Hi, I would try to use TILEINDEX through OGR but that gets tricky because one LAYER probable can't have two CONNECTIONTYPEs. Perhaps it would work by using a tileindex layer as a tileindex for contours.
LAYER #OGR tileindex layer NAME "ogr_tileindex" CONNECTIONTYPE OGR CONNECTION .... ... ... LAYER #countour layer TILEINDEX "ogr_tileindex" CONNECTIONTYPE CONTOUR PROCESSING "BAND=1" .... .... But based on the error message Mapserver tries already open your GRIB2 files through GDAL/OGR. Are you sure that you have valid path in the "location" field of the tileindex shape? -Jukka Rahkonen- Kralidis, Tom wrote: Hi all: using 6.4.1 we are attempting to display (via WMS) GRIB2 data as a contour layer backed by a tileindex setup. Invoking a basic WMS 1.3.0 GetMap request returns the following ServiceExceptionReport: msDrawMap(): Image handling error. Failed to draw layer named 'RDPS.ETA_PN'. msContourLayerOpen(): Image handling error. Unable to open GDAL dataset. msBuildPath: Unable to access file. msBuildPath: Unable to access file. msContourLayerSetTimeFilter(): General error message. Assertion failed: Contour layer not opened!!! When I point directly to a single GRIB2 file (via the DATA directive), all works as expected. Layer definition snippet below. Any idea what I'm doing wrong here? Or whether this is a suitable workaround? Note we are bound to UbuntuGIS stable.
