## What it is
An open-source Kotlin utility library extending the Google Maps SDK for Android with features like marker clustering, heatmaps, KML/GeoJSON import, polyline encoding, and spherical geometry calculations. It is split into focused submodules and published on Maven Central.

## Use cases
- cluster thousands of markers on an Android map
- render GeoJSON data as a styled map layer
- display KML files on a Google Map
- add a heatmap layer to visualize point density
- compute distances, headings, and areas between lat/lng points
- encode and decode polylines for Maps API interoperability
- animate a marker between positions
- check Street View availability at a location

## When to choose
- you use the Maps SDK for Android and need clustering, heatmaps, or data-layer imports
- you need spherical geometry helpers for geographic math on Android
- you want a maintained, official Google utility library with modular dependencies

## When to avoid
- you use Mapbox, OSM, or a non-Google mapping SDK
- you target Android below API 23
- you need iOS or web mapping utilities instead

## Facets
- artifact type: library
- maturity: stable
- function: geospatial, data-visualization, image-processing
- domain: mobile-development, android-tools
- platform: jvm
- tags: google-maps, marker-clustering, kml, geo, heatmaps, spherical-geometry, polyline-encoding, utility-library, maps, geospatial, android
