Data Standards - Open GIS Consortium
About the Open GIS Consortium (OGC)
When searching the Internet and off-line archives,
users realize how much geospatial data is available. This data is
varied and often times incompatible. In order to combine the data
in a GIS system as different layers, the user must manipulate the
data. This data manipulation can be difficult as well as time-consuming
and may lead to errors. In order to properly over-lay that data,
there must be a common interface. In 1994, the Open GIS Consortium
was developed in the United States and now has over 150 members
in twenty-six countries. The OGC defines OpenGIS as "transparent
access to heterogeneous geodata and geoprocessing resources in a
networked environment. The goal of the OGC is to provide open interface
specifications that enable developers to write interoperating components
that provide these capabilities". (www.opengis.org) In other words,
geospatial data will be located in a central area on the Internet
and will be compatible. It's goal is to benefit the user.
The OGC’s mission is to promote the development
and use of advanced open systems standards and techniques in the
area of geoprocessing and related information technologies.
The OGC states the advantages of the developing standards
as follows:
- "Geospatial information should be easy
to find, without regard to its physical location.
- Once found, geospatial information should
be easy to access or acquire.
- Geospatial information from different sources
should be easy to integrate, combine, or use in spatial analyses,
even when sources contain dissimilar types of data (raster, vector,
coverage, etc.) or data with disparate feature-name schemas.
- Geospatial information from different sources
should be easy to register, superimpose, and render for display.
- Special displays and visualizations, for
specific audiences and purposes, should be easy to generate, even
when many sources and types of data are involved.
- It should be easy, without expensive integration
efforts, to incorporate into enterprise information, systems geoprocessing
resources from many software and content providers."
