Features

• Raster and Vector Tile Renderers - Provides a high-performance GPU-accelerated engine for rendering both vector and raster map tiles on web pages.
• WebGL & GPU Rendering - Uses a high-performance WebGL rendering engine to draw vector tiles and 3D geometry directly on the GPU.
• Custom Data Source Integrations - Integrates diverse geographic data sources including vector tiles, GeoJSON, raster DEM, and video sources.
• 3D Map Renderers - Renders three-dimensional topography and elevation data to provide a realistic 3D map perspective.
• Interactive Map Viewers - Provides a high-performance interactive map viewer with GPU-accelerated vector tiles, panning, and zooming.
• Layer-Based Composition - Draws geographic data as organized layers of fills, lines, and symbols based on zoom levels.
• Geospatial Visualizations - Enables the visualization of complex geographic data using heatmaps, 3D extrusions, and dynamic vector styling.
• Geographic Visualization Tools - Serves as a web-based tool for creating complex GIS visualizations, including 3D terrain and heatmaps.
• Geographic Projections - Provides Mercator projection algorithms to translate geographic longitude and latitude into screen pixel coordinates.
• Data-Driven Styling - Assigns colors and visual properties to map features dynamically based on their underlying geospatial attributes.
• Map Style Managers - Provides systems for defining and managing the visual appearance of maps via external style configuration files.
• Map Style Specifications - Decouples visual map appearance from geographic data using a structured JSON specification for rendering properties.
• Geolocation and Mapping - Integrates user geolocation tracking to display and follow the user's current position on the map.
• Camera and Viewport - Manages the map viewport by interpolating between locations and adjusting pitch, bearing, and bounding boxes.
• Data Visualization - Provides specialized geospatial visualization tools including heatmaps, clusters, and 3D extrusions.
• External Model Integration - Supports the rendering of external 3D models and custom tiles via style layers and graphics libraries.
• Asynchronous Tile Loading - Utilizes web workers to fetch and parse map tiles in the background, preventing UI thread blockage.
• User Interaction - Captures pointer coordinates to identify map features under the cursor and enable draggable markers.
• Raster Map Integration - Supports the integration of third-party raster data including cloud-optimized geotiffs and web map services.
• Icon-Based Point Visualizers - Maps data categories to distinct visual icons and symbols for point-based geographic visualization.
• Location Services - Offers capabilities to geolocate users, track movement, and overlay interactive markers and popups on a map.
• Vector Interpolators - Implements vector interpolation logic to ensure smooth transitions for camera movements, pitch, and bearing.
• Feature Layer Filtering - Allows users to hide or show specific map symbols and layers based on property values or global state.
• Event Handling Systems - Implements an event system that triggers custom logic based on user interaction or map state updates.
• Event-Driven Interaction Handlers - Uses a centralized event dispatcher to translate raw input gestures into map-specific camera and interaction actions.
• Viewport Constraints - Restricts map panning and movement to specific geographic boundaries to keep the user within a designated area.
• Map Data Overlays - Enables the integration of markers, popups, and navigation controls as overlays on the map interface.
• Frontend Mapping Frameworks - Community-led fork of Mapbox GL JS for interactive maps.
• Mapping Libraries - Open-source fork of Mapbox GL for vector maps.
• Programming Libraries - GPU-accelerated vector tile renderer.
• Web Mapping Frameworks - Community-driven fork of Mapbox GL JS for vector maps.
