Why yet another OWS Server?

>Easier configuration

>Exactly the same look as QGIS Desktop

>Re-Use existing QGIS Desktop projects for publication on the Web and as OWS services

>Use the powerful symbology and labeling features of QGIS

>Reuse many settings from QGIS Desktop

>Web based printing out of the box

>Benefit from the dynamics of the QGIS desktop project


What is QGIS server?

>Standard compliant WMS server

>WMS extensions for QGIS web client

>WFS server

>Configuration in the QGIS project and layer settings


Technical Background

>Works with Apache server

>FastCGI application

>Uses the QGIS core libraries

>Configuration read from .qgs project files or alternatively from SLD

>Caching for project and layer settings

>Requires X-Server only for special symbology features


OWS Project Configuration - Metadata


Exclude layers and composers


Selectively publish attributes for WMS/WFS


Configure layers for WFS publication


Additional honored QGIS Desktop settings

Layer identifyabilityand display field


Available WMS Commands

>GetCapabilities

>GetMap

>GetFeatureInfo (with extensions)

>GetLegendGraphics (with extensions)

>GetProjectSettings (extended GetCapabilities)

>GetPrint (proprietary)

Future plans for QGIS Server

>Export Widget/Form information

>Cascaded GetFeatureInfo support

>Geodata shop functionality – download original data of user-defined extent

>Printing enhancements: print of redlining/annotation content, print custom overlay/base-map layers

>Exposes serial print / data sheet functionality for reporting


QGIS Web Client Motivation

Goal is to build a

>Easy to use and user friendly webgis client

>That tightly integrates with QGIS server

>Built on top of standard webgis components: OpenLayers, ExtJS, GeoExt

>Easy to configure and update


QGIS Web Client Features

>Map display with navigation

>Layer control with reordering and transparency

>Legend and metadata window

>Print tool using the QGIS desktop print layouts

>Attribute data display

>Theme choice

>Measure tools

>Search
