Redesign of OGC Symbology Encoding standard for sharing cartography

Despite most Spatial Data Infrastructures are offering service-based visualization of geospatial data, requirements are often at a very basic level leading to poor quality of maps. This is a general observation for any geospatial architecture as soon as open standards as those of the Open Geospatial Consortium (OGC) have to be applied. To improve this situation, this paper does focus on improvements at the (inter)operability side by considering standardization aspects. We propose two major redesign recommendations. First to consolidate the cartographic design knowledge at the core of the OGC Symbology Encoding standard. Secondly to build the standard in a modular way so as to be ready to host upcoming cartographic requirements. Thus, we start by defining the main portrayal interoperability use cases that frame the concept of sharing cartography. Then we bring to light the strengths and limits of the relevant open standards to consider in this context. Finally we paint a set of recommendations to overcome the limits so as to make these use cases a reality. Even if the definition of a cartographic-oriented standard is not able to act as a complete cartographic design framework by itself, we argue that pushing forward the standardization work dedicated to cartography is a way to share and disseminate good practices and finally to improve the quality of the visualizations.
