Prepare a QGIS project for Web
Create your project
Add your data:
Vector geographic data files
MapInfo TAB and MIF/MID
RASTER geographic data files
Arc/Info ASCII Grid
Geographic data base
PostgreSQL / PostGIS
Oracle locator / spatial
Organize and manipulate the layes in the legend:
Add groups with a right click in the empty part of the legend: Add a new group
Move layers and groups with drag-and-drop
Rename layers and groups with the F2 key or the layer properties window
Manipulate the rendering order:
with the legend layer order: the upper layers are rendered above the others.
by specifying layer order with the menu View > Panels > Layer order
Add a title to your project and save it in your working directory.
New in Lizmap 3: if your layer has more than one style, the user will be able to switch between them through the button Change layer style at the top of the legend.
Set up your project for Web
Configure the coordinates reference system, CRS, of your project:
Select the CRS of your Web map:
EPSG:3857 for Google Mercator
EPSG:2154 for Lambert 93
Enable on the fly CRS transformation. QGIS can reproject raster and vector data.
Configure the Web Geographics Services parameters with the OWS Server tab:
Set the title of your Web Geographics Services
Add informations like your organization, the owner of the publication, the abstract, etc
Set the maximum extent of your WMS service
Restrict the CRSs list of your WMS service:
at least select the one used in your project
you can use the button Used to get all the layer CRS and the project one
Exclude compositions and layers if data cannot be published in WMS
Enable the layers you want to publish WFS and WCS
Check that the paths are saved relative in the general tab of the project properties window, access it with the menuor CTRL+SHIFT+P.
Configure your layers for the Web
In the window Layer properties, the Metadata tab allows you to configure a lot of information for Web Geographic Services:
Provide a title, a description and keywords
Specify the attribution to respect the data license
Add the metadata record URL if it’s available
