Learn how to create and customize layers to organize your geographic data effectively.
Layer Types
Spatly supports four primary layer types:
- Point layers — Individual locations like markers, POIs, sensors
- Line layers — Roads, rivers, routes, paths
- Polygon layers — Areas, boundaries, zones, buildings
- Heatmap layers — Density visualization from point data
Styling Options
Every layer has a visual style you can customize:
- Fill Color — The interior color of polygons and points
- Stroke Color — The border/outline color
- Stroke Width — Border thickness in pixels
- Opacity — Transparency from 0 (invisible) to 1 (opaque)
- Point Radius — Size of point markers
Data-Driven Styling
Use style rules to vary the appearance of features based on their attributes. For example, color zones by population density or size markers by revenue.
Layer Organization
- Drag layers to reorder them — layers higher in the list render on top
- Use the visibility toggle to temporarily hide layers
- Group related layers by naming them with a common prefix
