Soil Map Internet Service (SOMIS) is a web-based application for the navigation of soil related maps. This map service allows the user to navigate the European Soil Database and interact with map operations. The user can execute on-line almost all the mapping operations: Zoom in, Zoom out, Full Extent, Previous Extent, Panning, Panning to 4 directions, Query data, Identify, Select Features by Line/Polygon, Advanced Printing capabilities. Also it is possible to combine layers of maps located in different Map servers all around the World (According to INSPIRE principles). The Soil Portal is developed based on International standards and specifications, as laid down in the INSPIRE Guidelines, in order to attain the interoperability of data and services in support of the architecture. The Soil Portal has been configured according to those standards and can serve also as a Web Map Service (WMS), which produces maps of geo-referenced data, and in this service a "map" is defined as a visual representation of geodata or a geodatabase.
