ESRI
Personally, I would steer clear of the ESRI stuff. I'm working with ESRI Geodatabases and find the restrictions perplexing and restrictive. The Enterprise offering may be different, but I choose not to hold my breath. (This is a biased opinion, and I'm suggesting you do some research and make your own decision here. I have little experience with ...

GEE really is a visualization platform, not a enterprise GIS. With a true GIS you also have the need/ability to create data and do more complex analysis with it aside from draping it over a globe. I have worked with systems where GEE was a compliment to our ESRI systems; so we didn't use ArcGIS Explorer to view the data, the users used Google Earth. You can ...

Apart from, as @underdark says ST_Length() returns a cartesian distance between the two points which in an unprojected CS is meaningless in this case, I would go with the answer you get from PostGIS. Google Earth uses a spherical globe, whereas the WGS84 globe is a spheroid - it is slightly squashed at the poles. Over short distances, there won't be much ...

I think the problem is your time span. Its supposed to be in the format
YYYY-MM-DDThh:mm:sszzzzzz (see KML Ref)
"1944-06-06T06:2010-10-26T06:30:08
"
is wrong in the "mm" part. Also, if you're trying to animate a set of time periods rather than points, you need timestamp rather than span.
Time should be before and after according to the documentation ...

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 ...

Kannel is the most known sms gateway (Free and Open Source), it runs both in Linux and Windows. You can connect it with a GSM modem or a mobile phone to send or receive sms (or MMS). If you have a GPS who can connect to GSM you have the solution. AND of course it connected with Mysql or Postgresql and more DB. From a database you can send the data to a web ...

Apparently, the measurment ruler is not accurate over long distances > 5,000 km.
Google's offical stance says, "makes no claims as to the accuracy of the coordinates in Google Earth. These are provided for entertainment only and should not be used for any navigational or other purpose requiring any accuracy whatsoever".

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)

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

Google Earth is mostly nice visualization, not serious GIS.
And may be that's a reason why you dont see much of it being discussed here :)
ESRI AGS on the other hand is a Industry Standard GIS...super serious stuff, tons of features out of the box, plus plethora of customization options make it the numero uno choice for most of the enterprise GIS ...

Google Earth can display a number of file formats, which may be generated programmatically, but in general the user controls the interaction.
The Google Earth Plugin can use the rich set of tools available for web development, and allows DOM manipulation of the data used within the earth environment. You can interact with the user environment, modifying the ...

Bill Huber gave the right answer in the comments. I delayed the answer by running the NGS inverse tool incorrectly.
It looks like confusion between latitude and longitude order. I did put the coordinates in the wrong order when I used the NGS inverse tool. Stupid of me! If I enter values correctly, the geodesic distance is 256414.3059 m. If I enter the ...

You will need a KML file of the world borders as polygons. A quick Google turned up this Which seems to be pretty much what you want.
I'm not sure if there is a water polygon in that dataset, so you may still have the sea floor. If that's the case, you'll need to import the KML file into something like Quantum GIS, create a rectangular polygon covering the ...

Would Gammu SMS Daemon http://wammu.eu/smsd/ be a start?
Gammu SMS Daemon is a program that periodically scans GSM modem for received messages, stores them in defined storage and also sends messages enqueued in this storage. It is perfect tool for managing big amounts of received or sent messages and automatically process them.
You can currently ...

Render your own using POV-Ray, a ray casting engine that can make images of any arbitrary size. Here's an example earth centered on Southern California:

If you don't need satellite imagery or 3D stuff it's possible with a combination of:
OSM data imported in Postgresql/Postgis (via osm2pgsql)
Mapnik used to render map tiles
OpenLayers used to display the web map (serving tiles rendered by Mapnik)
some Javascript middleware (ExtJS) to facilitate retrieving data as required by vector layers and build UI ...

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:

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, ...

If you want to serve the data as static KML, the easiest option is to use ST_AsKML function in PostGIS. However if you want to use live KML data, one option could be using GeoServer and get the output in KML format.

I see two possible options:
Use Google Earth Pro to directly load the raster assuming it is in a supported file format. See Importing Geographic Information Systems (GIS) data in Google Earth
Google Earth supports "super overlays" through the use of Region and NetworkLink elements which allows you to display a multi-megapixel image by subsetting it into ...

goto: http://www.gadm.org/country
Select Malaysia and download
a) as kmz-files : two files level1 and level2 , level2 unfortunately gave me an error when loading in Google Earth
b) as a shapefile. load into qgis and save the different levels as kml files(rightclick in left panel on layer-name and save as) this works well for me in Google Earth

If you are working in the states, you may prefer http://datagateway.nrcs.usda.gov/ as I think neither Google nor ESRI allows to get google maps in your desktop application.
Google in the first place doesn't provide services such as WMS. Please check following links:

This was an interesting article, but I wouldn't suggesting starting a new project along these lines, for the following reasons:
The approach given in the Article uses The COM API, which has been Deprecated. The latest versions of Google Earth, can no longer be controlled by the COM API calls.
Querying an MS access database is way more difficult than using ...

I asked an iPad whiz, and he said that one possible way is to e-mail yourself the kmz file, have your e-mail client open it, and hope that iOS knows to open Google Earth in opening the attachment. He says that iPad has no "desktop" per se, so it doesn't work as one might expect a Mac or PC to work...

This can be done by creating a Network Link KML, with the <refreshInterval> and <viewRefreshMode> (reference) settings set appropriately. As listed in the example, you'll need a script which returns the new response, in this case by sending the query down to PostGIS to respond with an updated asKml result.

This isn't really a response to the initial question about Google Earth Enterprise (which I haven't used) but more to the series of responses already made. I'm comparing Google Earth (not Maps) to the ArcGIS examples I've looked at - maybe ESRI's ArcGlobe can approximate some or all of Google Earth's features.
I identified with Optimize Prime's initial ...

You can find basics information regarding resolution and accuracy on Google Earth wikipedia page.
Most land areas are covered in satellite imagery with a resolution of about 15 m per pixel. This base imagery is 30m multispectral Landsat which is pansharpened with the 15m [panchromatic] Landsat imagery. However, Google is actively replacing this base ...

Create Proportional Symbols for the number of dots. You need to do some modification to suit your needs.

Your first requirement is that you should be able to
Display a web map with topographical details
This won't be that easy with open street maps. With google maps, the 'terrain' view is good enough to show basic topographical details.
With Open street maps, you'll have to have your own server which serves topographical data.

Pretty sure you cannot force ArcGIS Server to generate KML files, as it includes the symbology along with the KML.
Are you simply trying to view the service on your iPad device? If so, have you tried the ArcGIS Javascript link? (i.e. http://host/ArcGIS/rest/services/service/MapServer?f=jsapi) If that doesn't work, I would write/host a simple JavaScript ...
