NAME

       osgearth_backfill - specialty tool for post-processing TMS datasets

SYNOPSIS

       osgearth_backfill tms.xml [--bounds xmin ymin xmax ymax | --min-level level | --max-level
                         level | --db-options options]

DESCRIPTION

       osgearth_backfill is a specialty tool that is used to post-process TMS datasets. Some  web
       mapping  services use completely different datasets at different zoom levels. For example,
       they may use NASA BlueMarble imagery until they reach level 4,  then  abruptly  switch  to
       LANDSAT data. This is fine for 2D slippy map visualization but can be visually distracting
       when viewed in 3D because neighboring tiles at different LODs look completely different.

       osgearth_backfill lets  you  generate  a  TMS  dataset  like  you  normally  would  (using
       osgearth_package(1),  or  another  tool) and then "backfill" lower levels of detail from a
       specified higher level of detail. For example, you can specify a max level of 10 and  LODs
       0-9 will be regenerated based on the data found in level 10.

OPTIONS

       tms.xml
              Path to the tms.xml file

       --bounds xmin ymin xmax ymax
              bounds to backfill (in map coordinates; default=entire map)

       --min-level level
              The minimum level to stop backfilling to. (default=0)

       --max-level level
              The level to start backfilling from. (default=inf)

       --db-options options
              db options string to pass to the image writer in quotes (e.g., "JPEG_QUALITY 60")
