I have a site that contains kml. The kml is shown as a layer in Google Maps. The maps are on the same site. Until recently (may 12th), this worked fine, but now it stopped working. The kml itself is OK, it can be used in Google Earth. When I copy the kml to another site I can load it in Google Maps without any problem.
Is it possible that my site is on a "blacklist" for some reason? Traffic is low. I did not use an API key. I do now but that did not solve the problem.
You can see the difference here:
1 - with kml from my site
2 - with kml placed elsewhere
The first one fails, the second one works. The kml placed elsewhere is an exact copy of the kml from my site. The kml from my site is served with media-type application/vnd.google-earth.kml+xml. It is dynamically generated.
In my case i got FETCH_ERROR on kml status-
Because my site allow only tls 1.2 secure connection.
When i put the files on another server- it's work.
Update 1-
It happend again after sometime, this time use the same domain helped.
from the Google Maps documentation
From February 2015, maps created in the classic Google Maps — https://maps.google.com/ — will no longer load KML/KMZ files from external websites. However, we know that KML files are a really useful way to work with geographic data, so we’ve added KML to Google My Maps, and continue to support this format with other Google Maps APIs. We hope that one of these options will meet your needs.
Both are valid, the one that doesn't works returns a KmlStatus of FETCH_ERROR. As a guess, I would say that the dynamic generation is taking too long. But there might be some security on your server that is preventing Google's server from fetching it.
from the documentation
FETCH_ERROR The document could not be fetched.
from your site
doesn't work with Google Map KmlLayer
Returns KmlStatus: FETCH_ERROR
Works through a proxy with the third party parser geoxml3
placed elsewhere
works with Google Maps KmlLayer
The problem automagically solved itself by waiting a few days. We can only guess what caused it, maybe a temporary glitch on our server which caused Google to stay away for a while and/or sploil it's cache. Anyhow, thanks for the reactions, at least I learned something about testing my kml.

I'm trying to create a link in a web page that permit to open google maps and/or google earth loading the kml file specified.
I see here geouri method but don't seems working anymore with kml file
I also saw for example this:
https://earth.google.com/web/?kml=https://tourbuilder.withgoogle.com/tours/ahJzfmd3ZWItdG91cmJ1aWxkZXJyEQsSBFRvdXIYgICg6vjqywkM/earth
but this method seems working only with specific sites like tourbuilder, and for what I need, kml generated dynamically from the web pages, possibly updated over time and numerous kml (almost 200) would take a long time to create a "tour" for each (if that is possible) and would restrict the possible changes to the web page and to kml.
Can someone tell me if there is another way to create a link in a web page that permit to open google maps and/or google earth loading the kml file specified please?
Maps.google.com used to support loading public KMLs via the search bar or via a URL parameter, but not anymore. To load a KML in Google Maps, you need a web site (can be very simple) that uses the Maps API and loads a KML Layer. Sounds like not your use-case, but if it was a simple KML that wouldn't be changing often, you could consider uploading it to a MyMap and sharing that.
Google Earth for web & mobile (as opposed to the Earth Pro desktop application) does not currently support loading arbitrary KMLs via URL either, except for certain KML sources (as you saw with tourbuilder).
I've created KML files of some world regions for display using the Google Maps API. This has been working fine, but one region has recently started displaying as if the data's corrupt. You can see what I mean here:
https://drive.google.com/file/d/0B9u3tNbtEyFRMTdwQTdEa0U5S2s/view?pli=1
If I load the same KML in Google My Maps it still displays correctly:
https://www.google.com/maps/d/viewer?mid=z8mYjxPmAgBQ.kGn7mza0JOSU
It used to display fine, but now even if I roll back to previous versions of the file it displays in this weird way.
The KML regions are created using QGIS's Vector > Geoprocessing Tools > Dissolve tool to merge countries (to shp files), which I then save off as KML. Data is from Natural Earth's ne_50m_admin_0_countries data set.
Does anyone know what might be going wrong?
I would say that the Google Maps KML rendering engine has some issues. It works when I use the geoxml3 third party parser to render it, but not when I use the Google Maps Javascript API v3 KmlLayer to render it.
rendered with geoxml3
Note that the performance with third party parsers will depend on the complexity of the KML. Tile base rendering like used in KmlLayer will almost always perform better.
issue #8003 in the Google Maps Javascript API ve issue tracker
I thought I was going crazy. This was working for years until some days ago.
I agree it seems to be where polygons cross the "international date line" or anti-meridian. I see straight lines horizontally across the map.
Furthermore I swapped out my KML file for another from a different source, SAME problem. Thanks for restoring my sanity, I wasted a stressful day trying to fix this, I think it is a Google problem. ps. they work fine in Google Earth.
I would like to di splay a Google Map with a kml inside through API v3. the proble is that every one can see the url of the kml and easily download it. Is there a trick to 'hide' the .KML URL?
wikimapia.org seems to do something similar displaing kml polygons but if you check with Firebug through the script tag you won't see the kml URL.
thanks everyone for help.

