Space with a (pseudo-)metric allows us to perform distances. This library offers several functionalities in this regard;
How to install
================
We run the command on desired installation environment:
``` {.bash}
pip install spycio
```
Minimal example
================
``` {.bash}
#!/usr/bin/env python
from numpy import pi, Inf
from spycio import distance, travelTime
from spycio.utils import spherToGeo
def format_distance_without_configuration(A, B, speed, method):
string_template='A:{origin}, B:{target}, speed:{speed}, method:{on}, distance:{d}, eta:{eta}'
dist=distance(A, B, method)
duration=travelTime(speed, A, B, method)
return string_template.format(origin=A,target=B,speed=speed, on=method,d=dist,eta=duration)
def format_distance(A, B, speed, method, config):
string_template='A:{origin}, B:{target}, speed:{speed}, method:{on}, config:{setup}, distance:{d}, eta:{eta}'
dist=distance(A, B, method, config)
duration=travelTime(speed, A, B, method, config)
return string_template.format(origin=A,target=B, speed=speed, on=method,setup=config, d=dist, eta=duration)
# Default distance calculation: Euclidean
