r.green.hydro.delplants - Delete segments where there is an existing plant

KEYWORDS

SYNOPSIS

r.green.hydro.delplants

r.green.hydro.delplants --help

r.green.hydro.delplants [-d] hydro=name [hydro_layer=string] river=name output_streams=string [output_plants=string] [hydro_kind_intake=string] [hydro_kind_turbine=string] elevation=name [other=name] [other_layer=name] [other_kind_intake=string] [other_kind_turbine=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-d: Debug with intermediate maps
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

hydro=name [required]: Name of the vector map with the points (intake and restitution) of hydropower plants; Or data source for direct OGR access
hydro_layer=string: Name of the vector map layer of the hydropower plants, with the following attributes: kind_label (intake/restitution), discharge [m3/s], id_point, id_plant; Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name.; Default: 1
river=name [required]: Name of the vector map with the streams; Or data source for direct OGR access
output_streams=string [required]: Name of the vector map with the stream segments without plants
output_plants=string: Name of the vector map with the stream segments of the existing plants
hydro_kind_intake=string: Value contained in the column kind_label that indicates the plant is an intake; Default: intake
hydro_kind_turbine=string: Value contained in the column kind_label that indicates the plant is a restitution; Default: restitution
elevation=name [required]: Name of input elevation raster map
other=name: Name of the vector map with points (intake and restitution) of other plants such as irrigation, acqueducts, etc.; Or data source for direct OGR access
other_layer=name: Name of the vector map layer of other plants, with the following attributes: kind_label (intake/restitution), discharge [m3/s], id_point, id_plant; Or data source for direct OGR access; Default: 1
other_kind_intake=string: Value contained in the column kind_label that indicates the plant is an intake; Default: intake
other_kind_turbine=string: Value contained in the column kind_label that indicates the plant is a restitution; Default: restitution

DESCRIPTION

r.green.hydro.delplants deletes segments of river where there is an existing plant.

NOTES

This command is used to select the segments of river which are not already exploited by a plant or another structure.
The required inputs are the elevation raster map, the map with the streams and the one with the intakes and restitution of the existing plants. In option, it is possible to add the map with the intakes and restitution of the other structures such aqueducts or irrigation in order to delete these segments too.
It is necessary to verify in "Optional" that the intakes and restitution are well reported in the table of the input maps (hydro and other).

EXAMPLE

This example is based on the case-study of Mis valley in Belluno province, Veneto, Italy.

input

Input vector maps : streams of Mis Valley in black and intakes and restitution of existing plants in red

We use the following code to compute the available streams and obtain the next map :

r.green.hydro.delplants hydro=existingplants river=streams output=availablestreams elevation=elevation

d.vect map=existingplants color=red

Output vector map in black : streams of Mis Valley without the existing plants (intakes and restitution of existing plants are added there in red)
