[McIDAS #IGK-131677]: Accessing a local set of GOES 16 nc files.



Hi Stonie,

re;

No worries.

Yup, McIDAS can definitely be used to re-project (McIDAS terms it remapping)
images.  The College of DuPage (COD) NEXLAB site uses Unidata McIDAS-X
to remap the CONUS images that are received in the GOES-R fixed grid
projection into the Lambert Conformal projection that users had long
used in the GINI images being sent in NOAAPort.

McIDAS will not/does not composite the tiles into full scenes.  Ryan
May wrote a Python script that stitches together the tiles; his code
is available in the ldm-alchemy section of the Unidata area of GitHub.

This can be done, but the server that handles the tiles and/or reconstituted
images is of type SCMI, not ABIN.  Since you are stripping off the NOAAPort
broadcast header and footer, you should be able to use the resulting tiles
as elements in a McIDAS ADDE dataset.  Again, McIDAS will NOT stitch the
tiles together for you, so each element of the dataset would be an individual
tile.  This functionality is available in Unidata McIDAS-X v2018x.

Unidata McIDAS-X v2019 contains the work I did to combine serving of the
NOAAPort and GRB delivered GOES-16/17 imagery.

My comment about the NIMAGE IDD feed was to make sure that you knew that
we are doing the work of stitching together NOAAPort tiles and sending
out the resulting full scenes in a format that is readily usable by
a variety of application packages including AWIPS, GEMPAK, IDV/McIDAS-V
and McIDAS-X.

OK.

re:

Again, you can try things out using Unidata McIDAS-X v2018x, but you have to
change the ADDE dataset definition to use SCMI as the type instead of ABIN.
I will make an announcement to the address@hidden email list
as soon as Unidata McIDAS v2019 is available for download.

Cheers,

Tom
