To be efficiently served by mapserver, the Landsat
raster data should be reprojected to the
WGS84/World_Mercator coordinate
system and the "osm" vector data converted into
tiled/indexed shapefile.
This is basic GIS stuff.
It seems that the people running OSM project reject
everything GIS-related, and insist on using XML.
Even when it does not make sense and requires 12GB RAM

for parsing alone (i have tried it on a 32GB RAM
machine with the latest planet-2006*.osm file).
