A Web server for accessing a database on solar radiation parameters

Résumé

Ecole des Mines de Paris has gathered since many years a lot of Earth Observation data of different kinds and is willing to provide those data to a broad audience. In collaboration with European partners, Ecole des Mines de Paris has assembled a dataset, which is unique in the world. It deals with one parameter of the solar radiation: the Linke turbidity factor, which characterizes the opacity of the atmosphere. Recently, the advent of the World Wide Web (WWW), has laid the foundation of a simple, friendly and uniform way of sharing data on internet. Nevertheless, the complexity and the size of some dataset and the heterogeneity of files formats were not suited to be put on-line on the web without preparation. The need of being able to make sophisticated queries to extract relevant information has therefore lead us to build a database (SQL) / Web server. The HELIOSERVEserver has been opened in late November 1997. Several customers have already praised its usefulness. This paper explains the design of the web server call HELIOSERVE. It describes the scientific context and explains the different steps to transform a dataset into a database that can be queried via the WWW. The authors have also examined a more general problem : the construction of a web server by small university-like entities which want to promote their database in Earth Observation related domains. Some conclusions were reached and are presented. Guidelines on how to help these small size providers are discussed.
