I have two points as below. I need to get the distance between them in meters.
POINT (80.99456 7.86795)POINT (80.97454 7.872174)How can this be done via GeoPandas?
Best Answer
Your points are in a lon, lat coordinate system (EPSG:4326 or WGS 84). To calculate a distance in meters, you would need to either use the Great-circle distance or project them in a local coordinate system to approximate the distance with a good precision.
For Sri Lanka, you can use EPSG:5234 and in GeoPandas, you can use the distance function between two GeoDataFrames.
from shapely.geometry import Pointimport geopandas as gpdpnt1 = Point(80.99456, 7.86795)pnt2 = Point(80.97454, 7.872174)points_df = gpd.GeoDataFrame({'geometry': [pnt1, pnt2]}, crs='EPSG:4326')points_df = points_df.to_crs('EPSG:5234')points_df2 = points_df.shift() #We shift the dataframe by 1 to align pnt1 with pnt2points_df.distance(points_df2)The result should be 2261.92843 m
