wolfhece.picc.adding_layer_to_zone(fn: pathlib.Path, bbox: shapely.geometry.Polygon = None, ZonesPicc: wolfhece.PyVertexvectors.Zones = None)

Add other layers informations to the picc zones ! Need GEOREF_ID as principal “name” of the zone !

class wolfhece.picc.Picc_data(idx: str = '', plotted: bool = True, mapviewer=None, need_for_wx: bool = False, data_dir: pathlib.Path = Path('./data/PICC'), bbox: shapely.geometry.Polygon | list[float] = None, filename_vector: str = 'PICC_Vesdre.shp', filename_point: str = 'PICC_Vesdre_points.shp')

Bases: wolfhece.drawing_obj.Element_To_Draw

Read and show PICC data – see https://geoportail.wallonie.be/georeferentiel/PICC

read_data(data_dir: pathlib.Path = None, bbox: shapely.geometry.Polygon | list[float] = None, colorize: bool = True) → None

Read data from PICC directory

Parameters:

• data_dir – directory where PICC data are stored

• bbox – bounding box to select data

read_vectors_cloud_picc(data_dir: pathlib.Path = None, path_vector: str = 'PICC_Vesdre.shp', path_points: str = 'PICC_Vesdre_points.shp', bbox: shapely.geometry.Polygon | list[float] = None, column: str = 'GEOREF_ID', additional_layers: bool = None) → None

Complete reading of the PICC files : vectors (.shp) and clouds (.shp). For the vectors, read any attributes that exist, a priori : [‘NATUR_CODE’, ‘NATUR_DESC’, ‘PRECIS_XY’, ‘PRECIS_Z’, ‘TECH_LEVE’,’DATE_LEVE’, ‘DATE_CREAT’, ‘DATE_MODIF’, ‘DATE_TRANS’, ‘CODE_WALTO’] Pay attention, this uses directly Zone() but may be slow for a large raster. Use “create_zone_picc”

filter_by_name(path_vector: str, path_points: str, name: str = 'Habitation', bbox: shapely.geometry.Polygon | list[float] = None)

Filter the PICC by a name of ‘NATUR_DESC’ attribute, and only keeps properties [‘GEOREF_ID’, ‘NATUR_CODE’, ‘NATUR_DESC’]

create_zone_picc(path_vector: str = 'PICC_Vesdre.shp', path_points: str = 'PICC_Vesdre_points.shp', name: str = 'Habitation', bbox: shapely.geometry.Polygon | list[float] = None, column: str = 'GEOREF_ID')

Complete reading of the PICC files : vectors (.shp) and clouds (.shp). For the vectors, read any attributes that exist, among [‘NATUR_CODE’, ‘NATUR_DESC’, ‘PRECIS_XY’, ‘PRECIS_Z’, ‘TECH_LEVE’,’DATE_LEVE’, ‘DATE_CREAT’, ‘DATE_MODIF’, ‘DATE_TRANS’, ‘CODE_WALTO’] For now, path_points not used but may be useful later

plot(sx=None, sy=None, xmin=None, ymin=None, xmax=None, ymax=None, size=None)

Plot data in OpenGL context

Parameters:

• sx – x scaling factor

• sy – y scaling factor

• xmin – minimum x value

• ymin – minimum y value

• xmax – maximum x value

• ymax – maximum y value

• size – size of the points

check_plot()

Generic function responding to check operation from mapviewer

uncheck_plot(unload: bool = True, reset_filename: bool = False)

Generic function responding to uncheck operation from mapviewer

show_properties()

Showing properties of the object

Active_vector(vector_to_activate: wolfhece.PyVertexvectors.vector)

Activate a vector

Active_zone(zone_to_activate: wolfhece.PyVertexvectors.zone)

Activate a zone

extrude_polygons(dest_array)

Extrude the active polygon along the z-axis

class wolfhece.picc.Cadaster_data(idx: str = '', plotted: bool = True, mapviewer=None, need_for_wx: bool = False, data_dir: pathlib.Path = Path('./data/Cadastre'), bbox: shapely.geometry.Polygon | list[float] = None)

Bases: Picc_data

Read and show cadaster data

_filename_vector = 'Cadastre.shp'

_filename_points = ''

read_data(data_dir: pathlib.Path = None, bbox: shapely.geometry.Polygon | List[float] = None, colorize: bool = True) → None

Read data from PICC directory

Parameters:

• data_dir – directory where PICC data are stored

• bbox – bounding box to select data
