.. _demos: Demos ===== This page contains helpful links to various information pages regarding GeoServer and its features. You do not need to be logged into GeoServer to access this page. The page contains the following options * :ref:`demos_demorequests` * :ref:`srs_list` * :ref:`demos_reprojectionconsole` * :ref:`demos_wcsrequestbuilder` .. figure:: img/demos_view.png Demos page If you have the :ref:`WPS ` extension installed, you will see an additional option: * :ref:`demos_wpsrequestbuilder` .. figure:: img/demos_viewwps.png Demos page with WPS extension installed .. _demos_demorequests: Demo Requests ------------- This page has example WMS, WCS, and WFS requests for GeoServer that you can use, examine, and change. Select a request from the drop down list. .. figure:: img/demos_requests.png Selecting demo requests Both :ref:`wfs` as well as :ref:`wcs` requests will display the request URL and the XML body. :ref:`wms` requests will only display the request URL. .. figure:: img/demos_requests_WFS.png WFS 1.1 DescribeFeatureType sample request (Demo Request :guilabel:`WFS_describeFeatureType-1.1.xml`) Click :guilabel:`Show Result` or :guilabel:`Show Result in New Page` to send the request to GeoServer. For WFS and WCS requests, GeoServer will automatically generate an XML response. :guilabel:`Show Result` will show GeoServer's response - both the response headers and the XML/image result - below the :guilabel:`Show Result` button. If GeoServer's response is XML and you have ticked :guilabel:`Pretty Print XML`, GeoServer's response will be shown with an easy to read styled formatting. :guilabel:`Show Result in New Page` will show GeoServer's result in a new page (your browser will render the result). .. figure:: img/demos_requests_schema.png Headers and XML response from a WFS 1.1 DescribeFeatureType sample request after pressing :guilabel:`Show Result`. (Demo Request :guilabel:`WFS_describeFeatureType-1.1.xml`) Submitting a WMS GetMap request displays an image based on the provided geographic data. .. figure:: img/demos_requests_WMS_map.png Headers and image response for a WMS GetMap request after pressing :guilabel:`Show Result`. (Demo Request :guilabel:`WMS_getMap_multilayer.url`) WMS GetFeatureInfo requests retrieve information regarding a particular feature on the map image. .. figure:: img/demos_requests_WMS_feature.png Plain text WMS GetFeatureInfo request after pressing :guilabel:`Show Result`. (Demo Request :guilabel:`WMS_featureInfo.url`) .. figure:: img/demos_requests_transaction.png WFS Transaction result after pressing :guilabel:`Show Result in New Page` (Your browser may render this differently). (Demo Request :guilabel:`WFS_transactionInsert.xml`) .. _srs_list: SRS List -------- GeoServer natively supports almost 4,000 Spatial Referencing Systems (SRS), also known as **projections**, and more can be added. A spatial reference system defines an ellipsoid, a datum using that ellipsoid, and either a geocentric, geographic or projection coordinate system. This page lists all SRS info known to GeoServer. .. figure:: img/demos_SRS.png Listing of all Spatial Referencing Systems (SRS) known to GeoServer The :guilabel:`Code` column refers to the unique integer identifier defined by the author of that spatial reference system. Each code is linked to a more detailed description page, accessed by clicking on that code. .. figure:: img/demos_SRS_page.png Details for SRS EPSG:2000 The title of each SRS is composed of the author name and the unique integer identifier (code) defined by the Author. In the above example, the author is the `European Petroleum Survey Group `_ (EPSG) and the Code is 2000. The fields are as follows: :guilabel:`Description`—A short text description of the SRS :guilabel:`WKT`—A string describing the SRS. WKT stands for "Well Known Text" :guilabel:`Area of Validity`—The bounding box for the SRS .. _demos_reprojectionconsole: Reprojection console -------------------- The reprojection console allows you to calculate and test coordinate transformation. You can input a single coordinate or WKT geometry, and transform it from one CRS to another. For example, you can use the reprojection console to transform a bounding box (as a WKT polygon or line) between different CRSs. .. figure:: img/demos_reprojectionconsole.png Reprojection console showing a transformed bounding box Use :guilabel:`Forward transformation` to convert from source CRS to target CRS, and :guilabel:`Backward transformation` to convert from target CRS to source CRS. You can also view the underlying calculation GeoServer is using to perform the transformation. .. figure:: img/demos_reprojectionconsoledetails.png Reprojection console showing operation details Read more about :ref:`crs_handling`. .. _demos_wcsrequestbuilder: WCS Request Builder ------------------- The WCS Request Builder is a tool for generating and executing WCS requests. Since WCS requests can be cumbersome to author, this tool can make working with WCS much easier. Read more about the :ref:`wcs_request_builder`. .. _demos_wpsrequestbuilder: WPS Request Builder ------------------- GeoServer with the :ref:`WPS extension installed ` includes a request builder for generating and executing WPS processes. Since WPS requests can be cumbersome to author, this tool can make working with WPS much easier. Read more about the :ref:`wps_request_builder`.
