:<br>
1,1,0,5,1024,0,1,2,1025,0,1,1,2048,0,1,4326,2049,34737,7,0,2054,0,1,9102<br>
Tag 34737: WGS 84|<br>
<br>
Hence my questions:<br>
- - How do I check that the resulting tif image is tiled ?<br>
- - Do I need to specify TIFFTAG_TILELENGTH and TIFFTAG_TILEWIDTH ?<br>
<br>
<br>
Thanks !<br>
