    map.setSpatialReference({
            projection:'EPSG:4326',
            resolutions: (function() {
                const resolutions = [];
                for (let i=0; i < 19; i++) {
                    resolutions[i] = 180/(Math.pow(2, i)*128);
                }
                return resolutions;
            })()
