javascript - How to get max zoom for maptype in location -

-

on google maps' js api reference page, says method getmaxzoomatlatlng:

returns maximum zoom level available @ particular latlng satellite map type.

for reason, terrain maptype bottoms out @ level 15 in calgary (for example) satellite maptype can go way zoom 19. have 2 map services running simulataneously, , want maps in sync, can't sync if can't reach same zoom level.

so, i want know when terrain map (or maptype) can't cope, , trigger special case functions.

is there method, or alternative, getting maximum zoom location specific map type (since above mentioned method works satellite)?

well, 1 solution i've decided go in meantime attach zoom-end handler arcgis map (could leaflet well) , maptypeid_changed handler google map.

so, arcgis map (emap) did this:

emap.on('zoom-end', function (e) {   // map zooms synced   gmap.setcenter(esri.geometry.webmercatortogeographic(e.extent.getcenter()));   gmap.setzoom(e.level);    // if google map couldn't it, reset emap   if (gmap.getzoom() !== e.level) {     emap.setzoom(gmap.getzoom());     // runs handler again   } });

and if google map set satellite, changed, needed trigger same check, forced execute zoomend handler:

google.maps.event.addlistener(gmap, 'maptypeid_changed', function () {    // reason, esri has issues setting zoom current zoom   // has run initial check before calling zoomend   if (gmap.getzoom() !== emap.getzoom()) {     emap.setzoom(gmap.getzoom());   } });

hope helps someone, really, i'm looking forward seeing better solution this. seems awfully complicated approach merely firing function if google's maptype can't reach zoom level.
