Global Mapper User's Manual
♦ NTF_GRID - a NTF grid format file.
♦ OPTIMI_GRID - an Optimi terrain or clutter grid format file.
♦ OZI - an OziExplorer format waypoint (WPT) or track (PLT) file.
♦ PCX - a PC Paintbrush PCX format file.
♦ PCX5 - a Garmin PCX5 format waypoint (WPT) or track (TRK) file.
♦ ROCKWORKS_GRID - a RockWorks Grid format file.
♦ RPF - Raster Product Format database, like CADRG.
♦ RPF_FRAME - single frame from a Raster Product Format database, like CADRG.
♦ S57 - a S-57 chart file
♦ SDTS - a SDTS transfer
♦ SEGP1 - a SEGP1 seismic shotpoint file.
♦ SHAPEFILE - an ESRI Shapefile.
♦ SURFERGRID - a Surfer grid format file.
♦ SWEDISHDEMGRID - a Swedish DEM grid format file.
♦ TERRASCAN - a TerraScan LIDAR format file.
♦ TIGER_LINE - a Tiger/Line format file.
♦ USGS_DEM - a native format USGS DEM file.
♦ VPF - a Vector Product Format file such as VMAP or DNC data
♦ VULCAN_3D - a Vulcan3D triangulation file
♦ ZMAP_PLUS - a Geographix Zmap Plus+ format file.
• PROMPT_IF_TYPE_UNKNOWN - set to NO if you don't want the user to be prompted to select a
file type if the type cannot automatically be determined (useful when looping).
• HIDDEN - set to YES to cause this overlay to be hidden from view after it is loaded. The default is to
show the overlay.
• SAMPLING_METHOD (elevation and raster only) - specifies the sampling method to use when
resampling this layer. The following values are supported:
♦ NEAREST_NEIGHBOR - use the nearest neighbor sampling method
♦ BILINEAR - use bilinear interpolation
♦ BICUBIC - use bicubic interpolation
♦ BOX_3X3 - use a 3x3 box average
♦ BOX_4X4 - use a 4x4 box average
♦ BOX_5X5 - use a 5x5 box average
♦ BOX_7X7 - use a 7x7 box average
♦ BOX_9X9 - use a 9x9 box average
♦ MAX_3X3 - (terrain layers only) use maximum value found in 3x3 box
♦ MAX_4X4 - (terrain layers only) use maximum value found in 4x4 box
♦ MAX_5X5 - (terrain layers only) use maximum value found in 5x5 box
♦ MAX_7X7 - (terrain layers only) use maximum value found in 7x7 box
♦ MAX_9X9 - (terrain layers only) use maximum value found in 9x9 box
• ANTI_ALIAS [DEPRECATED - use SAMPLING_METHOD instead] (elevation and raster only) -
specifies whether to remove jagged edges by making a subtle transition between pixels. Turning off
this option helps maintain the hard edges of the pixels as they are rasterized. Use ANTI_ALIAS=YES
to turn on. Anything else turns it off.
• CONTRAST_MODE (raster only) - specifies the type of contrast adjustment to apply to the data.
♦ NONE - no contrast adjustment applied (this is the default)
♦ PERCENTAGE - apply a percentage contrast adjustment. The
CONTRAST_STRETCH_SIZE parameter can be used to override the number of standard
deviations from the mean to stretch to.
♦ MIN_MAX - apply a min/max contrast stretch, stretching the available range of values in
each color band to the full range of 0-255. For imagery which contains both black and white,
this will have no affect.
