I have two layers:1)
var layer = new ol.layer.Tile({source: new ol.source.OSM()});2)
var layer_g=new ol.layer.Vector({ projection : 'EPSG:4326', style: new ol.style.Style( { fill: new ol.style.Fill({color: [0, 255, 0, 0.2]}), stroke: new ol.style.Stroke({color: 'black', opacity: 0.1}) } ), source: new ol.source.GeoJSON({ url: 'file.geojson', projection : 'EPSG:3857' }) });where file.geojson is:
{ "type": "LineString", "crs": { "type": "name", "properties": { "name": "urn
gc:def:crs:OGC:1.3:CRS84" } }, "coordinates": [[21.919146, 51.962142].....,[21.955264, 51.955445],[21.955894, 51.955762],[21.956169, 51.955924],[21.957933, 51.956962] ], "properties": { "distance": "9.783024", "description": "To enable simple instructions add: 'instructions=1' as parameter to the URL", "traveltime": "653" }}I add these two layers to map:
var map = new ol.Map({ layers: [layer,w_gminy], target: document.getElementById('map'), view: view});But only OSM layer is visible.
Is the problem in a structure of geojson file?
