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
