• Heatmap Visualization - Generates heatmap overlays based on weighted coordinate points using customizable color gradients.
• GeoJSON Renderers - Includes an engine for rendering geographic features based on the GeoJSON specification.
• Interactive GeoJSON Layers - Renders custom GeoJSON data as styled, interactive layers with support for fill, outline, and hover events.
• Geographic Data Mapping - Provides tools for rendering spatial data and heatmaps to visualize the distribution of geographic points.
• Geospatial Data Import Tools - Provides utilities for importing geographic entities from standardized KML and GeoJSON files.
• KML and GeoRSS Importers - Provides a specialized importer for loading KML geospatial data into map overlays.
• Spatial Geometry Calculators - Calculates distances, areas, and bearings between geographic coordinates using spherical trigonometry.
• SDK Utility Libraries - Ships a collection of helper classes and wrappers that simplify complex geospatial tasks within the Google Maps SDK.
• Heatmap Renderers - Generates density-based heatmaps by aggregating point weights and applying a color-ramp visualizer.
• Shape Drawing - Renders polygons, polylines, and circles to highlight areas or define paths on the map.
• Map Point Clustering - Groups nearby map markers into single aggregate icons to reduce visual clutter.
• Marker Placement - Positions custom icons at specific geographic coordinates to identify locations on the map.
• Spherical Distance Calculators - Implements algorithms for calculating distances between coordinates on a spherical earth model.
• Geospatial Visualization Libraries - Offers libraries optimized for rendering heatmaps and clustered markers in mobile environments.
• Marker Clustering - Implements a marker clustering system that groups nearby coordinates into single icons to reduce visual clutter.
• Interaction and Event Handling - Implements event routing logic to handle user interactions with map overlay elements.
• Map Marker Layers - Provides high-performance, customizable markers by associating map instances with specific identifiers.
• KML Interaction Handling - Responds to user click events on specific geometry features within a KML layer.
• Map Visual Styling - Provides tools to apply cloud-based visual themes and styles to maps via map identifiers.
• Data-Driven Styling - Enables map visuals to be customized based on geographic boundaries or datasets linked to cloud configurations.
• Marker Visuals - Generates custom marker icons containing text and styled content to display information on the map.
• Polyline Decoding - Provides utilities to compress and decode sequences of latitude and longitude coordinates into compact polyline strings.
• Polyline Encoding and Decoding - Converts sequences of latitude and longitude coordinates into encoded strings and vice-versa for efficient transmission.
• Polyline Encoders - Compresses latitude and longitude sequences into compact ASCII strings for efficient data transmission.
• Interactive Map Workflows - Defines UI patterns and behaviors that respond to geographic interactions, camera controls, and map events.
• Map Event Listeners - Triggers specific actions in response to user interactions such as map clicks, camera movements, or overlay events.
• Map View Controllers - Controls the map viewport by programmatically adjusting the camera position, zoom level, and bearing.
• Map Data Overlays - Layers custom image tiles over the base map to integrate external data and local imagery.
• Image Overlays - Allows placing custom image grids over specific geographic bounds as map overlays.
