The nearest distance between the point and the polygon, regardless of point's position, is: t.boundary.distance(t2). Before calculating distance, covert your GeoDataFrame to a Cartesian projection. 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. It only takes a minute to sign up. The operation works on a 1-to-1 row-wise manner: I've used a quick-and-dirty GeoPandas apply: df ['subset_distance'] = df.geometry.apply (lambda g: df_subset.distance (g).min ()) which works, but it's pretty slow, even on my test dataset of around 700 polygons.
