Quick Start

Installation

Install the core package via NuGet:

dotnet add package Datalogy.Gis.Core
dotnet add package Datalogy.Gis.Domain

For data providers:

# SQLite/Spatialite
dotnet add package Datalogy.Gis.Data.Sqlite

# PostgreSQL/PostGIS
dotnet add package Datalogy.Gis.Data.Postgres

# Azure Cosmos DB
dotnet add package Datalogy.Gis.Data.CosmosDb

Basic Usage

using Datalogy.Gis.Core;
using Datalogy.Gis.Domain.Entities;

// Create a feature with geometry
var feature = Feature.Builder()
    .WithPoint(longitude: 28.9784, latitude: 41.0082)
    .WithAttribute("name", "Istanbul")
    .WithAttribute("population", 15_460_000)
    .WithAttribute("country", "Turkey")
    .Build();

// Save to database
await repository.InsertAsync(feature);

// Query by bounding box
var features = await repository.QueryBBoxAsync(
    minLon: 28.0, minLat: 40.0,
    maxLon: 30.0, maxLat: 42.0
);

Examples

MAUI Application

using Datalogy.Gis.Maui.Controls;

// In your XAML
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:gis="clr-namespace:Datalogy.Gis.Maui.Controls;assembly=Datalogy.Gis.Maui">

    <gis:MapView
        CenterLatitude="41.0082"
        CenterLongitude="28.9784"
        ZoomLevel="10"
        MapTapped="OnMapTapped" />

</ContentPage>

@using Datalogy.Gis.Blazor.Components

<MapComponent
    CenterLatitude="41.0082"
    CenterLongitude="28.9784"
    ZoomLevel="10"
    Width="100%"
    Height="600px"
    ShowZoomControls="true"
    OnMapClick="HandleMapClick" />

Spatial Queries

using Datalogy.Gis.Data.Postgres;

// Query features within radius
var nearbyFeatures = await repository.QueryRadiusAsync(
    centerLon: 28.9784,
    centerLat: 41.0082,
    radiusMeters: 5000
);

// Spatial join
var featuresInPolygon = await repository.QueryIntersectsAsync(polygon);

// Buffer operation
var buffered = geometry.Buffer(distanceMeters: 1000);
