I have been working on this issue for some time and the driver has a
quirky way of handling spatial reference parameters. If a tag is not
present, the netCDFDataset::FetchCopyParms() function returns a default
value. Currently, those default values are all specified as 0.0. Because of this, there is no error and my projection is set with several 0.0 values. I have fixed the standard parallel issue on my local machine and it now supports CF-1 tags(standard_parallel) as well as gdal tags (standard_parallel_1 and standard_parallel_2)</font>. <span style="font-family: courier new,monospace;">I would like to continue to update the driver for other tags that have been added to CF, but still support gdal tags as well, but I am not sure if my programming methods will be suitable. I would hate to do a bunch of work and not be able to incorporate it. Any thoughts on how to go about this?<br>

After a little digging, it appears that the netCDF driver does not support the tag:<br>
<br>
Lambert_Conformal:standard_parallel<br>
<br>
it supports:<br>
Lambert_Conformal:standard_parallel_1<br>
and:<br>
Lambert_Conformal:standard_parallel_2<br>
<br>
I am not sure if the tag is out of specification, or if the driver needs to be updated. I also notice OGRSpatialReference has a separate function for setting a Lambert Conformal Conic with single parallel:<br>
<br>
OGRErr SetLCC1SP( *double* dfCenterLat, *double* dfCenterLong, ...<br>
<br>
but this is not referenced in the netCDF driver.<br>
<br>
So, my next question is:<br>
Can you specify the value of SP_1 and SP_2 as the same parallel in the standard LCC, or do you have to set LCC1SP<br>
<br>
Thanks everyone for your patience,<br>

Good investigating. I'd suggest filing a ticket, ideally referencing<br>
an example file. It should be fairly easily added.<br>
