kml

问题 Recently I'm developping a Map containing KML Layer compressed as KMZ file (about 45mb). As there is a file weight limitation, I first split the files into 3mb files. Then I noticed that some splitted files was not showing everytime, causing some "blanks" on the map. So I made researches on many forums, and found that the real limitation of files in order to get everything working properly is 2mb. After update, the KML Layer was indeed showing entierely. However, after doing many tests, I

问题 I have this simple script on a web page, loading a small kml file, but when I add geolocation, it always centers the map on the current location. And I want to load the map centered on the kml file. User location should only be displayed if he is in the area of the kml, or if he drags the map to the area where he is located. Accessorily, is there a way to easily refresh the user location on the map with javascript (maps api 3), without re-centering the map ? var map; function initialize() {

问题 I am trying to add a custom icon for the marker after parsing a kml file with geoXML3, but I cannot figure out how. I cannot add specifications in the kml files, so I am trying to do it with Javascript. I didn't manage to find any useful documentation about it. This is my kml loading: myparser.parse('http://mywebsite.com/myparser/last_feed/now.kml'); var myparser= new geoXML3.parser({map: map,zoom:7,icon: image}); 回答1: To change all the marker icons using geoxml3, set the markerOptions.icon

问题 I'm trying to geolocate these 27 points at the same time, in the same row. But the process returns only the first 10 points, even if in the preview they are all 27 correctly geolocated. Why? Is there a particular limit to the number of points I can locate? <Point><coordinates>7.680237,45.064504,0.0</coordinates></Point> <Point><coordinates>7.681675,45.061957,0.0</coordinates></Point> <Point><coordinates>7.685044,45.060768,0.0</coordinates></Point> <Point><coordinates>7.686482,45.06029,0.0<

问题 I am trying to figure out how to use Google Maps API v3 to label a kml polyline that was originally created in ArcGIS Desktop. Unfortunately, the examples that I came across thus far either don't seem to apply to kml files, had dead links, or were examples on how to create pop-ups. If anyone has an example of how to create labels (not popups) from a kml file let me know. Side questions: *In ArcGIS I can use Layer->Properties->HTML Popup to configure the popup for kml. What do I need to do in

问题 I have my map, in 3d and I want to style it so that only counties with markers have a certain color. I also want to change the boundary color. I am using v3 of the Google Maps Api to load the earth. Is there a way to customize the map (3d) and also change the color of the borders in the in-built layer. Example 3d map 回答1: The borders layer you refer to is simply on or off, there are no methods to style it or alter its behaviour. If you wish to have a custom data layer to show borders then you

问题 I'm not a javascript guru, so this project I"m working on has been pretty challenging. I've managed to gather up various bits of code to create my map, and I'm almost there, but am stuck on the homestretch. I'm trying to get the KML files I'm referencing to load up as soon as the page is opened. I've tried setting the checkboxes to "checked", but that doens't work either. To get the KML to load, I have to uncheck and the re-check the box. It's probably something simple, but I've tried
