The OpenGIS Abstract +Specification defines a simple Surface as consisting of a single 'patch' +that is associated with one 'exterior boundary' and 0 or more 'interior' +boundaries.
For example, in different coordinate systems distance +between two objects may differ even objects have the same coordinates, +like distance on plane coordinate system and distance on geocentric +(coordinates on Earth surface) systems are different things.

This table is defined by the OpenGIS SQL specification, and may be updated by other applications, with geometry columns not managed by ArcSDE.
The actual representation of the geometry and storage of the coordinate data is DBMS specific and never exposed to the application.
Functions prefixed with SE_ are not part of the SQL/MM or OpenGIS specifications, but have been added to ArcSDE implementations on IBM DB2 and Informix to support extended functionality.

 OGIS RFI3 Response from FGDC   (Site not responding. Last check: 2007-11-01)
It is suggested that the OpenGIS RFP include specifications for the trans-community "publishing" of catalog services as geospatial data is rarely limited in its use to only one information community.
This list is presented as an interim form for the user to evaluate and may include a small set of elements to include title, geographic and temporal extent values, and other basic information that could be used in visualization of the references before direct access is made.
With respect to the role of different levels of metadata in a catalog service, we have noted that there is a potential inheritance model of metadata that can be applied in order to maximize the sharing of metadata element values among different granularities of information.

 Cover Pages: Geography Markup Language (GML)
The OpenGIS Abstract Specification defines a geographic feature as: '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." Thus a digital representation of the real world can be thought of as a set of features.
By 'information encoding and service request using XML' we mean an XML compliant set of rules for the creation, population, query and response to query for the interoperable handling of feature operations, attributes, geometry, and geometry collections.
One goal is transparent integration of data from earth imaging platforms and ground collection systems (for water quality, GPS correction stations, dynamic attribution sensors on lakes and dams, etc.)...OGC is an international industry consortium of over 200 companies, government agencies and universities participating in a consensus process to develop publicly available geoprocessing specifications.

The fact that a flagpole is not simple is one of the limitations of 2.5D, whereas in a 3D system the flagpole could be considered simple.
The OpenGIS Simple Features specification defines various spatial operators, which can be used to generate new geometries from existing geometries.
Then H is a subsystem of G, and H is isomorphic to SF, preserving the spatial relationship functions and the spatial operator functions.

 Demis WMS 4.0 Documentation
The OpenGIS Consortium, Inc. (OGC) is a member-driven, non-profit international trade association that lead the development of geo-processing interoperability computing standards.
When you visit the OpenGIS web site you may be overwhelmed by all the information there, the consortium has been working on various open standards, the Web Map Server (WMS) specification fortunately is the simplest one.
Please note that the OpenGIS Consortium (OGC) has changed it's name to Open Geospatial Consortium, but on our web site we still use the term OpenGIS as we find the name change may be a bit confusing, we will change the terminology at some point as the new name becomes fully established.

 GEO World - Feb 2004 - Look for the OpenGIS Certification Mark   (Site not responding. Last check: 2007-11-01)
If a software product includes an interface (or if a data product is based on an encoding) that implements a specific OpenGIS Specification, but the product hasn't passed a compliance test (perhaps because no test is yet available), the product's vendor can label the product as "implementing" a specific OpenGIS Specification.
The following "OpenGIS Compliant" certification mark is to be used only with products that have been tested and approved by OGC as "compliant" to one or more OpenGIS Implementation Specifications.
For products that are compliant to one or more OpenGIS Implementation Specification, the appropriate specification logo or full-text description of the specification should be used with the Certification Mark.

 Web Feature Service Implementation Specification   (Site not responding. Last check: 2007-11-01)
OpenGIS® is a trademark or registered trademark of Open GIS Consortium, Inc. in the United States and in other countries.
The datastore used to store geographic features should be opaque to client applications and their only view of the data should be through the WFS interface.
That is to say, when a WFS implementation reports a feature identifier for a feature instance, that feature identifier is unique to the server and can be used to repeatedly reference the same feature instance (assuming it has not been deleted).

 The Development of Spatial Information Distribution Component Model based on OpenGIS
The spatial information should be constructed without interference of any types of GIS engine and spatial DBMS to utilize the spatial information, but a duplicated investment in using spatial information since the current situation are not yet fully developed.
Especially, OpenGIS presented by OGC, for example, has Abstract Specification which is based on object oriented technology for the interoperability in the heterogeneous distributed computing environment and Implementation Specification for some related platform such as CORBA and OLE/COM and they are provided to software developers in the form of shared standard interface.
In the paper, we present a spatial information distribution component model based on OpenGis by using platform independent component technology for a solution of the sharing and integration of spatial information problem in a distributed computing environment and the reusability of software.

 The OpenGIS types in Magma/Lava   (Site not responding. Last check: 2007-11-01)
These four LavaShape’s behave exactly as there old counterparts, apart from the fact that their geometric parameter (as specified in the Lava configuration file) should have as type one of the corresponding four new Lava types.
In Lava the Lava type names are mapped to one of the four storage types, which are then passed with setValue to the appropriate LavaShape (note that this allows you to pass the OpenGIS type LineString to the MultiPointLavaShape, and the OpenGIS type Polygon to the MultiLineStringLavaShape).
In Magma the OpenGIS types are used to determine the output of Magma (and it is an error if the type name in ‘magmatypes’ does not correspond exactly to the type of the column).
