1.2. Open Geospatial Consortium (OGC)
Learning Objectives
You will be able...
- ...to define what OGC stands for and what their main activities are.
- ...to explain the difference between OGC's Abstract Specifications and Implementation Specifications.
- ...to chart the steps of an OGC process.
- ...to explain why you should use GML.
Introduction
|
As you aready learned in the previous unit, OGC developed publicly available specifications (at no cost) that support interoperable solutions that "geo-enable" the Web. These specifications empower developers to make spatial information and services accessible and useful with all kinds of applications. When they are implemented by two different software engineers working independently, the resulting components work together without further debugging. (OGC) |

This unit introduces OGC in more details. Their vision, mission, goals, and
activities are listed and the specifications that are important
for Web Mapping issues are presented as well.
Since the Geography
Markup Language (GML) is the basis for the standards "Web Map Service
(WMS)" and "Web Feature Service (WFS)" that will be
introduced in further chapters, we shortly explain you what GML was defined for
and
why you should use it.
