[postgis-users] importing Raster with wkt raster

[Steve.Toutant at inspq.qc.ca]

Hi,
I tried importing a tif using wktraster. I used this as an example
http://mateusz.loskot.net/2009/03/30/crunching-wkt-rasters/

1-
I don't understand the use of -m parameters in the example. this option 
doesn't exist in gdal2wktraster.py -h

2-
I need more information on how to use properly the -k option. Blocksize is 
it the Size of the image or should I enter the pixel size

Here is the syntax I used and below the gdalinfo of my .TIF
Can you please tell if I'm importing the raster properly?


gdal2wktraster.py -r estMtl.tif -t estMtl_tif_32198 -s 32198 -o wkt.sql -k 
30x30

Here is the gdalinfo of the .tif