You could generate it at run time, so that the server sends the page the URL. However, it is still discoverable at some point. Security through obscurity just doesn't really work. The KMLLayer Layer requires your KML to be on a public server. You could instead parse the KML and render it that way, say using egeoxml. However that delivers much less performance.
I'm writing an HTML5 mobile application that uses Google Maps V3 with a custom layer of OpenStreetMap tiles.
The OSM tiles (from tile.openstreetmap.org) are set to cache for just over 24 hours, and I'm using a cache-manifest for all my HTML/JS/CSS.
So the application could in theory be used offline, except the Google Maps interface isn't happy when offline.
It always wants to call to the Google Maps server at http://maps.google.com/maps/api/js?sensor=false®ion=GB - when this fails, Google Maps fails to load.
Is there any way to use Google Maps V3 API offline?
Could I cache-manifest http://maps.google.com/maps/api/js?sensor=false®ion=GB, or would that be a bad move?
(Sorry for this rather beginner question, let me know if I can explain better!)
Google coders themselves have tackled this problem and unfortunately the information isn't well disseminated. But yes you can use cache-manifest to do exactly what you've described.
Required Readings
First take a look at the Google Code blogpost here: http://googlecode.blogspot.com/2010/04/google-apis-html5-new-era-of-mobile.html
Then have a read at Missouri State's own post: http://blogs.missouristate.edu/web/2010/05/12/google-maps-api-v3-developing-for-mobile-devices/
The Technique
You must cache every URL used by Google Maps
Employ methods to battle Chrome's and Firefox's stubborn caching methods by removing it from "offline websites"
All customizations must be client-side in javascript
Your cache file will look like (as per Missouri State):
CACHE MANIFEST
/map/mobile/examples/template.aspx
/map/mobile/examples/template.css
/map/mobile/examples/template.js

Caveats
You will need to be entirely HTML5-based and recognize the impacts this will have on your users. This situation is handy where either your users are up-to-date on browser standards/devices or you have control over user choices.
Hope this helps.
I have http://maps.google.com/maps/api/js?sensor=false in the CACHE section of cache.manifest, together with my application files and there isn't any problem.
Although, I believe you also have to cache other files that the Google Maps API requests. You can take a look at the files downloaded by your app and include them.
Not possible!
Google map CDN URLs have dynamic nature,
https://mts0.googleapis.com/vt?pb=!1m4!1m3!1i8!2i234!3i15...
https://mts1.googleapis.com/vt?pb=!1m4!1m3!1i8!2i233!3i155!!...
No wildcard characters are allowed in CACHE section of the HTML5 cache manifest files
We can not have some thing like,
CACHE MANIFEST

I had a google map project that I needed offline. I found Bing Maps (https://www.bingmapsportal.com/ISDK/AjaxV7) is much better offline and switched my project over to that and I'm happy. I ran the google and bing version side-by-side in offline mode and Bing was great. Whereas google would immediatey fail on tile loads, Bing maps cached more tiles and appeared to even resize zoomed tiles to at least give you something in offline mode.
I know the question here is about Google maps; but if you don't care about bing vs. google and really just need offline support, I'd highly recommend trying Bing maps. It solved it for me.
this question is kind-of programming related but not exactly - see how we go...
I am trying to view a trip i have made using a gps tracking device onto google maps as one continuous line, however, when i upload the KML file onto google maps it is arbitrarily broken into about 7 different segments.
The trip was made in one go and when shown in google earth it is shown as one continuous line.
I have inspected the KML file and all coordinates are contained within the same single linestring element.
Does anyone know why this is occuring?
Regards
Grant.
It looks like other people have experienced the same problem that you're having, but I was unable to find a solution. It seems that this is just a bug in the Google Maps KML parser.
If you don't mind creating your own map with the Google Maps API, you should be able to parse the file with no problem. There are also some sites like this one which will create a map from your KML file.
