• Spatial data types and geometry operations in PostGIS.
• Visualizing spatial data from PostGIS in web-based maps.

Creating Interactive Maps with Leaflet:

• Introduction to Leaflet.js for lightweight and flexible web maps.
• Adding layers, markers, pop-ups, and tooltips to maps.
• Styling and customizing maps using Leaflet plugins and extensions.
• Building a simple interactive map with Leaflet.

Advanced Web Map Development with OpenLayers:

• Overview of OpenLayers for creating advanced web GIS applications.
• Working with vector and raster layers in OpenLayers.
