COMPARE_STR="CFCC=A*" as your parameter. You can add multiple COMPARE_STR
parameters to a single command to combine multiple criteria for your search. If you would like to
compare against a feature label rather than an attribute, use for your attribute name.
To compare against a feature type name rather than an attribute, use for your attribute
name. To compare against the feature description, use for your attribute name.
• CASE_SENSITIVE - specifies whether or not text comparisons are case sensitive or not. Use
CASE_SENSITIVE=YES to enable, by default comparisons are not case sensitive.
GENERATE_WATERSHED
Global Mapper User's Manual
The GENERATE_WATERSHED command allows for the generation of a watershed, including stream flow
and optionally watershed areas for each stream segment. The following parameters are supported by the
command.
• STREAM_THRESHOLD - specifies the number of cells that have to drain to a particular location
before that location is considered to be part of the stream network.
• MAX_DEPTH - specifies the maximum depression depth (in meters) that will be filled prior to
calculating the watershed. This is needed to prepare a terrain surface for flow analysis so that a
continuous flow can be found. Note that while using a large MAX_DEPTH value may generate better
results, it could also cause the process to take a lot longer.
• GEN_AREAS - generate watershed area features for each found stream segment outlining the area
that drains into that stream. Enabled by default, use GEN_AREAS=NO to disable.
• SMOOTH_STREAMS - specifies whether or not generated streams should have smoothing applied to
improve appearance. This option is enabled by default. Use SMOOTH_STREAMS=NO to disable
smoothing.
• SPATIAL_RES - specifies spacing of grid points used to calculate the watershed. A smaller grid
spacing results in higher fidelity, but the calculation process will take longer. Typically you'll want to
use the default value which is the minimum spatial resolution of all loaded data. Should be formatted
as x_resolution,y_resolution. The units are the units of the current global projection. For example, if
UTM was the current global projection and you wanted to use a grid with a 30 meter spacing, the
parameter/value pair would look like SPATIAL_RES=30.0,30.0.
• SPATIAL_RES_METERS - specifies spatial resolution to use in meters. The value in meters will
automatically be converted to the curent view/export projection units. For example, to do an export at
2.0 meter spacing (or as close as you can get to that in the current units), use
SPATIAL_RES_METERS=2.0, or to do an export at 1.0 meters in X by 1.5 meters in Y, use
SPATIAL_RES_METERS="1.0,1.5".
• GLOBAL_BOUNDS - specifies the contour bounds in units of the current global projection. There
should be 4 values in a comma-delimited list following the parameter name. The values should be in
order of minimum x, minimum y, maximum x, maximum y.
• GLOBAL_BOUNDS_SIZE - specifies the contour bounds in units of the current global projection.
There should be 4 values in a comma-delimited list following the parameter name. The values should
be in order of minimum x, minimum y, width in x, width in y.
• LAT_LON_BOUNDS - specifies the contour bounds in latitude/longitude degrees. There should be 4
values in a comma-delimited list following the parameter name. The values should be in order of
westmost longitude, southernmost latitude, easternmost longitude, northernmost latitude.
• LAYER_BOUNDS - specifies that the contour generation should use the bounds of the loaded
layer(s) with the given filename. For example, to generate contours to the bounds of the file
"c:\test.tif", you would use LAYER_BOUNDS="c:\test.tif". Keep in mind that the file must be
currently loaded.
