ESRI ASCII GRIDS: Error reading last line

Reported by: haerta@haerta.de Assigned to: mloskot
Priority: normal Milestone: 1.5.0
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: AAIGrid
Cc: warmerdam

Description (Last modified by mloskot)

When reading ACII Grid files with ncols 1201/nrows 1201 I get the following errors: 

gdalinfo -mm <gridname.grd>:

ERROR 3: Token too long at scanline 1200.
ERROR 1: IReadBlock failed at X offset 0, Y offset 1200

I found out that these errors are reported if the last line of values is not ended with a new line (carriage return/line feed?)

After pressing return key after the last line the file can be read as expected.

It seems that only GDAL has problems with these files.

Mateusz,

I'd appreciate your checking this, and fixing if it still exists. I think it is sufficient to address this in trunk.

I could not reproduce this problem with GDAL from SVN trunk.

I tested it wiht byte.tif.grd file from the autotest package. Last line in this file does not end with LF and/or CR and gdalinfo reports correct results.

I assume this bug has been fixed and closing the ticket.
