Adam,
At a high level, we have a team that works closely with NATO. They keep track of relevant STANAGs, and work to get support them in the ArcGIS Platform. On your specific ones:
- 4545 - NSIF - We support this with the NITF for ArcGIS Extension - http://www.esri.com/industries/defense/nitf
- 7023 - I don't have information on support for this one
- 4607 - Nothing out of the box, but customers have integrated GMTI using this standard with ArcGIS.
- 4609 - FMV add-in fully supports MISB data that adheres to the standard outlined in STANAG 4609. However, we have not yet integrated our FMV add-in with Runtime. Our next release will be to integrate it with ArcGIS Pro in addition to ArcMap. Then we will tackle integration with Runtime, but that is probably not until next year to have something released.
Creation of custom symbol dictionaries is planned to be supported for Runtime Update 100.2 later this year. With Runtime Update 100.1, we are planning on releasing an APP-6(B) style file through the proper channels with NATO. We will make an announcement with more details once this is ready.
I hope this helps.
Thank you,
Gary
