Svrnty.GeoManagement.Abstractions

Core abstractions and models for geocoding and address management services.

Overview

This package provides the foundational interfaces and data structures for implementing geocoding providers. It defines the contract for geocoding operations without being tied to any specific provider implementation.

Installation

dotnet add package Svrnty.GeoManagement.Abstractions

Key Components

IGeoManagementProvider Interface

The main interface for geocoding operations:

public interface IGeoManagementProvider
{
    // Convert address to coordinates
    Task<GeoPoint?> GetGeoPointAsync(Address address, CancellationToken cancellationToken = default);

    // Convert coordinates to address
    Task<Address?> ReverseGeocodeAsync(GeoPoint geoPoint, CancellationToken cancellationToken = default);

    // Normalize and validate an address
    Task<Address?> NormalizeAddressAsync(Address address, CancellationToken cancellationToken = default);
    Task<Address?> NormalizeAddressAsync(string address, CancellationToken cancellationToken = default);
}

Address Model

Represents a structured postal address:

public record Address(
    string Line1,
    string? Line2,
    string City,
    string Subdivision,    // State/Province
    string PostalCode,
    string Country,
    GeoPoint? Location,
    string? Note,
    bool IsNormalized = false
);

Features:

• Formatted address output with GetFormattedAddress() method
• Support for multiple formats: Full, Compact, MultiLine
• Optional location coordinates
• Normalization tracking flag

GeoPoint Model

Represents geographic coordinates:

public record GeoPoint(double Latitude, double Longitude);

Usage

This package is designed to be used with provider implementations. For example:

using Svrnty.GeoManagement.Abstractions.Abstractions;
using Svrnty.GeoManagement.Abstractions.Models;

public class MyService
{
    private readonly IGeoManagementProvider _geoProvider;

    public MyService(IGeoManagementProvider geoProvider)
    {
        _geoProvider = geoProvider;
    }

    public async Task<GeoPoint?> GetCoordinates(Address address)
    {
        return await _geoProvider.GetGeoPointAsync(address);
    }
}

Available Providers

• Svrnty.GeoManagement.Google - Google Maps Geocoding API implementation

Implementing a Provider

To create your own geocoding provider:

1. Reference this package
2. Implement IGeoManagementProvider
3. Map provider-specific responses to Address and GeoPoint models

public class MyCustomProvider : IGeoManagementProvider
{
    public async Task<GeoPoint?> GetGeoPointAsync(Address address, CancellationToken cancellationToken = default)
    {
        // Your implementation
    }

    // ... implement other methods
}
