Abstract specification

The OGC Technical Committee (TC) has developed an architecture in support of its vision of geospatial technology and data interoperability called the OGC Abstract Specification. The Abstract Specification provides the conceptual foundation for most OGC specification development activities. Open interfaces and protocols are built and referenced against the Abstract Specification, thus enabling interoperability between different brands and different kinds of spatial processing systems. The Abstract Specification provides a reference model for the development of OGC Implementation Standards.

Topic 0 - Overview04-084r4George Percivall2020-08-27
This document (Topic 0) is an overview of the OGC Abstract Specification.
Topic 1 - Spatial schema17-087r13John R. Herring2020-08-28
This document is the ISO 19107:2019 Standard and specifies conceptual schemas for describing the spatial characteristics of geographic entities, and a set of spatial operations consistent with these schemas. It treats vector geometry and topology.

This document is consistent with the third edition (2019) of ISO 19111, Geographic Information - Referencing by coordinates includi...Click to continue reading
Topic 5 - Features08-126Cliff Kottman, Carl Reed2009-01-15
From ISO 19101, “A feature is an abstraction of a real world phenomenon”; it is a geographic feature if it is associated with a location relative to the Earth.
Topic 6 - Schema for coverage geometry and functions07-011OGC2007-12-28
This International Standard defines a conceptual schema for the spatial characteristics of coverages. Coverages support mapping f...Click to continue reading
