[GIS] Google earth Borders on Google maps

google earthgoogle maps

Google earth comes with a variety of borders, for example:
International Borders
1st Level Admin Borders
2nd Level Admin Regions

I was wondering if it is possible to render these borders on Google maps, in the same way we can render kml files.

Does anyone know where this information is stored? Is it at Google's end, or having installed Google earth, is it at my end? Are they just KML files?

Thanks

No, it is not possible for you to access the underlying geometry that is used to represent these borders in Google Earth. Nor is it possible to use them separately in Google Maps as KML.

Your best bet would be to find a My Maps layer (if you can find one).

[GIS] WMS + Google Earth + tilted view = alignment failure

I am guessing that you are trying to render a single WMS image to cover the entire view. Remember that when the image is tilted it is very difficult to render a rectangular image of the correct resolution for the entire area. Locations close to the camera need to be rendered differently to features on the horizon. Therefore, direct use of WMS is completely unsuitable for use in Google Earth and should be avoided.

The best approach is to create a network link that divides the area into a set of tiles, each with its own unique link to a fixed extent of the WMS as a Super Overlay. This allows Google Earth to decide which tiles to load and when. It will also make it much simpler to implement caching at the server end. Create larger tiles for different zoom levels using the Region tag. When the view is tilted Google Earth can use lower resolution tiles on the horizon, and higher resolution for closer areas. For an idea of a good structure try converting your data manually using the KML Super Overlay GDAL driver.

For large tiles the WMS response needs to be in WGS84 due to projection issues. For smaller tiles it is sometimes possible to use a local projection system by individually calculating the WGS84 coordinates of the tile corners. There are obvious projection issues, although the results are often better than interpolating.

[GIS] Color matching between Google Earth and Google Maps (same KML)

The problem is the KML structure. Google Earth more flexible with the KML structure when Google Maps doesn't.

All the "Style" tags should be inside the "Document" tag and outside the "Folder" tag.

Here's a short KML example:
