5.4 Raster Properties 5.4.5. Histogram Tab The histogram tab allows you to visualize the histogram of your rasterdata. This is useful to get an idea about the pixel-distribution. Two different chart types are allowed: Barcharts and Linegraphs. QGIS 0.8 User Guide 41
6. Working with OGC Data 6.1. What is OGC Data The Open Geospatial Consortium (OGC), is an international organization with more than 300 commercial, governmental, nonprofit and research organisations worldwide. Its members develop and implement standards for geospatial content and services, GIS data processing and exchange. Describing a basic data model for geographic features an increasing number of specifications are developed to serve specific needs for interoperable location and geospatial technology, including GIS. Further information can be found underhttp://www.opengeospatial.org/. Important OGC specifications are: • WMS - Web Map Service • WFS - Web Feature Service • WCS - Web Coverage Service • CAT - Web Catalog Service • SFS - Simple Features for SQL • GML - Geography Markup Language OGC services are increasingly being used to exchange geospatial data between different GIS implementations and data stores. QGIS can now deal with two of the above specifications, being SFS (though support of the PostgreSQL / PostGIS data provider, see Section 4.2); and WMS as a client. 6.2. WMS Client New in v0.8 6.2.1. Overview of WMS Support QGIS currently can act as a WMS client that understands WMS 1.1, 1.1.1 and 1.3 servers. It has particularly been tested against publicly accessible servers such as DEMIS and JPL OnEarth. WMS servers act upon requests by the client (e.g. QGIS) for a raster map with a given extent, set of layers, symbolisation style, and transparency. The WMS server then consults its local data sources, QGIS 0.8 User Guide 42
