I have extracted co-ordinates data from Twitter. The points I got are in the WKT format. I want to split them into two columns of Latitude and Longitude. The format of the coordinates is
{'type': 'Point', 'coordinates': [77.58168, 12.8952]}
{'type': 'Point', 'coordinates': [77.64363, 12.9739]}
{'type': 'Point', 'coordinates': [75.9372318, 12.44627712]}
{'type': 'Point', 'coordinates': [77.5945627, 12.9715987]}
{'type': 'Point', 'coordinates': [77.53584257, 13.05144109]}
{'type': 'Point', 'coordinates': [77.5945627, 12.9715987]}
{'type': 'Point', 'coordinates': [77.58721, 12.96643]}
I removed all the punctuations and unwanted text using str.replace
df['coordinates'] = df.coordinates.str.replace('type,?' , '')
df['coordinates'] = df.coordinates.str.replace('Point,?' , '')
df['coordinates'] = df.coordinates.str.replace('coordinates,?' , '')
df['coordinates'] = df.coordinates.str.replace('{,?' , '')
df['coordinates'] = df.coordinates.str.replace(',,?' , '')
df['coordinates'] = df.coordinates.str.replace(':,?' , '')
df['coordinates'] = df.coordinates.str.replace('],?' , '')
df['coordinates'] = df.coordinates.str.replace(',?' , '')
df['coordinates'] = df.coordinates.str.replace('},?' , '')
df['coordinates'] = df.coordinates.str.replace("'',?" , "")
I tried to split the column using
df = pd.DataFrame(df.coordinates.str.split(' ',1).tolist(),
columns = ['Long','Lat'])
But it's not working. Please let me know what can be done to convert WKT to Columns of Co-ordinates
The geopandas
docs covers importing data in WKT format using shapely
. In their example, given your dataframe df
, you could try:
from shapely import wkt
import geopandas as gpd
df['coordinates'] = df['coordinates'].apply(wkt.loads)
gdf = gpd.GeoDataFrame(df, geometry='coordinates')
If you want, you can get the latitude and longtitude and assign back to your original dataframe by doing the following.
df['lat'] = gdf.geometry.x
df['long'] = gdf.geometry.y
Since you didn't provide a complete minimum working example, I haven't tested this code, but I think it should work.
