Google Maps Overlay - useful for Japan BernhardMuc 8/20/05 7:26 AM
Hello everybody,

Here's a network link for Google Earth which will use Google Maps to give you a transparent map overlay for the area you are viewing in Google Earth. This is a rather pointless exercise for most parts of the world where the information content in both services is about the same, but for Japan Google Maps provides a lot of additional information.

When I was entering placemarks for my recent holiday in Japan I noticed that Google Earth resolution (outside Tokyo) and additional information (roads, mountains, lakes) is fairly limited but the map view in Google Maps shows all of Japan with excellent detail. So here's my attempt at integrating those two services by putting a transparent Google Map over the Google Earth view. Generating the links to Google Maps was fairly straightforward, but getting the alignment right was quite a challenge.

To try it out, just point Google Earth to somewhere in Japan and open the attached KMZ file. You can go somewhere else as well, but you'll get error messages if an area is not available at the required zoom level.

I just signed on here and this is my first post, so I apologize if this should go into another forum or if it has been discussed before.

Cheers,
Bernhard

P.S.: By the way, has anyone noticed how the name of Mt. Fuji changes almost daily? Today it's "Huzi San"

COOL!!!!!
I had partially overlayed it up to now. The map can be confirmed to any place in the future.
It is very very wonderful data. Thank you.

!
that has to be one of the best add-ons to this already wonderful gadget - great first post (I assume it doesn't already exist as I was looking for this only a week or so ago)
p.s. It works well for the UK which was the area that I was interested in.

Great work
Excellent for most countries.
Could you summarize how you did it?
much appreciated.

Help, t didn't work for me

The only big problem is the "Image not found" spam when you are looking at an area for which they don't have maps. Don't know if you could do something about that or if its GE's job.

Hello Bernhard,

great job - verry impressive

It would be useful for the rest of the world - outside Japan - if you could release a satellite version . . .

Image errors and 'safe' KMZ BernhardMuc 8/22/05 12:11 PM
The problem here is that my script just generates links to map tiles on the Google Maps server, but it doesn't know if these tiles exist since they are fetched by GE after the network link has been refreshed.

The whole world seems to be available down to level 8 with the following exceptions:
- Canada: level 2-0
- Japan: level 0
- UK and Ireland: level 0
- USA: level 1-0

The simplest solution to the problem is in the attached KMZ - just sets the minimum zoom level to 8. This should work anywhere but it's also very boring, perhaps people can use it for troubleshooting. If you use the script in a certain area you might try out the smallest zoom level that you can use without errors and then use this number as the ZMIN parameter in the network link location.

Now I could try to limit the zoom factor depending on the area, but then if Google Maps adds new data people couldn't use it before I change the script. (and people couldn't use the script to look for areas with new data).

Another suggestion would be that GE removes the "Could not load image" message boxes - the "Image not found" picture should be enough to inform the user. Maybe there's also a Windows utility which can automatically click away certain message boxes...

Hi Anton,

do you know a server for satellite pictures that I could link to legally?

Try the 'safe' KMZ above BernhardMuc 8/22/05 12:21 PM
You could try the "safe" KMZ from my reply to Hulk above
Re: Google Maps Overlay - useful for Japan macnetz 8/22/05 12:31 PM
Hi Bernhard,

I meant the satellite part of Google Maps, like here (runs only with Firefox - no IE)

How it works BernhardMuc 8/22/05 12:56 PM
Here's a short summary on how it works:

The KMZ contains a network link to an HTTP server. When the view stops, GE makes a request to the server and sends the coordinates of the area on the screen. The request is handled by a PHP script which calculates the middle point of the screen and the approximate zoom level. Then it sends back a KML file with 25 transparent image overlays around the middle point. These image overlays are links to map "tiles" on the Google Maps server with the tile coordinates and the zoom level inserted. When GE has received the KML file it loads these image overlays and they appear on the map.

