Introduction to Open Source Web GIS Programming

Learn to add a leaflet tilelayer by initializing a map, configuring view coordinates, and linking an OpenStreetMap tile source to render the basemap in a web GIS app.

Learn to implement a layer controller in a web GIS app, manage multiple map layers and markers, and group layers for streamlined control using leaflet.

Install PostgreSQL by downloading the latest 11.2 installer and creating a spatial database. Explore coordinate systems and spatial features as you set up the environment.

Learn to customize the Django admin interface with the Leaflet library to visualize and edit geographic data on a map, including polygons, populations, and regional attributes.

Fix auto-generated django model content in a web geographic information system app by editing admin-loaded data, resolving decimal and digit validation errors, and updating geometry and related fields.

Introduce an open source geospatial server that publishes data from various sources using open standards, offers web map services and other outputs, and works with mapping libraries like Leaflet.

Navigate the Geoserver GUI to create a workspace, publish layers, and view WMS and WFS services, while configuring authentication, memory settings, and basic server administration.

Upload datasets to the server, create a new data store, and publish layers for visualization in leaflet by configuring data sources and bounding boxes.

update a layer's default style in a web GIS project by classifying data, renaming labels, applying colors, and saving and publishing styled layers for map use.

Implement a WMS with Django and Leaflet using GeoServer, configure static files and templates, and load multiple map layers with attribute-based filtering for vector data.

Add a legend to map layers by linking styles, loading legends from the style and layer configuration, and testing with publishing settings.

Configure a WMS image request in a leaflet-geoserver setup by mapping three layers with filters and parameters to zoom to specific areas and display district borders.
