Presentation to for the ISPRS Congress 2012, Melbourne

Over the last decade, standards have played a key role in the expansion of the market for Earth Observation (EO) products and services. Standards become increasingly important as geospatial technologies and markets continue to evolve in an increasingly complex technology ecosystem. OGC and ISPRS work jointly to further the development of this vital information industry.

We continue to see global growth in the supply of geometrically controlled image-based geodata. On the data supplier side, most end-use EO information products use data from multiple EO sources (aerial and satellite) as well as from ground-based sources. On the customer side, customers’ business models involving EO data require easy connections between multiple data suppliers and multiple technology platforms. Typically, new markets create stovepiped, proprietary solutions that persist until market forces create demand for standards that in turn enhance market opportunity. The OGC’s standards meet this demand in the geospatial markets.

OGC leads worldwide in the creation and establishment of standards that allow geospatial content and services to be seamlessly integrated into business and civic processes, the spatial web and enterprise computing. OGC accelerates market assimilation of interoperability research through collaborative consortium processes.
OGC has both domain focused and technology focused activities. For example, the Meteorology & Oceanography Domain Working Group ensures that OGC standards and profiles allow the meteorological community to develop effective interoperability for web services and content across the wider geospatial domain. These needs are met for example by the technology of standards such as netCDF which was brought into the OGC to encourage broader international use and greater interoperability among clients and servers interchanging data in binary form.

Most OGC standards specify open interfaces or encodings that apply to imagery. Some of these are:
o Web Coverage Service (WCS)
o Web Coverage Processing Service (WCPS)
o Web Map Service (WMS)
o Geography Markup Language (GML)
o GML in JPEG 2000 Encoding
o OGC Network Common Data Form (NetCDF)
o Sensor Observation Service (SOS)
o Sensor Planning Service (SPS)
o Sensor Model Language Encoding Standard (SensorML).
o Catalogue Service for the WEB (CSW)

User Perspective • Rapidly mobilize new capabilities • Lower system lifecycle costs • Encourage market competition • Choose solutions based on functionality desired • Avoid “lock in” to a proprietary architecture • Decision to share information and services becomes a • decision “What OGC brings to the table is…everyone has confidence we won’t take advantage of the format or change it in a way that will harm anyone” Michael Weiss-Malik, Google KML product manager © 2012, Open Geospatial Consortium
    19. 19. Making Location Count... DigitalGlobe on Standards and OGC “Standards-based interoperability is key for improved timeliness for delivering relevant imagery to our users. It just works.” “These well defined standards enable quick integration into existing and custom workflows and allow mashups with many types of other OGC- delivered geospatial content. “We deliver FirstLook imagery to the UN entirely via OGC-based services (e.g. WMS, WMTS, WFS, KML) “In addition to providing imagery to end users, we also work with partners and other vendors to extend valuable geospatial content into their products using OGC services…” John Lucier, Senior Manager, DigitalGlobe
