The charter is the formal document that specifies the working group’s objectives. It describes the mission and which results that are be delivered. In this blog, I want to address these objectives. The SDWWG is committed to improving and clarifying standards for dealing with spatial data on the web. And that’s badly needed, because the standards that are currently available are rather unclear. In some areas there are too many standards, for example about how a vector geometry (an ordered set of coordinates) can be coded, while in other areas there is a shortage of standardization. How to reference a coordinate system, for example, is not clear. This chaos can partly be explained by the ubiquity of spatial data. The vast majority of data that we want to use on the web has spatial aspects, which means that everyone who wants to do something with data should also do something with that spatial aspect. Many have already dealt with standardization of spatial data from the perspective of their own domain and, in some cases, they may even have done so before the web came into the picture as a platform for the exchange of data.
The OGC for geo-information experts , for example, has an extensive set of standards, which together form a complex, closed semantic system. In other domains, standards have also been developed for location, for example to express a toponym, an address, or a point location. The web, however, is an environment where all domains can come together.
