[Therion] Google Earth terrain model

[thomasschilter at bluewin.ch]

Hello
Does anyone with a Windows machine? Did someone perhaps the Google Earth script by Martin reprogrammed? Or what other 
options there are? Unfortunately I have no idea about the program. 

Best regards
Thomas

This one is for AppleScript and for map data.

There is a trick - you must mimic the human interaction to save the  
image. If by script it will be only grey.

GoogleEarth:

1. change the units to UTM
2. switch off the terrain, and all features which occupy the screen  
and which is possibly to take off.
2. put in the corners of area placemarks the best are white crosses.  
You may go very near - several meters from surface, so you may put  
the cross exactly.
3. change the units to degrees and take a note the coordinates of  
upper left and lower right crosses. Reason is the script doesn't  
recognize the UTM coordinates.
4. modify script according your coordinates - the coordinates of  
start point for row and for column, the step for row and for column  
(don't forget the overlay), the end point fot row and for collumn.  
The altitude of camera 2000 m is quite enough.
5. manually save one image to forder you want to all images will be  
saved. Delete it.
6. start the script.
7. you should receive the full folder of images numbered according  
rows/collumns.

Photoshop (CS3 and more):

1. record the action to crop of first image to remove all rests of  
logos from image.
2. make the dropplet from that action.
3. drag all uncropped images to this dropplet.
4. make a panorama from first row in Brigde application - just to  
change place, no any deformations. No blending!. Save it with  
suitable name.
5. do the same with another rows.
6. open the middle row and row just below it. Change the size of  
camvas of middle row to assumed size of map.
7. move the second row to canvas (it will create new layer and resize  
the second row so it is exactly wide as first one.
8. set the behaviour of second layer to "Difference" and manualy move  
so as the overlay will be as black as possible :). switch the  
behaviour to Normal,
9. Do the same with all rows bellow and with all rows above the  
middle row. You may flat the layers time from time to decrease the  
size of final map and save it after each row added.
10. resize the image unproportionaly so the distance of crosses  
horizontally and vertically is in scale you want.
11. crop the map in crosses.
12. you may add white lines after each km/mile and coordinates too.

Altitude:

as in first case, but with Tterrain on and the script will read the  
altitude of placemark in the middle of screen. You should use the  
same trick with UTM and degrees.

m.s.

Map script for Applescript:

-- coordinates of left upper corner of area (degrees)
property beginning_lat : 41.764341
property beginning_long : 21.321398 (*41.764341 21.321398*)

-- parameters for GoogleEarth
set myAltitude to 2000
set myTilt to 0
set myAzimuth to 0

-- parameters for file names
property N : 0
property M : 0

-- parameters for end of script (degrees)

property mySouth : 41.72
property myEast : 21.4
property long_step : 0.0062
property lat_step : 0.0025

set myLat to beginning_lat
set myLong to beginning_long

repeat while myLat ≥ mySouth -- last row, where script stops
	
	set N to N + 1
	
	repeat while myLong ≤ myEast -- end of row and beginning of next one
		
		set M to M + 1

				end tell
			end if
		end tell
		set myLong to (myLong + long_step) -- long step - it depends on  
size of screen. There  should be  10-15% overlap of images
		
	end repeat
	set myLong to beginning_long -- return to beginning of row
	set M to 0
	set myLat to (myLat - lat_step) -- lat step there should be 10-15%  
overlap
end repeat
