Module to operate with HERETile tiling scheme using (Geo)DataFrames.

here.geopandas_adapter.geotiles.heretile.ancestor(tile_ids: Series, level: int | None = None) → Series[source]#

Return the ancestor tiles at the given level for the tiles.

Index and NaN values are retained. NaN is also returned in case of invalid tile IDs or tiling level, or when the ancestor doesn’t exist.

Parameters:

  • tile_ids – the tile IDs

  • level – the tiling level

Returns:

a pd.Series with the tile IDs of the ancestors or parents, when existing

Raises:

ValueError – in case the series doesn’t contain integers # noqa

here.geopandas_adapter.geotiles.heretile.contains_coordinates(tile_ids: Series, lngs: Series, lats: Series) → Series[source]#

Return if the tiles contains the points.

The check includes the tile boundary, aligned with the way shapely intersects operates.

NaN values or not all the series containing a value for a given index determine the resulting tile ID to be NaN.

Parameters:

  • tile_ids – the tile IDs

  • lngs – the Series with longitudes

  • lats – the Series with latitudes

Returns:

a pd.Series containing if the points are inside the tiles

Raises:

ValueError – in case the series doesn’t contain integers # noqa

here.geopandas_adapter.geotiles.heretile.contains_geometry(tile_ids: Series, geometries: GeoSeries, fully_contained=False) → Series[source]#

Return if the tiles contain the geometries.

Inclusion is modeled as the shapely relation intersects (fully_contained is false) or contains (otherwise) between the tile and the geometry.

NaN values or not all the series containing a value for a given index determine the resulting tile ID to be NaN.

Parameters:

  • tile_ids – the tile IDs

  • geometries – a ``gpd.GeoSeries` with any geometric type

  • fully_contained – check if each geometry is fully contained in each tile

Returns:

a pd.Series of booleans, if the geometries are inside the tiles

Raises:

ValueError – in case the series doesn’t contain integers # noqa

here.geopandas_adapter.geotiles.heretile.contains_point(tile_ids: Series, pts: GeoSeries) → Series[source]#

Return if the tiles contains the points.

This method is more efficient than contains_geometry for points.

The check includes the tile boundary, aligned with the way shapely intersects operates.

NaN values or not all the series containing a value for a given index determine the resulting tile ID to be NaN.

Parameters:

  • tile_ids – the tile IDs

  • pts – the ``gpd.GeoSeries` with points

Returns:

a pd.Series of booleans, if the points are inside the tiles

Raises:

ValueError – in case the series doesn’t contain integers # noqa

here.geopandas_adapter.geotiles.heretile.descendants(tile_ids: Series, level: int | None = None) → Series[source]#

Return the tile IDs of all descendants at some level for each tile.

Index and NaN values are retained. NaN is also returned in place of empty lists or in case of invalid tile IDs or tiling level.

Use pd.Series.explode method to turn the lists into multiple rows.

Parameters:

  • tile_ids – the tile IDs

  • level – the tiling level

Returns:

a pd.Series with the list of descendants tile IDs for each tile

Raises:

ValueError – in case the series doesn’t contain integers # noqa

here.geopandas_adapter.geotiles.heretile.from_coordinates(lngs: Series, lats: Series, level: int) → Series[source]#

Return the tiles that contain points.

Series must be indexed the same. NaN values or series missing a row for some index value determine the resulting tile ID to be NaN. This is also the case if a point can’t be mapped to a tile ID.

  • level – the tiling level

Returns:

a Series tile IDs, NaN when no tile ID can be calculated

here.geopandas_adapter.geotiles.heretile.from_point(pts: GeoSeries, level: int) → Series[source]#

Return the tiles that contain points.

NaN values or rows not containing a Point determine the resulting tile ID to be NaN. This is also the case if a point can’t be mapped to a tile ID.

Index is retained.

Parameters:

  • pts – the GeoSeries with the points

  • level – the tiling level

Returns:

a Series tile IDs, NaN when no tile ID can be calculated

here.geopandas_adapter.geotiles.heretile.from_x_y_level(xs: Series, ys: Series, levels: Series) → Series[source]#

Series must be indexed the same. NaN values or series missing a row for some index value determine the resulting tile ID to be NaN. This is also the case if not tile ID corresponds to a (x, y, level) tuple.

Index is retained.

Parameters:

  • xs – the Series with the tile X component

  • ys – the Series with the tile Y component

  • levels – the Series with tile levels
