GML 3.1.1 Application schema for Earth Observation products

This OGC Best Practice application schema document describes the encodings required to describe Earth Observation (EO) products from general to mission specific characteristics.

This document specifies three compliance levels :

1. - The general level, or "hma" level, describes the general EO Products schema;

 

2. - The thematic level extends the "hma" level to describes thematic EO Products such as optical, radar or atmospheric products (respectively "ohr", "sar", "atm" levels);

 

3. - The mission specific level extends one of the "thematic" level to describes mission specific EO Products. For instance the French Pleiades mission uses the "phr" level which extends the "ohr" thematic level.
