format: new ol.format.GeoJSON({ defaultDataProjection: 'EPSG:4326', featureProjection: 'EPSG:3857' }),
url: 'trees.geojson'
}},
style: new ol.style.Style({
image: new ol.style.Circle({
radius: radius,
fill: new ol.style.Fill({
color: 'red'
}),
stroke: new ol.style.Stroke({
color: 'white',
width: radius / 4
})
})
})
});
