Description

english

With each Maprequest the Module UseMap starts a request to a WFS. The objects (just pointobjects for now) will be overlayed in the map and are mouse-sensitive.

[edit]

Installation

For drawing geometries the free Graphiclibrary (LGPL) wz_jsgraphics.js will be used. It will be included in a particular Mapbender-GUI as a separate Modul
The JavaScript-Functionality will be included in Mapbender with the Module 'usermap'. This Module will be included as an IFRAME and will also be used for data transfer between WFS and Mapbender. For editing data (gml) another script with the same name (see register 'php') is required. In this file the configuration of the WFS within this prototype is made.

How to configure the usemap-modul

Notice

There can only be one usemap-modul integrate in a gui. To enable more then one usemap-modul in a GUI a redisign of the modul would be necessary.

There are two files you have to adapt.

[edit]

/javascripts/mod_usemap.php

define the getFeature_Request

(line 21)var mod_usemap_wfs = "<url>";

mod_usemap_wfs has to sign on an valid getFeature-request. At the moment only point-objects are possible

For example:

var mod_usemap_wfs = "http://wms1.ccgis.de/cgi-bin/mapserv?map=/data/umn/mapbender_user/mapbender_user.map&Request=getFeature&Version=1.0.0&Service=WFS&typename=Mapbender_Names";

Link on tooltip

(line 49) str += " href='#'>";

Replace the # with a valid link. This link will be opened on click on the tooltip.

For example:

str += " href='http://mapbender.org/'>";

cw_bndcolor and cw_fillcolor

Set the color of the circle which will be drawn

[edit]

/php/mod_usemap.php

Decide which attributs to use for the tooltip-text:

(line 39) echo "um_title[um_title.length] ='".$g->getValueBySeparatedKey($ii,"name")."';";

Get the entries from the gml-tag you are interested in. Replace "name" with the desired tag-name.

For example:

echo "um_title[um_title.length] ='".$g->getValueBySeparatedKey($ii,"firstname")." ".$g->getValueBySeparatedKey($ii,"lastname")."';";

Das Module UseMap fordert mit jeder Kartenanfrage eine Anfrage an einen WFS mit an. Die Objekte (bisher nur Punktobjekte) werden in der Karte überlagert und reagieren auf Mausereignisse.

[edit]

Installation

Für das Zeichnen der Geometrien wird die freie (LGPL) Grafikbibliothek wz_jsgraphics.js verwendet. Diese wird als gesondertes Modul in die jeweilige Mapbender-Oberfläche eingebunden.
Die JavaScript-Funktionalität wird mit dem Modul 'usemap' in den Mapbender integriert. Dieses Modul wird als IFRAME eingebunden, das zudem für den Datentransfer zwischen WFS und Mapbender verwendet wird.

Für die Aufbereitung der Daten (GML) wird noch ein weiteres gleichnamiges Skript (im Verzeichnis 'php') benötigt. In dieser Datei wird in diesem Prototyp auch die Konfiguration des WFS vorgenommen!
