Could NCSS handle integrated data with no coverage (integrated point data) ? #1255
Comments
Hi @PBrockmann, As you have checked, the NCSS expects a CDM files with spatial and temporal (?) coverage. You can try to add a geo reference system. For example a 1-dimensional longitude and latitude coordinates with just 1 value on each (i.e. the center of the global bounding-box). Antonio P.S: I haven't test this case with NCSS, when coordinates only contains one-value, therefore feedback it's welcome. |
Hi @cofinoa, In the concerned project, the resource does not include spatial description unfortunately. But in another project, I have indeed be carefull to include a false lon, lat to get rid off this "limitations" and it works. Here is an example that works with 'false' longitude latitude coordinates set to 0. So my purpose would be to change NCSS to be able to handle those cases where describing a longitude, latitude is not relevant. Because spatial integrations are often made on regions defined by shapefiles, define a longitude and a latitude is not very adapted (even if possible by taking the center of the shapefile). Do you thing it could be possible ? |
BTW, the temporal=all seems to be missing in the NCSS interface. Should be another issue, I agree. |
I have a netCDF resource with no coverage metadata (no longitude, latitude) because it contains integrated quantities (global or regional means for example).
In this case, the NCSS complains with
err=Could not open as Coverage
