Abstract
This paper describes a Cartographic Dashboard for Statistical Data in the Dutch Spatial Data Infrastructure. That is, a system that can consume a combination of data services from the SDI, and cartographically integrate them, so that visual comparison of data from different providers or different data from a single provider is optimized. The Carto Dashboard can be considered as a smart data viewer that “Thinks like an Atlas”. In order to realize the Carto Dashboard with atlas–quality output, a conceptual change was needed in the way the mapping from the SDI is arranged. To achieve more control over the mapping process, we consume data services (using GeoJSON) instead of portrayal services. Furthermore, we used our existing Atlas Map Viewer component, a web application using HTML5 technology and the D3 javascript library. We further built on this web application by having it connect to the Statistics Netherlands (CBS) Open Data API, which is using the ODATA standard. We added functionality specifically for Statistical Data visualisation, concentrating on comparison tools. With created possibilities for: - comparisons in space (using the same variable in different places or the same variable with different aggregation) - comparisons in time (using the same variable for different times) - and comparisons between themes (same place and time, different variables).
