FGDC endorses five standards

These standards are now listed as FGDC endorsed standards: see https://www.fgdc.gov/standards/fgdc-endorsed-external-standards/index_html
The five standards are: 

  1. Aeronautical Information Exchange Model (AIXM) 5.1
  2. ISO/IEC 15444-1:2004 Technical Corrigenda 1:2007 and 2:2008 JPEG 2000
  3. OGC GeoPackage 1.0
  4. Geopolitical Entities, Names, and Codes (GENC) Standard Edition 2
  5. GeoRSS-Simple and GeoRSS-GML

Aeronautical Information Exchange Model(AIXM) 5.1

AIXM 5.1 is a standard exchange format containing hundreds of entities, data types, and relationships used to represent aeronautical data. It is based on International Civil Aviation Organization (ICAO) standards and recommended practices and industry standards requirements for digital data exchange and GIS capability.  It provides a mechanism to exchange information applicable to aerodromes (airports), heliports, routes, navigation aids, fixes, instrument approach procedures, instrument departures, standard terminal arrival routes, organizations, units, services, obstacles and airspace.  

AIXM uses Geography Markup Language (GML) to leverage existing commercial-off-the-shelf (COTS) tools as well as web services. Its conceptual model uses the Unified Modeling Language (UML) to define the relationships, behavior, and high level ideas for aeronautical data. 

AIXM 5 was initially developed by the US Federal Aviation Administration (FAA) and the European Organisation for the Safety of Air Navigation (EUROCONTROL) with support from the international community.  

There are no restrictions, limitations, or other constraints that affect promulgation/adoption/implementation of AIXM 5.1.  AIXM 5.1 may be downloaded at no cost from http://www.aixm.aero/public/standard_page/download.html.  

ISO/IEC 15444-1:2004 Technical Corrigenda 1:2007 and 2:2008 JPEG 2000 

ISO/IEC 15444-1:2004 Technical Corrigenda 1:2007 and 2:2008 JPEG 2000 serve as errata for ISO/IEC 15444-1:2014, Information technology -- JPEG 2000 image coding system: Core coding system. The FGDC previously endorsed ISO/IEC 15444-1:2014. 

ISO/IEC 15444-1:2004 defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone gray-scale, palletized color, or continuous-tone color digital still images. It specifies decoding processes for converting compressed image data to reconstructed image data, a code stream syntax containing information for interpreting the compressed image data, and a file format. It provides guidance on encoding processes for converting source image data to compressed image data and implementing these processes.

Technical Corrigendum 1:2007 is a change notice for Annex I of ISO/IEC 15444-1:2004, while Technical Corrigendum 2:2008 provides clarification on determining maximum file size in Table A.46 of ISO/IEC 15444-1:2004. 

Technical Corrigenda 1:2007 and 2:2008 JPEG 2000 may be downloaded free of charge from webstore.ansi.org:

OGC GeoPackage 1.0 

OGC GeoPackage 1.0 defines GeoPackages for exchange and GeoPackage SQLite Extensions for direct use of vector geospatial features and/or tile matrix sets of earth images and raster maps at various scales. Direct use is the ability to access and update data in a "native" storage format without intermediate format translations in an environment (e.g. through an API) that guarantees data model and data set integrity and identical access and update results in response to identical requests from different client applications. GeoPackages are interoperable across all enterprise and personal computing environments and are particularly useful on mobile devices like cell phones and tablets in communications.

Geopolitical Entities, Names, and Codes (GENC) Standard Edition 2 

Geopolitical Entities, Names, and Codes (GENC) Standard, Edition 2.0, 31 March 2014 specifies an implementation of ISO 3166, Codes for the representation of names of countries and their subdivisions. Direct use of ISO 3166 conflicts with US Public Law 80-242 (1947), which requires the US Federal Government to use geographic names that have been approved by the US Board on Geographic Names (BGN). ISO 3166 contains country and subdivision names from the United Nations, which occasionally vary from those approved by the BGN. GENC Standard Edition 2.0 addresses U.S. Government requirements for restrictions in recognition of the national sovereignty of a country and identification and recognition of geopolitical entities not included in ISO 3166.   

The GENC Standard Ed. 2.0 comprise the U.S. Government implementations of ISO 3166-1, Codes for the representation of names of countries and their subdivisions – Part 1: Country codes, and ISO 3166-2, Codes for the representation of names of countries and their subdivisions -- Part 2: Country subdivision code.  

The FGDC previously endorsed GENC Standard 1.0.  GENC Standard 2.0 supersedes GENC Standard 1.0. GENC Standard 2.0 may be downloaded from https://nsgreg.nga.mil/doc/view?i=2379.  The National Geospatial-Intelligence Agency (NGA) hosts an online, dynamic information resource, the GENC Registry (http://nsgreg.nga.mil/genc), in which content is structured in accordance with the GENC Standard information model. The GENC Registry is the single authoritative source for geopolitical entities (and administrative subdivisions), names, and codes.   

GeoRSS-Simple and GeoRSS-GML 

GeoRSS is a standardized way to encode location in RSS and Atom feeds. It allows users to perform geographic searches on feeds, or to map information found in feeds.  GeoRSS makes it possible to search with all sorts of geographic criteria.  Its location content consists of geometries (including geographic points, lines, and polygons of interest) and related feature descriptions. GeoRSS feeds are designed to be consumed by geographic software such as map generators.  GeoRSS promotes interoperability and "upward compatibility" across encodings through a common information model.   

There are currently two encodings of GeoRSS: GeoRSS-Simple and GeoRSS-GML.  GeoRSS-Simple is a very lightweight format that developers and users can add to their existing feeds quickly and easily. It supports basic geometries (point, line, box, and polygon) and covers the typical use cases when encoding locations.  GeoRSS GML is a formal GML Application Profile that supports a greater range of features, notably coordinate reference systems other than WGS-84 latitude/longitude. 

There are no restrictions, limitations, or other constraints that affect promulgation, adoption and/or implementation of GeoRSS.  The specifications for GeoRSS-Simple and GeoRSS GML are freely available through www.georss.org.
