Re: [gdal-dev] GRIB2 file produces None on opening
Just a comment: There are some grib files generated by SPRING that are not compatible with the GRIB driver. It might be a version issue GRIB1, GRIB2 or something. Ex.: C:\Data\SpringDB\SP\SPaulogdalinfo I000355.grb ERROR 4: `I000355.grb' not recognised as a supported file format. gdalinfo failed - unable to open 'I000355.grb'.

Re: [gdal-dev] GRIB2 file produces None on opening
Hi: I have the same problem. I just installed 1.5.2 version on Linux. When I do: gdalinfo --formats | grep GRIB Nothing came out. Also when I do: gdalinfo abc.grb I got: not recognised as a supported file format My grb file is GRIB2 format. Do we need to download the GRIB driver before the installation?

[gdal-dev] Disabiling Geos messages via OGR
I'm using OGR's Geos functions (e.g. OGRGeometry::IsValid) to process some polygons. Geos spits out messages to console (stderr?) like Warning 1: Self-intersection at or near point Is there a way to disable these messages via OGR? Thanks!

Re: [gdal-dev] Guidance sought on using gdal-translate
On Fri, Aug 15, 2008 at 8:41 AM, Christopher Hunt [EMAIL PROTECTED] wrote: Hi again Frank et. al, I've made some progress. The aerial image provider now tells me that it is projected as OSGB 1936 which I believe is EPSG:27700. Thus if I use a command like: gdal_translate -a_srs EPSG:27700 -a_ullr then I should be able to create my GeoTIFF. Unfortunately the image provider hasn't provided the top left/bottom right coords so I'm going to Google Earth to approximate them (yes, ugly I know). I'm hopeful that the actual top left/bottom right will ultimately be provided to me, but meanwhile I want to ensure that the a_ullr parameters I provide will be in metres i.e. eastings and northings from the OSGB 1936 origin. Is this correct? Chris, I believe EPSG:27700 is British National Grid which is a projected coordinate system based on the OSGB 1936 datum. So you should ensure the provider means the dataset is actually in BNG, in addition to being based on OSGB 1936. If you can get BNG coordinates then that is great. If you can only get WGS84 or OSGB1936 lat/long coordinates then you can convert these to BNG using a program like cs2cs though that is a bit tricky.
