Matthew,
An absolute kludge-type of "solution" would be a) to make sure that the
GeoTIFF is larger than the shapefile when rasterising (in order to not
loose points at the edges) and b) to shift the GeoTIFF NW by 0.5 pixel
after rasterising, as I already wrote in my previous mail.
There has been no traffic on Eli's ticket
http://trac.osgeo.org/gdal/ticket/3774 during the last 11 months, so my
guess is that the bug will remain for a while. It's strange that there
aren't more people stumbling across the issue.

Eli,
I finally got around to looking at the example shapefile and running the same
operation on my machine, and it does indeed seem like the same bug. Thanks for
the good eye, this almost seems like two separate issues; first being the
missing edge points and second being the weird offset. I only say this because
the offset persists even when I set the extents of the output raster as larger
than the input layer.

You may want to look at this ticket and see if it is the same thing. If
so, you can add yourself to the cc list and you will get emails when there are
updates to the ticket. You can also add any additional relevant information to

Hello,
I'm attempting to create a raster from a shapefile of point data, with grid
cells 1 degree square. Although the area I have defined matches up with the
origin coordinates I want, and the grid cells match up with a vector 1-degree
grid I produced in QGIS, the squares supposedly containing the point data are
shifted, it looks like down and to the right. Has anyone encountered this
issue before?
Here is the command I used:
gdal_rasterize -a<column name> -ts 360 180 -te -180 -90 180 90 -l<source layer
name
in source file> <source file> <destination file>
I have uploaded a screenshot of the output I am describing here:

Thanks for any insight,
