Learn to interact with vector layer features in OpenLayers, showing a popup with GeoJSON properties for points, lines, and polygons via a click-driven overlay.

Learn how to implement interactions for vector layer features in OpenLayers, switch to pointer move for hover popups, and filter layers so only geojson features respond.

Explore basic OpenLayers styling for polygons, lines, and points using the Style class, applying fill, stroke, and dash options, with z-index priorities to manage layered vector features.

Explore styling points in OpenLayers by using dot style options, including circle and regular shapes, with customizable fill, stroke, radius, and rotation to create triangles, stars, and circles.

Apply styles to points, lines, and polygons based on feature properties in OpenLayers, building a choropleth map by income and grouping data by attributes.

Learn to style openlayers 6 features based on properties, displaying feature IDs as text on polygons using a text style and set style.

Compare epsg 3857 (spherical mercator) with epsg 4326 in OpenLayers, showing how projection choice changes coordinates to longitude and latitude, affects distortion, and how to view a graticule on click.

Learn to set and register custom epsg projections in OpenLayers 6, using Proj4js to handle epsg codes like Austria’s, and translate data to the view projection.

Transform coordinates between projections in OpenLayers by converting longitude and latitude from WGS 84 (EPSG 4326) to EPSG 3416, and transform extents to center Vienna.

OpenLayers automatically reprojects data sources into the view projection when needed by specifying the data source projection, enabling conversion to the British National Grid EPSG 27700.

Learn to implement the select interaction in OpenLayers to select vector features, style selected points, and restrict interaction to chosen layers.

Learn to add and customize a select interaction in OpenLayers 6, handle select events, access selected features and their geometry types, and style points, polygons, and linestrings on the map.

Style and customize OpenLayers map controls with CSS, adjusting zoom, attribution, and rotate buttons, plus adding scale line and overview map to suit your UI.

Learn to manipulate OpenLayers map controls with four toggle buttons (zoom, attribution, overview map, scale line) that switch controls on and off and update button styles.

Use the geolocation API in OpenLayers to identify the user's location, track movement, and center the map view on longitude and latitude—displaying coordinates in EPSG 3857.

Create a front-end tour map of Australian capital cities with open layers, using a local geojson file to click, hover, and highlight features while updating a responsive UI.

Set up an OpenLayers project environment by creating folders, adding index.html, main.js, and styles.css, and integrating the OpenLayers library with an OpenStreetMap layer centered on Australia.

Prepare project data by creating a geojson of Australian capital cities with coordinates and a city image, then define id, city name, and ct image columns and save as geojson.

Create a three-column user interface with a font awesome icon navigation, render an OpenLayers map, and display a city info panel with a flag image.

Learn to add Australian capital cities from a geojson file to an Openlayers map as a vector layer, and style the features as circle markers with IDs displayed.
