[GRASS-user] importing Mars DEM takes too long

[Helmut Kudrnovsky]

>11 seconds can be pretty long depending on the size of the file. Try 
>to convert it to tif and load again, it will be probably much faster. 

the gdal_translated uncompressed geotif has about ~150MB (jp2 ~48 MB).

the import takes about 7 seconds. 

there is some difference in importing time ; maybe cause of compressed vs.
uncompressed. 

it's worth to ask on the GDAL ML about performance of GDAL'S jpeg2000
driver.
