Can't I see netCDF files in ArcCatalog

chiaradorati

I want to add the .nc extension to the ArcCatalog file extension options, so that I can drag and drop .nc files from ArcCatalog. I succesfully added the extension in ArcCatalog 10.4 (Win 8.1 OS) but it doesn't seem to work for ArcCatalog 10.5 (on Win 10 OS): I added the .nc extension as displayed below (already tried with various formats - .nc, .NC, nc, NC...), even restarted the system, but .nc files are still not visible from neither ArcCatalog nor ArcMap. Any help is greatly appreciated.

You cannot add a NetCDF data directly to ArcMap. You need to create a NetCDF Raster layer.

Thanks Jayanta Poddar, I know that there are tools to manipulate and work with netCDF files, but what I mean is to be able to visualize files with .nc extension in the catalog tree in ArcCatalog. It was surely possible until recently (see also the 7th FAQ at the link below related to v. 9.2) Not sure if this functionality has been discontinued or perhaps is a bug of 10.5. As I said it works well with 10.4.

Would be useful to know if others encounter the same problem

Thank you Chiara for the clarification.

Did you add the file extension (.nc) to ArcCatalog options?

Yes!! As stated in my first post, that's exactly what I have done, as it is also shown in the ancillary picture (ArcCatalog > Options > File Types) and in my previous link. But unfortunately it doesn't work for me in ArcCatalog 10.5 under Windows 10 (although, I reiterate, it does in v. 10.4)

chiara dorati‌ - Did you ever solve this? I have the same problem on Win7 with 10.5.

It actually looks like it is by design. I cannot locate it in ArcCatalog nor the ArcMap add data button. Using the "Make Raster Layer" tool (and I assume all other tools), the folder button navigation also does not show it. It says it is invalid if I try to paste the path in or drag it from Windows Explorer.

As Jayanta says above, we need to use the "Make NetCDF Raster Layer". When I run it in ArcCatalog, it is unclear where the layer goes, but it runs without failure. Once I do that, it creates a layer that I can work with in ArcMap. After that, I can drag that layer into other tools. The data > export option in ArcMap works, but if my NetCDF has lots of bands and time slices, that's pretty repetitive.

What did you come up with? Thanks!
