问题 I'm layering NOAA radar information over a map with a focus of 8. When the page loads, the map initially renders at 8, then immediately redraws itself to show an entire region. The KML file I'm using contains min/max lat/long coordinates which are used to draw the radar image (in this case over the southeast US area). If I change those coordinates to cover a smaller area, the google map is resized like I want, but radar activity is clipped per the KML file. This is a problem if users zoom out

问题 I am new to iOS, so if any help it will be appreciated. I am trying to get the longitude and latitude from address, earlier the code was working fine but now the JSON data are coming null. Here my sample code, url = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?address=%@&sensor=false",appDelegate.sAddress]; url=[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"Address URL: %@",url); //Formulate the string as a URL object. NSURL

问题 I am currently trying to figure out if there is a way to calculate what is the best time to leave by in order to reach my destination using google maps api. example: San Francisco -> Menlo Park ArrivalTime: 12pm CurrentTime: 11:00am Leave by time: 11:30am Currently distancematrix api seems to fit my needs; however, setting the arrival time or departure time does not give a response with when to leave. So I am wondering, if I am missing something or is there another api within google that can

问题 I've been trying to code a function that returns the most reasonable, moderately sized city/ town/ region a person is in or near. Apps such as yik yak used an algorithim like this to group people together. Is there any existing alogorithims to do this? At the moment I'm using this: geocoder.geocode({'latLng': latlng}, function (results, status) { var city = 'Unknown'; if (status == google.maps.GeocoderStatus.OK) { var details = results[0].address_components; for (var i = details.length-1; i >

问题 I am having trouble clearing any existing polylines before displaying a new one. I've already tried more than 5 different methods (array length = 0, MVCArray clear, polylines.setMap(null), etc) that I found on the web. I am using google maps V3, and here's the code from my js file // initialize the google map var latlng = new google.maps.LatLng(37.775, -122.418333); var myOptions = { zoom: 11, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document

问题 I have a list of markers and would like to get the nearby place using my list of markers. I have tried checking it here but it is not clear as to how they solve the problem. The following is my code that I've implemented so far: public class LocationMapsNearby extends FragmentActivity implements OnMapReadyCallback { private static final LatLng JOHANNESBURG = new LatLng(-26.196908, 28.042179); private static final LatLng CAPETOWN = new LatLng(-33.971294, 18.602129); private static final LatLng

问题 I have little problem with my webpage. When I'm trying to show InfoWindow on marker. That windows shows on the top left corner of a map instead of on the marker. Just like in screen below: Here is my script I use for placing markers and using InfoWindows. var infowindow; function point(name, lat, long) { var self = this; self.name = name; self.lat = ko.observable(lat); self.long = ko.observable(long); var marker = new google.maps.Marker({ position: new google.maps.LatLng(lat, long), title:

问题 I have a google map where I load geometry data* to the data layer using addGeoJson. Everything works fine until i tried to bind an event on polygons in order to change opactiy settings. *I retreive city borders from OSM to draw polygons, I think my json object is well formatted, I took Google as reference : https://storage.googleapis.com/mapsdevsite/json/google.json As soon as I click on a polygon (any of them), it seems to duplicates my polygons anywhere around however the opacity change

问题 I have searched around stackexchange, but I only found questions/answers for changing the location of the pegman. Is there a way to change the source image for it? I have tried affecting the style like this: #map-canvas > div > div:nth-child(8) > div:nth-child(2) > div:nth-child(4) > img:nth-child(1) { background:url(images/man.jpg); } but it's not showing any changes. I can't seem to find it here either: https://developers.google.com/maps/documentation/javascript/reference#StreetViewService
