This is a .NET client library for Google Maps Platform web services. It provides a strongly-typed, async-first wrapper around 15+ Google Maps APIs, including Geocoding, Directions, Distance Matrix, Places (New), Routes, Address Validation, Elevation, Time Zone, Roads, Solar, Aerial View, Air Quality, Pollen, and Static Maps. The library is published as a NuGet package (over 2M downloads) and targets multiple .NET frameworks (netstandard2.0, net8.0, net10.0). It follows a consistent request/response pattern with generic constraints for compile-time safety, and includes a built-in engine that handles HTTP serialization, API key injection, error handling, and OpenTelemetry diagnostics (tracing and metrics). An optional dependency injection extension package registers `IGoogleMapsClient` with `IHttpClientFactory`. The repository also contains a comprehensive test suite with a VCR (record/replay) system, benchmarks, mutation testing, and sample applications (Blazor, Console, Minimal API, Generic Host) demonstrating usage.
This is a minimal Node.js library for converting geographic bounding boxes into centerpoint/zoom pairs for static map images, and vice versa. It wraps the @mapbox/sphericalmercator library to perform Mercator projection calculations, caching SphericalMercator instances by tile size and antimeridian flag for performance. The library exposes two functions: 'viewport' computes the center and zoom that best fits a bounding box within given pixel dimensions, and 'bounds' computes the bounding box from a centerpoint, zoom, and dimensions. It supports adjustable tile sizes (default 256) and optional float zooms. The code is well-structured and covered by tests, but the library is simple and does not contain independently reusable subcomponents. It is currently in a stale maintenance state with no recent updates.
