Prepare a QGIS project for Web

Create your project

Add your data:

  • Vector geographic data files
    • ESRI Shapefile
    • MapInfo TAB and MIF/MID
    • GeoJSON
    • etc
  • RASTER geographic data files
    • GeoTIFF
    • Arc/Info ASCII Grid
    • netCDF
    • etc
  • Geographic data base
    • PostgreSQL / PostGIS
    • MSSQL spatial
    • 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.

Note

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
    • etc
  • 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 menu Project ‣ Project Properties or 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
