Example BeanShell map sources

Mars

/*
 Tile script for mars maps (see http://www.uahirise.org/releases/hiwish.php for details)
 May not be very useful for most users but you can at least fetch a large texture from mars...
 reverse engineered with FireBug and TAC Map Evaluator 1.7 beta 8 by Henry T.

 You can choose between 3 different layers (infrared, visible, elevation)

 They use the google technology with some recursive quadtree naming convention for the tiles resulting in longer
 filenames the more you zoom in. Therefore I use a recursive function.
 
 top left: "q"
 top right: "r" 
 bottom right: "s"
 bottom left: "t"
 Heres an example for a 2x2 map (zoom=1)
 [ q  r ]
 [ t  s ]

 Heres an example for a 4x4 map (zoom=2)
 [ qq  qr  rq  rr ]  
 [ qt  qs  rt  rs ]
 [ tq  tr  sq  sr ]
 [ tt  ts  st  ss ]
*/

 tileType = "jpg";
 int w, z0;   // store the map width and zoom level 
 String[] Table = { "q", "r", "t", "s" };

// recursive function for character concatenation
// maybe not too fast but a bit easier to understand
String BuildTileName(int z, int x, int y)
  {
  if(z==0) return "";	

  int w1 = w>>(z0-z);    
  int x1 = ((x%w1)<<1)/w1;
  int y1 = ((y%w1)<<1)/w1;

  String s = Table[(y1<<1) + x1];
  return s + BuildTileName(z-1, x, y);
  }

String getTileUrl( int zoom, int x, int y ) 
  {
  baseUrl = "http://mw1.google.com/mw-planetary/mars/"; 

/* you choose */
  MapType = "infrared";
//  MapType = "visible";
//  MapType = "elevation";
  w = 1<<zoom;
  z0 = zoom;
 
  return baseUrl + MapType + "/t" + BuildTileName(zoom, x, y) + ".jpg";    
}
