What can this NuGet package do?

Biss.Maps.Common provides the shared map domain and service layer for BISS map integrations. It contains map models, map elements, map interaction events, geometry helpers, and the central BissMapService for handling center/zoom, item rendering requests, and map/user interaction state.

This package is UI-agnostic and intended to be consumed by platform-specific map packages (for example Blazor or MAUI renderers).

What are the core features?

• Map Service State Management - Manage map center, zoom level, map type, visible bounds, and user-position visibility through BissMapService
• Event-Driven Map Interaction - Built-in events for center/zoom updates, coordinate clicks, map item clicks, and render requests
• Map Elements Model - Shared item hierarchy for points, circles, polygons, polylines, and routes
• GeoLocation Abstraction - Interface-based geolocation contract (IBissGeoLocationService) for platform implementations
• Google Geocoding Base Service - BissBaseGeoLocationService with address-to-position and position-to-address conversion using GoogleApi
• Geometry Utilities - GeoHelper methods for distance, midpoint, movement, and polygon area calculations
• DI Integration - Service registration via AddBissMaps with configurable BissMapOptions
• MVVM-Friendly Models - PropertyChanged.Fody-based model notifications where needed

Quick start

1. Register a platform-specific implementation of IBissGeoLocationService.
2. Register Biss.Maps.Common services and configure a default pin image.
3. Inject BissMapService into your ViewModel/service and subscribe to events.

using Biss.Maps.Common.Extensions;
using Biss.Maps.Common.Interfaces;
using Biss.Maps.Common.MapElements;

services.AddScoped<IBissGeoLocationService, MyGeoLocationService>();
services.AddBissMaps(options =>
{
	options.DefaultPinImage = new BmPinImage("https://example.com/pin.png");
});

mapService.SetCenterAndZoom(new BissPosition(47.8125, 16.2425), BissDistance.FromKilometers(2));
mapService.AddMapItems(items);
