SAMM
User Manual

9.4.2 Extents
The user may elect to export the visible extent of the mosaic, the entire survey or some user
specified area. If you would like to limit the exported data to the extent of the mosaic window,
set the extent of the mosaic window before opening the export tool.
9.4.3 Resolution
The resolution can be set between 0.1 cm (1 mm) and 1,000 cm (10 m). Because higher
resolution images mean larger file sizes, plan on SAMM taking more time to export images of
higher resolution.
9.4.4 Background color
SAMM allows the user to set the background color of the exported GeoTIFF image to either
transparent or desired color, or to use the background image/chart. GoogleEarth export always
sets the background to transparent.
