Preface This document explains how the Web Map Server specification can be extended to allow user-defined symbolization of feature and coverage data. It should be read in conjunction with the latest version WMS specification. The WMS 1.3 Specification, OGC 06-042, is the most recent OGC member approved version of that specification. This document is together with the Symbology Encoding Implementation Specification the direct follow-up of Styled Layer Descriptor Implementation Specification 1.0.0. The old specification document was split up into two documents to allow the parts that are not specific to WMS to be reused by other service specifications. ii. Document terms and definitions This document uses the specification terms defined in Subclause 5.3 of [OGC 05-008], which is based on the ISO/IEC Directives, Part 2. Rules for the structure and drafting of International Standards. In particular, the word “shall” (not “must”) is the verb form used to indicate a requirement to be strictly followed to conform to this specification iii.

To enable this, we need homogenous data as well as proper integration methods. Geospatial data integration has been a long- standing research topic for decades, and this paper discusses the utilisation of Linked Data technology stack to alleviate the geospatial data integration, particularly in the multi-scale context. Furthermore, this paper also discusses the possibilities of incorporating symbolisation information in Linked Data along with the integrated linked geospatial data for visualisation.

  • Wms) with Styled Layer Descriptor (Sld) for Creating Dynamic and User-Oriented Maps
    CO-434 USING WEB MAP SERVICE (WMS) WITH STYLED LAYER DESCRIPTOR (SLD) FOR CREATING DYNAMIC AND USER-ORIENTED MAPS BURDZIEJ J. Nicolaus Copernicus University, TORUN, POLAND BACKGROUND AND OBJECTIVES Recent years has shown the increased use of Web Map Services (WMS) for publishing maps in the web environment. The basic idea behind WMS standard is to provide a simple web interface for requesting georeferenced map images (OGC, 2010). Each WMS request defines map layers to be processed and geographic boundaries for which the map will be rendered. Web Map Service, as opposed to the Web Feature Service (WFS), serves raster map images instead of raw vector data in order to enhance web map performance. Maps exposed as WMS services can be symbolized using the Styled Layer Descriptor (SLD), an XML- based markup language, which enables to create advanced rules for cartographic visualization of geospatial data. SLD schema can be used for symbolizing point, line, polygon as well as raster layers, for labeling features and creating scale dependent styles. It can also be used with filters in order to define custom classes and categories for creating thematic maps. These two open standards, officially released by the Open Geospatial Consortium (OGC), are nowadays defining the foundations for modern web mapping. Many different kinds of Internet maps act as WMS clients, displaying thematic WMS layers. Also a growing number of desktop applications, both open source and proprietary, can now connect to WMS servers and display WMS layers along with other geospatial data, such as vector objects or raster images stored locally on desktop computers.
