How to add Geoserver WMS layer to vtm

[Ali Mahdian]

Hi,

I am using VTM 0.15.0 and want to add a WMS layer to my map. This is my code:

MyUrlTileSource class:

public abstract class MyUrlTileSource extends TileSource {

    ...

...

...

    private static class DefaultTileUrlFormatter implements TileUrlFormatter {

        @Override

        public String formatTilePath(MyUrlTileSource tileSource, Tile tile) {

            int x =tile.tileX;

            int y = tile.tileY;

            int zoom = tile.zoomLevel;

            double minLon   = tile2lon(x, zoom);

            double minLat   = tile2lat(y, zoom);

            PointXY minPointStr = ConvertCoordinate.wgs2webMercator(minLat,minLon);

            double minX = minPointStr.getX();

            double minY = minPointStr.getY();

            double maxLon   = tile2lon(x + 1, zoom);

            double maxLat   = tile2lat(y + 1, zoom);

            PointXY  maxPointStr = ConvertCoordinate.wgs2webMercator(maxLat,maxLon);

            double maxX = maxPointStr.getX();

            double maxY = maxPointStr.getY();

            String url = "/GeoServer/sdi/wms?service=WMS&version=1.1.0&request=GetMap&layers=sdi%3Adehestan&bbox="+minX+","+maxY+","+maxX+","+minY;

            return url;

            

        }

    }

}

MainActivity class:

 @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        mMyBitmapTileSource geoserverLayer = MyBitmapTileSource.builder()

                .url("http://IP_ADDRESS:8082")

                .tilePath("/{Z}/{X}/{Y}.png")

                .build();

        geoserverLayer.setApiKey(null);

        mMap.layers().add(new BitmapTileLayer(mMap, geoserverLayer));

    }

You may need a custom tile source to translate the GeoServer into valid tiles to be rendered with this map library.

osmdroid-wms has an implementation, you can study and customize it.

The Geoserver produce a valid mapbox tile : https://docs.geoserver.org/latest/en/user/extensions/vectortiles/tutorial.html

" GeoServer can also produce vector tiles in three formats: GeoJSON, TopoJSON, and MapBox Vector (MVT). These are also supported by OpenLayers and other clients."

url: '/geoserver/gwc/service/tms/1.0.0/' + layer + '@EPSG%3A'+projection_epsg_no+'@pbf/{z}/{x}/{-y}.pbf'

VTM can decode and render online vector tiles, e.g. OpenMapTilesMvtActivity, MapilionMvtActivity.

You may need a new tile source for this tile provider.
