gemgis.vector.extract_xy_points(gdf: geopandas.geodataframe.GeoDataFrame, reset_index: bool = True, drop_id: bool = True, drop_index: bool = True, overwrite_xy: bool = False, target_crs: Union[str, pyproj.crs.crs.CRS] = None, bbox: Optional[Sequence[float]] = None) → geopandas.geodataframe.GeoDataFrame#

Extracting X and Y coordinates from a GeoDataFrame (Points) and returning a GeoDataFrame with X and Y coordinates as additional columns

Parameters

  • gdf (gpd.geodataframe.GeoDataFrame) – GeoDataFrame created from vector data containing elements of geom_type Point

  • reset_index (bool) – Variable to reset the index of the resulting GeoDataFrame. Options include: True or False, default set to True

  • drop_id (bool) – Variable to drop the id column. Options include: True or False, default set to True

  • drop_index (bool) – Variable to drop the index column. Options include: True or False, default set to True

  • overwrite_xy (bool) – Variable to overwrite existing X and Y values. Options include: True or False, default set to False

  • target_crs (Union[str, pyproj.crs.crs.CRS]) – Name of the CRS provided to reproject coordinates of the GeoDataFrame, e.g. target_crs='EPSG:4647'

  • bbox (list) – Values (minx, maxx, miny, maxy) to limit the extent of the data, e.g. bbox=[0, 972, 0, 1069]

Returns

gdf – GeoDataFrame with appended X and Y coordinates as new columns and optional columns

Return type

gpd.geodataframe.GeoDataFrame

New in version 1.0.x.
