Hello everyone,
I am trying to create a store with a netcdf file that has 3 dimensions:
longitude, latitude and time. The file works great in QGIS or Panoply, or
when I inspect it in python or with ncdump. The output of the ncdump of my
file is the following:
netcdf eccc_winds {
dimensions:
time = UNLIMITED ; // (49 currently)
lat = 700 ;
lon = 1000 ;
variables:
float lon(lon) ;
lon:units = "degrees" ;
lon:long_name = "longitude" ;
lon:standard_name = "longitude" ;
float lat(lat) ;
lat:units = "degrees_north" ;
lat:long_name = "latitude" ;
lat:standard_name = "latitude" ;
double time(time) ;
time:units = "hours since 1970-01-01 00:00" ;
time:long_name = "time" ;
time:standard_name = "time" ;
float WDIR_TGL_10(time, lat, lon) ;
WDIR_TGL_10:units = "degree" ;
WDIR_TGL_10:long_name = "wind_from_direction" ;
float WIND_TGL_10(time, lat, lon) ;
WIND_TGL_10:units = "m/s" ;
WIND_TGL_10:long_name = "wind_speed" ;
However, when I try to add it as a store on geoserver, I get the error
"Caused by: org.geotools.data.DataSourceException:
java.lang.IllegalArgumentException: Number of Images is negative: 0" (you
can see the full log below).
Anyone knows what it means?
Thanks a lot for you time!
Julien
