geonature.core.imports.checks.dataframe.geometry#

Functions#

get_srid_bounding_box(srid)

Return the local bounding box for a given srid

wkt_to_geometry(value)

xy_to_geometry(x, y)

check_bound(p, bounding_box)

check_geometry_inside_l_areas(geometry, id_area, geom_srid)

Same as check_wkt_inside_l_areas except we use a shapely geometry.

check_wkt_inside_area_id(wkt, id_area, wkt_srid)

Checks if the provided wkt is inside the area defined

check_geometry(df, file_srid, geom_4326_field, ...[, ...])

Module Contents#

geonature.core.imports.checks.dataframe.geometry.get_srid_bounding_box(srid)[source]#

Return the local bounding box for a given srid

geonature.core.imports.checks.dataframe.geometry.xy_to_geometry(x, y)[source]#
geonature.core.imports.checks.dataframe.geometry.check_bound(p, bounding_box: shapely.geometry.Polygon)[source]#
geonature.core.imports.checks.dataframe.geometry.check_geometry_inside_l_areas(geometry: shapely.geometry.base.BaseGeometry, id_area: int, geom_srid: int)[source]#

Same as check_wkt_inside_l_areas except we use a shapely geometry.

geonature.core.imports.checks.dataframe.geometry.check_wkt_inside_area_id(wkt: str, id_area: int, wkt_srid: int)[source]#

Checks if the provided wkt is inside the area defined by id_area.

Parameters#

wktstr

geometry to check if inside the area

id_areaint

id to get the area in ref_geo.l_areas

wkt_sridstr

srid of the provided wkt

geonature.core.imports.checks.dataframe.geometry.check_geometry(df: pandas.DataFrame, file_srid: int, geom_4326_field: geonature.core.imports.models.BibFields, geom_local_field: geonature.core.imports.models.BibFields, wkt_field: geonature.core.imports.models.BibFields = None, latitude_field: geonature.core.imports.models.BibFields = None, longitude_field: geonature.core.imports.models.BibFields = None, codecommune_field: geonature.core.imports.models.BibFields = None, codemaille_field: geonature.core.imports.models.BibFields = None, codedepartement_field: geonature.core.imports.models.BibFields = None, id_area: int = None)[source]#

What this check do: - check there is at least a wkt, a x/y or a code defined for each row

(report NO-GEOM if there are not, or MULTIPLE_ATTACHMENT_TYPE_CODE if several are defined)

  • set geom_local or geom_4326 or both (depending of file_srid) from wkt or x/y - check wkt validity - check x/y validity

  • check wkt & x/y bounding box

What this check does not do (done later in SQL): - set geom_4326 & geom_local from code

  • verify code validity

  • set geom_4326 from geom_local, or reciprocally, depending of file_srid

  • set geom_point

  • check geom validity (ST_IsValid)

FIXME: area from code are never checked in bounding box!