The network link location in the KMZ looks like this
...mapover.php?ZMIN=0&ZMAX=14&TRANS=80
and you can influence the script by changing the parameters:
ZMIN=... minimum zoom level (0 is most detailed)
ZMAX=... maximum zoom level
TRANS=.. transparency level (two hex digits, 00 is invisible, ff is opaque)
Re: Satellite pics... BernhardMuc 8/22/05 1:08 PM
Hi Anton,

do you know any part of the world where the satellite pics in Google Maps are better than the ones in Google Earth? The Marienplatz looks quite the same

Cheers,
Bernhard

Hi Bernhard,

you're right
my need for the satellite version is just for fun

Any idea where to get japan google earth overlay?
Google Maps Overlay - updated BernhardMuc 5/3/06 11:33 AM
Hi Mike,

I tried the link right now and it worked for me, maybe try it again later.

By the way, I just updated the script to take advantage of the latest Google Maps update - now there's street level detail for most of Europe, too.

Cheers,
Bernhard

Hi everybody

Japanese blog site at j...@foo, released perfect Google Maps Overlay CGI.
I get this cgi and installation my website.

Neither Google Maps overlay links are working any more.

Anyone know of any others out there?

Possibly the best network link in a year!
This is great.

looks like the network link doesn't load data from GM anymore;-(

anyone knows what's up with that? or is it just temporary???

akanemaru,

Maybe yours works well in Japan, but it went crazy in Juneau, Alaska with endless missing data alerts.
Re: Google Maps Overlay - useful for Japan PriceCollins 9/20/07 11:47 PM

Outstanding

I was able to see the Japanese street names, and it was a great overlay map for Juneau Alaska with TERRAIN TURNED ON It shaped itself to the mountains just fine, and it didn't go crazy when I changed the compass direction and angle of view.

It's very useful to quickly see place names and street routes to determine where the two systems agree and differ.

Now if only we had slider controls for the Maps transparency and level numbers
Re: Google Maps Overlay - useful for Japan Frank4 9/21/07 5:54 AM
Just wanted to point out that Bernhard also wrote the very excellent GlobeGlider.net which lets you link Google Maps or even Virtual Earth directly to Google Earth. If you change your browser setting to let it use the internal browser of GE, and start up GlobeGlider there. You can move either the map or the GE view and it will automatically synchronize between the two. Especially cool if you do it with Virtual Earth Bird's Eye views, or the new VE 3D views.

Read more at GEB.

Better yet: there is a video demonstration of it in action.

Any chance the new Terrain layer could be viewed?

Great idea, Peter! Just enabled it on the server.

Simply edit the network link and add the parameter 'TERR=Y' to the link, for example like this:

http://bernhard.sterzbach.de/ge/mapover.php?ZMIN=0&ZMAX=14&TRANS=80&TERR=Y

Enjoy,
Bernhard
Re: Google Maps Overlay - Terrain sugarsmax 12/6/07 11:20 AM
Works like a charm!
I prefer 100% transparency, and "Update on Request"

Looks like the new Contour lines are not showing.... Perhaps a specific call needs to be made to the server?

Google Maps Overlay seems to be not working today MikeMonett 12/3/08 4:59 PM
Bernhard,

I'm sending you a personal e-mail as well as posting this here....

I created a Google Earth map that your Google Maps Overlays are very compatible with.

Here are the details:

http://docs.google.com/View?docid=dgcrpw3z_2g2vwpqgk

( or, https://www.mydocsonline.com/pub/mikemonett/Dayton-areaBikeTrails.htm )

All day today, your application has seemed to be not working.

( The array of tiles are just red Xs, because the urls returned are not legitimate Google Map tiles. )

example:

http://mt.google.com/mt?v=w2.86&%78=34878&%79=49731&zoom=0 returned

instead of something like:

http://mt1.google.com/mt?x=34878&y=49731&zoom=0

Is this a temporary or a permanant problem?

If it is permanant problem with your server, would you be interested in sharing your application so that I could place it on my server?

( at https://www.mydocsonline.com/pub/ )

Thanks for creating this very impressive tool.

Sincerely,

Mike Monett
Dayton, Ohio
