Hello,
I would like to create Web Coverage Service from one netCDF file in
following http://mapserver.gis.umn.edu/docs/howto/WCSServerFormatHowTo
My netCDF store rainfall matrix every five minutes in the "pluie"
variable. This the CDL :
dimensions:
time = UNLIMITED; // (496 currently) // (has coord.var)
x = 50; // (has coord.var)
y = 50; // (has coord.var)
variables:
int Lambert_Conformal;
:grid_mapping_name = "lambert_conformal_conic";
:standard_parallel = 43.20317, 44.99683; // double
:longitude_of_central_meridian = 2.337229; // double
:latitude_of_projection_origin = 44.1; // double
:false_easting = 600.0; // double
:false_northing = 3200.0; // double
:_CoordinateTransformType = "Projection";
:_CoordinateSystems = "ProjectionCoordinateSystem";
:_CoordinateAxes = "y x";
:_CoordinateAxisTypes = "GeoX GeoY";
* double pluie(time=496, y=50, x=50);*
* :units = "mm/h";*
* :long_name = "Intensité de pluie";*
* :coordinates = "lat lon";*
* :grid_mapping = "Lambert_Conformal";*
* :_CoordinateSystems = "ProjectionCoordinateSystem
LatLonCoordinateSystem";*
Vincent,
Because GDAL treats this array as a single dataset having 496 bands, I don't
believe there is a way to properly create a tileindex with one entry per
time slice, referring back directly to that band though this is something that
I think was discussed at one point.
You *can* serve the pluie array, but it will be represented as having 496
bands along a dimension called Band instead of time.
Hopefully Steve will correct me if I am wrong. What would be nice
is a way to have WCS (and raster rendering in general) potentially
override the BANDS= processing option with information read from a
tile index, and then update the gdaltindex program accordingly to
generate such results. This shouldn't - in theory - be too hard to
implement.
Best regards,
