Using a combination of JScript and HTML+TIME, Google Earth can be controlled and
animated.
This makes it possible to connect for instance Google Maps, TerraServer USGS, JPL-gm
and other WMS server (China) maps and Google Earth. Channelling point positions
between the applications. It is now very easy to transform on the fly whatever XML
file to a KML data string and load that on the fly in Google Earth using the API.
Update Dec 16th.
Updates till Dec 16th, 2005
This list will disappear in: 120 seconds.
Update Dec20: Panning is now synched with zoom level( one click
is 1/3 of the map). Extra VML elements used
Update Dec19: The Application now has several maps under the
GMpas API which can be interchanged and which are all linked to Google Earth. Different
zoom levels per map type are synchronised. Map control is now both mousewheel and
keyboard, zoom and pancontrol on map deleted.
Update Dec18: Added a China maptype(zoom 0 to 17) after www.step1.cn/map/.
Navigation inChina maps and GEarth simultaneously.
Update Dec16: Added USGS maptype(zoom -2 to 15) after maps.kylemulka.com.
Navigate in USGS map and GEarth simultaneously.
Update Dec16: Zoom and PAN GMaps by mousewheel and keyboard
and have GEarth follow.
Update Dec11: Added the XMaps library (Chris Smoak) to the Demo
for additional features like dashed-arrowheaded polylines etc
todo : Make a Flypath of GPX track with XSLT load the sequence
and let GE fly the path.
Update Dec 11th: Play a track/route in GEarth, pull the points
into the webpage and plot a Polyline in Gmaps, simultaneously!! This is fun!
Todo: Opening Web URL files in GEarth by script.
Update Dec8: Send a play-tour/click-and-zoom/G-force track from
GEarth to webpage and transform it to GPX file/KML file.
Update Dec8: Automatically shot 2 screen images with lat/lon
shift for Stereo Viewing. (click in Gmap and Gearth will take and show stereo images
of that location.
Update dec6: Send a cursored track from GEarth to GMaps and
show Polyline on Gmaps.(shaky)
Update Dec 2: Stereo Viewing in B and W Popup!
Update Dec 2: Create KML datastring in webpage and send it to
GEarth.
Update Dec 2: Create auto-Placemark(KML datastring) in GEarth
for the point clicked in GMaps.
Major Update Dec 1: XSLT transforming a GPX file to a KML string
and express on the fly in GE.
Update Dec1 : Retrieving map downloaprogress for ScreenShot
image timing.
Update Nov 26: Launching and Closing Google Earth from script.
Update Nov 26: Controlling/Animating Latitude, Longitude,
Range, Tilt and Azimuth
Update Nov 26: Making a B and W Screen dump and saving it.
Update Nov 27: Launching the Screen Shot in a IE Popup for
Printing.
Update Nov 27: Sending a GMaps point to GEarth and have a
Fly to with speed setting.
Update Nov 27: Getting real-time cursor lat/lon locations
and saving them.
Update Nov 27: Setting GEarth window size by script
Update Nov 27: Opening local GPX from script.
Update Nov 27: Opening Local KML from script.

Google Maps interface now zooms and pans (on Maps center) with
mousewheel and keyboard while Google Earth follows the movements. (After Kyle Mulka
adde USGS maps working similar to GMaps with GEarth!) Zoom by mousewheel
and plus/minus keys - one level, shift-plus/minus two levels at a time. Panning
is now synched with zoom level. For panning East/West use Left/Right arrows, num
key 4/6, for North/South use Up/Down-arrows or num 8/2 keys. NE numkey 9, SE numkey
3, SW numkey 1 and NW numkey 7. To set a new destination click the
map. The new destination marker is replaced by an animated gif file.
The destination will be send to Google Earth where a Placemark will be created at
that same position(depoending on selection).
Google Earth will fly to the point and takes two Black and White Snapshots which
will be shown in a popup when the GE map has downloaded 100%. Enjoy the flight,
Cybarber!

Take manual Color Stereo 3D Screen dumps in Google Earth with auto Camera base shift
Setup your Google Earth viewport for the first left-side color image. Save image(CTRL-S)
manually under name "tmp998.jpg". If desired, re-set the stereo base factor for
stereo effect(15~30):
. Push the
button to move camera to the right (stereofactor/range). Save second right-side
image manually under name "tmp999.jpg"(CTRL-S). If needed, increase the
%
side-crop for non-overlapping parts. Note: as the compass, copyright notice and
google logo are disturbing the 3D view the bottom 14% is clipped by default
. Compose your image such that the bottom 10-15% is not
relevant so you can safely clip it. Adjust the bottom clip
percentage(%) to hide the logo and compass. Hit
button to view result below.

This is a web application with a Google Earth ActiveX object and
a Google Maps Javascript interface for Internet Explorer.
The page is a bridge between GMaps and GEarth.
This application makes data interchange between the two Google services possible.
Google Earth can be controlled from the page and thus from Google Maps by
using the methods and properties exposed by the GEarth API.
HTML+TIME (SMIL) and VML are used for animation and display.
Please view this page with Internet Explorer 6 or 7
instead of the one you are currently using.
