You can save a layer in the KML format directly from QGIS, just right-click the layer name in the Layers window, click Save As.., and choose KML from the list of file formats:

You can not see oil platforms in oceans because Google Earth shows the underwater terrain (bathymetry). In ocean area you see the seafloor. In land or coast area you see an aerial or satellite image.

There are 2 immediate options that would best get you where you are trying to go.
Your first, and probably easiest option, would be to download
Quantum GIS, using the OSGeo4W Installer.
Once you have installed that program, follow this tutorial, which
covers Importing a .csv file to QGIS.
Once you have imported the file, simply right click on the layer in

Instead of creating a KML file then using that to access Google Earth, you can instead add your GeoServer WMS directly as an overlay as below:
From the menu select Add,
select Image Overlay,
give the overlay a name
select the Refresh tab
select WMS Parameters
select the Add button next to 'WMS Server:' drop down
Add the URL to your service (without ...

The resolution of imagery in Google Earth varies depending on the source of the data. When you zoom out, you will see the nice, pretty global coverage produced from a mosaic of many Landsat scenes, which have a native resolution of ~30m (~15m pan-sharpened).
Zooming in, you'll start to get high-resolution in most places. There are many rural areas ...

As Jens said, Google Earth doesn't show you satellite or aerial images for ocean areas. However, the European Space Agency provides global imagery from its Sentinel 2 mission, which covers the oceans and has a high enough resolution to show oil platforms:
Sentinel-2A imagery of Devil's Tower
Sentinel-2A imagery of platforms in the Statfjord oil field

The GEOCONTEXT-PROFILER will create an elevation profile just like Google Earth and you can import a KML and export a CSV. It should give you the same results as Google Earth.
This is the license restriction page that the tool links to.

There is a Google AppSpot website that will let you overlay Google Maps (and many others) in Google Earth for Free
(You do need have a gmail account and allow the site monitor your usage)

As documented on https://developers.google.com/maps/documentation/elevation/start
The Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values).

Elevation values are ...

There are 3 possible reasons what could have happened:
There was actually an island at that location, and is not longer present. The possibility of this is remote.
This could have been a Copyright Easter egg. This is mis-information that is put in a map, so that when someone copies it, you can use it as a red flag to indicate that copying took place. See ...

Maybe is to late to answer the specific question, but I hope that will help someone else:
To identify a platform the historical imagery of Google Earth (GE):
Turn ON Layers -> More -> SPOT Image OR

The bridge is there both in the image but draped over google earth terrain and as a 3D structure. Turn on 3D building.
Note that Google does not allow users to upload their 3D models (previously possible to create and upload with SketchUp a tool now owned by Trimble). The existing 3D buildings and structures have not (YET) been removed, but now new user-...

Thanks everyone for the assistance! After a bit of tinkering around here's what I ended up doing (for anyone else who stumbles upon this):
Convert image to .tif via ImageMagick (included on the CentOS system I'm using).
Used libgeotif's listgeo to extract the metadata from an example GeoTIFF using a similar coordinate/projection space.
Worked out what the ...

Generally speaking, to convert a vector in QGIS you just need to right click on the layer in the TOC and select "save as...". In the dialog that will pop up you need to choose the CRS you need. Be sure that when loading the original vector this has (just check in the vector properties) the right CRS, it is not unusual to have vectors with non explicit CRS, ...

There is a little bit of information which might help you in your task.
First you may need to download FWTools inorder to use geotifcp and listgeo.
Create a TIFF File(You already did it..) Let us call it initialtif.tif
find the image width and height(from where you saved it).
imageWidth = 1016
imageHeight = 551
Create a World File for our initialtif.tif ...

Both Google Earth and Bing map use data from different sources (satellite images and ortho-photos). The horizontal accuracy depends on the source of the datasets and the level of orthorectification. It is usually better near cities than "in the middle of nowhere", but it primarily depends on the data sources. For instance, some countries have agreements with ...

You have almost the same projection in both map. The difference between them is the CRS's unit. You need to create a custom CRS in Settings / Custom CRS using this proj4 setting:
+proj=utm +zone=10 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=us-ft +no_defs
After this, set new CRS in grid layer on properties window:
It should work:

To convert UTM coordinates into geographic latitude + longitude coordinates (WGS84), you can use an online tool such as this one. In your case, "30U" means zone 30 in the northern hemisphere, and using this tool, you should get a latitude + longitude of 1.619158, -2.725228. The Z coordinate is mostly irrelevant here as it is just the height in metres above ...

Google doesn't allow it. There are some folks in the Google Earth Forums that have found some "unofficial" workarounds: http://www.google.com/support/forum/p/earth/thread?tid=4a722cff2ea80a5c&hl=en. Complied from a few posts on those forums:

The heights on google earth refer to EGM96 and are, therefore, Geoidal heights. The lat/long are referred to the WGS 84 ellipsoid.

It is not correct to refer to WGS84 as a 'projection'. Rather it is a datum that is slightly different from a perfect sphere. WGS84 can still be projected onto a Mercator map (as in Google Maps) or a sphere (as in Google Earth). You are simply going between Mercator and spherical. Use the following functions to convert between the two.
(in PHP, should be ...

Save your money, buy nothing. Associate this script with a toolbox tool. Set it up with 4 parameters (Input Raster, Output Folder, Draw Order and Output Prefix). Run. Tried the SuperOverlay thing from GDAL and didn't think much of that horrible data structure. I never cleaned this up so it does processing it doesn't need to if I remember correctly, but it ...

As said in the comments above, the Global Soil Information Facilities (tutorials) website maintained, amongst others, by some of the plotKML authors and contributors gives you everything you need to produce filled polygon areas. In addition to the absolutely correct solution by @Nahm above, here's a reproducible example for future queries on the topic.

Get the x,y coordinates of the boundaries of countries from the following website Natural Earth (thanks, Devdatta Tengshe) which has more accurate data than others I've tried. Then use ArcGIS 10.2 to open the map shape file and select the boundaries you need. Go to data management tools --features-- features vertices to points and open the generated table. ...

You can find a statement of the plugin author with a link to the terms of use here:

is using only the Javascript API with a WebKit Browser.

Your Gauss-Krueger projection uses +datum=potsdam. Up to 2012, this was hard coded in proj4 to a very unprecise value using a 3-parameter-transformation.
You find more exact values for 7-parameter transformations in this topic:

There is an even better ntv2-grid transformation available here (take the ...

The Google Earth Blog (note: this is not officially affiliated with Google) has an article here that might answer your question. It seems that some imagery is added to Google Earth and Google Maps Classic before being added to Google Maps. Edit: I'm unsure if you can point the OpenLayer plugin toward Google Maps Classic rather than Google Maps. Someone else ...

As far as I'm aware, No there is no such feature that performs the actions you are specifically looking for. As a workaround, you could export the layers as KML, import them into My Maps, that will get rid of the folder hierarchy creating a single layer map, and reimporting the custom map to MEL into a new layer.
As a step by step here:
If you want to ...
