Styling layers

The Style panel on the right edits the appearance of the layer selected in the Layers panel. Vector and raster layers each have their own styling controls.

Vector styling

Vector layer styling covers these properties:

• Fill: color and opacity for polygon interiors.
• Stroke: line color and width for lines and polygon edges.
• Points: circle radius for point-based layers.
• Labels: text color, size, halo color and halo width.
• 3D extrusion: turn polygons into extruded blocks, with height field, scale, base height and color options.

Per-style minimum and maximum zoom settings restrict a style to a specific zoom range.

Point renderer (heatmap and clustering)

For point-only layers, the Point renderer control offers three options:

Renderer	What it does
Single symbol	One circle per point (default).
Heatmap	A density surface colored cold to hot; adjust radius and intensity.
Clustered	Groups nearby points into labeled bubbles; zoom in to expand.

Style type (data-driven styling)

The Style type control maps feature values to visual properties:

Style type	Purpose
Single symbology	A uniform style for every feature.
Graduated	Classify a numeric field into color-coded classes.
Categorized	Assign a color per unique category value.
Expression	Custom MapLibre expressions for advanced control.

Choropleth maps: choose Graduated, pick a numeric attribute, choose a colormap, then apply.

Raster styling

Raster layers can be adjusted with:

• Brightness (minimum and maximum)
• Saturation
• Contrast
• Hue rotation (in degrees)

These change the appearance of GeoTIFF, COG and tile-based rasters without altering the underlying data.

Legends and colorbars

To display a legend or a continuous colorbar on the map, open them from the Controls menu. They automatically reflect the current styling settings.
