gemgis.vector.calculate_orientations_from_strike_lines

gemgis.vector.calculate_orientations_from_strike_lines(gdf: geopandas.geodataframe.GeoDataFrame) → geopandas.geodataframe.GeoDataFrame

Calculating orientations based on LineStrings representing strike lines

Parameters

gdf (gpd.geodataframe.GeoDataFrame) – GeoDataFrame containing LineStrings representing strike lines

Returns

gdf_orient – GeoDataFrame containing the location of orientation measurements and their associated orientation values

Return type

gpd.geodataframe.GeoDataFrame

New in version 1.0.x.

Changed in version 1.1.7.

Fixing indexing issue.

Example

>>> # Loading Libraries and creating LineString
>>> import gemgis as gg
>>> from shapely.geometry import LineString
>>> import geopandas as gpd
>>> linestring1 = LineString([(0, 0), (20, 20)])
>>> linestring1.wkt
'LINESTRING (0 0, 20 20)'

>>> # Create second LineString
>>> linestring2 = LineString([(0, 10), (20, 30)])
>>> linestring2.wkt
'LINESTRING (0 10, 20 30)'

>>> # Creating GeoDataFrame from LineStrings
>>> gdf = gpd.GeoDataFrame(geometry=[linestring1, linestring2])
>>> gdf['Z'] = [100,200]
>>> gdf['id'] = [1,2]
>>> gdf
    geometry                            Z   id
0       LINESTRING (0.0 0.0, 20.0 20.0)     100 1
1       LINESTRING (0.0 10.0, 20.0 30.0)    200 2

>>> # Calculating orientations strike lines
>>> orientations = gg.vector.calculate_orientations_from_strike_lines(gdf=gdf)
>>> orientations
    dip     azimuth     Z           geometry            polarity        X           Y
0       85.96   135.00  150.00  POINT (10.0 15.0)       1.00        10.00       15.00
