Global Mapper User's Manual
• MIN_ELEV (elevation only) - specifies the minimum elevation (meters) to treat as valid when
rendering this layer. Any elevations below this value will be treated as invalid and not be drawn or
exported.
• MAX_ELEV (elevation only) - specifies the maximum elevation (meters) to treat as valid when
rendering this layer. Any elevations above this value will be treated as invalid and not be drawn or
exported.
• CLAMP_ELEVS (elevation only) - if a MIN_ELEV and/or MAX_ELEV value is specified, setting
this to YES will make any valid elevation values outside of the specified range be clamped to the new
range value rather than treated as invalid.
• VOID_ELEV (elevation only) - specifies the elevation (meters) to replace any void areas in the layer
with. If not specified, the void areas will be transparent.
• SHADER_NAME (elevation only) - this sets the name of the shader to use when rendering the
gridded elevation data for this layer. Use this to override use of the shared default shader just for this
layer. This must be one of the names displayed in the shader drop down in Global Mapper, such as
"Atlas Shader" or "Global Shader" or the name of a custom shader.
• TRANSLUCENCY (elevation and raster only) - specifies the level of translucency (i.e. how
"see-through" the layer is). Value values range from 0 to 512, with 0 meaning the layer is completely
transparent (i.e. invisible) and 512 meaning the layer is completely opaque (this is the default).
• IGNORE_ALPHA (raster only) - specifies that an embedded alpha channel in an image should be
ignored. This is useful for images that have incorrect alpha channels. Use IGNORE_ALPHA=YES to
enable.
• BLEND_MODE (elevation and raster only)- specify blend mode to use for combining this overlay
and any previously loaded overlays
♦ NO_BLEND - no blending is done, this is the default
♦ MULTIPLE
♦ SCREEN
♦ OVERLAY
♦ HARD_LIGHT
♦ COLOR_BURN
♦ COLOR_DODGE
♦ DARKEN
♦ LIGHTEN
♦ DIFFERENCE
♦ EXCLUSION
♦ APPLY_COLOR
♦ APPLY_COLOR_REVERSE
♦ KEEP_RED
♦ KEEP_GREEN
♦ KEEP_BLUE
• FEATHER_BLEND_EDGES (raster only) - specifies that the layer should be feature-blended around
one or more ledges. This is a numeric bitfield value. Add the following values to enable blending on
that edge:
♦ 1 - blend top edge
♦ 2 - blend bottom edge
♦ 4 - blend left edge
♦ 8 - blend right edge
For example, to blend all edges, use FEATHER_BLEND_EDGES=15. The
FEATHER_BLEND_SIZE parameter is used to specify how many pixels to blend on each blended
edge.
• FEATHER_BLEND_SIZE (raster only) - specifies the size in pixels to use for a blend boundary.
