Assigning a nearest delivery agent for delivery in a city using neo4j

[Malatesh]

Hello everyone , I am doing  an college project on delivery service in a city, a one of  my use case is to assign a nearest delivery agent for delivery using delivery agent coordinates and order coordinates. I want to implement the above case using neo4j. please help me with that.

if you have the coordinates of each delivery agent and order location, then you can calculate their 'point' value and then calculate the distance between each point. You can iterate over the agents and find the one with the smallest distance.

Here is an example of converting lat/long coordinates to a point type, then calculate the distance between two points. 

with point({latitude: 12.78, longitude: 56.7}) as p1,
point({latitude: -5.248, longitude: 100.0}) as p2
return point.distance(p1,p2) as distance
