How to create map from GeoJson shape file using .NET MAUI Maps?

This article describes how to create a map from GeoJSON data or a shapefile in the Syncfusion® .NET MAUI Maps control.

The Syncfusion® .NET MAUI Maps supports both shape and JSON files. you can load from various sources.

• FromFile returns a MapSource that reads a shape source from a local file.
• FromUri returns a MapSource that downloads and reads a shape source from a specified URI.
• FromResource returns a MapSource that reads a shape source file embedded in an assembly.
• FromStream returns a MapSource that reads a shape source from a stream that supplies source data.

How to load an embedded file

• You can load both the JSON data and the shapefile.
• For example, placing australia.json in the root folder of a project named MyProject will result in a resource ID of MyProject.australia.json. Similarly, placing world1.shp in the Assets folder of a project named MyProject will result in a resource ID of MyProject.Assets.world1.shp.
• Right-click the added shapefile and navigate to properties.
• Choose the EmbeddedResource option under the BuildAction of the respective shapefile.

The following code sample demonstrates how to load a shape file from an embedded.

C#

SfMaps map = new SfMaps();
MapShapeLayer layer = new MapShapeLayer();
layer.ShapesSource = MapSource.FromResource("GeoJsonMap.ShapeFiles.world1.shp ");
map.Layer = layer;

The following code snippet demonstrates how to load a JSON file from embedded.

C#

SfMaps map = new SfMaps();
MapShapeLayer layer = new MapShapeLayer();
layer.ShapesSource = MapSource.FromResource("GeoJsonMap.ShapeFiles.world-map.json ");
map.Layer = layer;
