由 人走茶凉 提交于 2020-01-06 17:56:10
问题 I have about 100k locations stored in a MySQL server. I want to plot this in a map, but when I export it to a .csv file and then convert to .kml file, the file size exceeds 20mb, whereas Google Map API has limits of 3mb for .kml file. The .csv file is about 2.5mb, but I cannot load .csv files into Google Map. Is there any way I can do load the locations to a map? 回答1: Use Google Fusion Tables - they support 100,000 points per layer and 5 layers in toto . They are lightning fast too as you

google maps api : determine if point is inside shape

由 ￣綄美尐妖づ 提交于 2020-01-06 13:52:16
问题 I have created a rectangle on the map along with a listener for bounds_changed . It calls a method to determine if a point is within the adjusted rectangle. However I'm getting the error Cannot read property 'getLength' of undefined when I change the size of the rectangle. This error is coming from the call to containsLocation . In my init: rectangle = new google.maps.Rectangle({ bounds: bounds, editable: true, draggable: true, geodesic: true, map: map }); google.maps.event.addListener

So what I want now is that I can put: <div> <p>Some text.</p> </div> instead of a marker on the map. Thanks! 回答1: Your

Loading kml markers above polygon

由 坚强是说给别人听的谎言 提交于 2020-01-06 12:45:25
问题 I am working with a google map api 3, on my map i want to generate kml markers after polygons, but it is not working, my markers are generate before polygons so i am not able to click marker. 回答1: Native Google Maps Javascript API v3 polygons will always appear on top of KML layers. If you want to control the order, use a KmlLayer to display the polygon as well, add that layer first or control the order with the zIndex property of the KmlLayers. related question: https://stackoverflow.com
