Towards a standard for interoperable earth system raster services
Baumann, Peter
Online services for multi-Terabyte satellite imagery are becoming integral part of Internet users' life. The general concept of multi-dimensional spatio-temporal raster data covers 1-D sensor time series, 2-D imagery, 3-D image time series and exploration data, 4-D climate models, and many more. Standards for interoperable geo services are mainly developed by the Open GeoSpatial Consortium (OGC). Among them is the Web Coverage Service (WCS) which allows to retrieve all or part of a coverage (i.e., raster) object. Recently an initiative has started on a Web Coverage Processing Service (WCPS) allowing, based on the conceptual model of WCS, to submit QL-style requests for online data navigation and analysis in a set-oriented coverageexpression language. WCPS currently is an OGC approved Best Practices Paper. A reference implementation is under work. This paper presents WCPS concepts with the intent of involving the research community at an early standardization stage to gain feedback and comments, and also to stipulate research in this area.
