Greetings:
I have a 2D gridded data set that I am storing in a NetCDF file and
which I have successfully rendered in IDV. Associated with this data
set are several polylines which must be rendered in the view as well.
So far, I have managed to do this by writing them to writing them to
shapefiles which can be read into IDV. It would be less cumbersome if
I could write the polyline data into the same NetCDF file that
contains the gridded data but I have not yet stumbled upon a
convention that will coerce IDV to recognize the data.
I tried this (and failed):
dimensions:
tdim = 361 ;
... others ...
variables:
double tlat(tdim) ;
tlat:long_name = "latitude" ;
tlat:units = "degrees_north" ;
tlat:axis = "Y" ;
tlat:standard_name = "latitude" ;
double tlon(tdim) ;
tlon:long_name = "longitude" ;
tlon:units = "degrees_east" ;
tlon:axis = "X" ;
tlon:standard_name = "longitude" ;
double term(tdim) ;
term:long_name = "Terminator" ;
term:units = "km" ;
term:coordinates = "tlon tlat" ;
... others ...
(term is just a dummy array containing zeroes)
So, is there a convention for storing simple polylines in NetCDF
files?
Thanks,
