It crops the image to the area of map + header + border around them. You may 
increase the border by setting 'overlap' in the layout.

You may hide header (north arrow etc.) using 'map-header 100 100 off' option 
in layout.

You may switch station marks off using 'symbol-hide point station' in layout 
without the need of metapost redefinitions.

If you want to display cave in the scale 1:1000 with the topographical map as 
a background, try cropping the bitmap to an area slightly larger than the 
cave; or use SVG.
