Roughness Instructions - rosepearson/GeoFabrics GitHub Wiki
These options control behaviour of the roughness length estimation stage and are all grouped under the roughness
key-value.
The roughness
sub-section can be used to specify advanced settings for the roughness length estimation stage.
parameters
[Optional, dict
] - The parameters applied to the roughness length equation of max(parameter['mean'] * mean, parameter['std'] * std)
.
default_values
[Optional, dict
] - Default values are: {"land": 0.014, "ocean": 0.004, "waterways": 0.004, "rivers": 0.004, "minimum": 0.00001, "maximum": 0.5, "roads": 0.001}
. Currently the road is not supported. In future the plan is to bring in OSM specified roads at specified widths and set to the specified road value. If waterways
, minimum
or maximum
are set to null
/NaN
then the relevant roughness values are left unchanged.
ignore_powerlines
[Optional, bool
] - Not yet implemented. Plan is to support filtering high poiunts (say above a specified height) when this option is included - perhaps as a dictionary in future.
