visibility
Visibility and viewshed analysis.
visibility_graph
Run a visibility graph analysis. This will return three TIFF image files, respectively showing a density, farness, and harmonic closeness based measure.
Parameters
A GeoDataFrame containing building polygons.
A tuple specifying the bounds corresponding to the provided from_crs_code
parameter.
An output path to which the generated TIFF images will be written. The pathname will be appended to correspond to the density, farness, and harmonic closeness measures.
The EPSG coordinate reference code corresponding to the input data.
An output EPSG coordinate reference code. None
by default, in which case a UTM projection will be used.
The view distance within which to run the visibility analysis. 100m by default.
The spatial resolution in metres to use when generating the raster. Lower resolutions will result in faster analysis.
visibility_graph_from_osm
Retrieves OSM buildings for the specified WGS bounds and runs a visibility analysis. This will return three TIFF image files, respectively showing a density, farness, and harmonic closeness based measure.
Parameters
A tuple specifying the bounds corresponding to the provided from_crs_code
parameter.
An output path to which the generated TIFF images will be written. The pathname will be appended to correspond to the density, farness, and harmonic closeness measures.
An output EPSG coordinate reference code. None
by default, in which case a UTM projection will be used.
The view distance within which to run the visibility analysis. 100m by default.
The spatial resolution in metres to use when generating the raster. Lower resolutions will result in faster analysis.
viewshed
Run a viewshed analysis from a specified point. Writes an output image to the specified output path.
Parameters
A GeoDataFrame containing building polygons.
A tuple specifying the bounds corresponding to the provided from_crs_code
parameter.
An easting or longitude for the origin of the viewshed in the from_crs_code
coordinate reference system.
A northing or latitude for the origin of the viewshed in the from_crs_code
coordinate reference system.
An output path to which the generated TIFF images will be written. The pathname will be appended to correspond to the density, farness, and harmonic closeness measures.
The EPSG coordinate reference code corresponding to the input data.
An output EPSG coordinate reference code. None
by default, in which case a UTM projection will be used.
The view distance within which to run the visibility analysis. 100m by default.
The spatial resolution in metres to use when generating the raster. Lower resolutions will result in faster analysis.
viewshed_from_osm
Run a viewshed analysis from a specified point using OSM data. Writes an output image to the specified output path.
Parameters
A tuple specifying the bounds corresponding to the provided from_crs_code
parameter.
A longitude for the origin of the viewshed in WGS84 coordinates.
A latitude for the origin of the viewshed in WGS84 coordinates.
An output path to which the generated TIFF images will be written. The pathname will be appended to correspond to the density, farness, and harmonic closeness measures.
An output EPSG coordinate reference code. None
by default, in which case a UTM projection will be used.
The view distance within which to run the visibility analysis. 100m by default.
The spatial resolution in metres to use when generating the raster. Lower resolutions will result in faster analysis.
