How to create map from GeoJson shape file using .NET MAUI Maps?
This article describes how to create map from the GeoJson data or shapefile in the Syncfusion .NET MAUI Maps control.
The Syncfusion .NET MAUI Maps support 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 an 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 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 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;
Please refer to the following reference links for more information on how to load the shapes from other sources.
