Implementing .NET MAUI Maps (SfMaps)

A comprehensive skill for implementing Syncfusion® .NET MAUI Maps control. The SfMaps control is a powerful data visualization component for displaying statistical information across geographical areas with highly interactive and customizable features.

When to Use This Skill

Use this skill when you need to:

• Install and configure Syncfusion® .NET MAUI Maps (SfMaps) control
• Display geographic data using shape layers with shapefile data
• Integrate tile-based maps from providers.
• Add markers to denote locations with built-in symbols or custom content
• Visualize data with bubbles, color mapping, and choropleth maps
• Display legends for shapes or bubbles with customizable appearance
• Show data labels on map shapes with smart positioning
• Add sublayers (circle, arc, line, polygon, polyline) for additional data visualization
• Enable interactions like zoom, pan, shape selection, and tooltips
• Implement AI-driven location search for smart geocoding and search

Component Overview

.NET MAUI Maps provides two primary layer types:

1. Shape Layer (MapShapeLayer): Renders vector maps from GeoJSON or shapefile data
2. Tile Layer (MapTileLayer): Renders raster map tiles from web map tile services

Key Features:

• Multiple layer support with sublayers
• Markers with built-in and custom templates
• Bubble visualization for data representation
• Color mapping (equal and range-based)
• Interactive legends
• Data labels with smart positioning
• Zoom and pan capabilities
• Shape selection and tooltips
• AI-driven location search

Platforms Supported: Android, iOS, Windows, macOS
