Distances Calculation API vs Proximity Calculation API: What to Choose?

When it comes to geospatial applications, developers often face the challenge of choosing the right API for distance calculations. Two popular options are the Distances Calculation API and the Proximity Calculation API. Each of these APIs offers unique features and capabilities that cater to different use cases. In this blog post, we will delve into a detailed comparison of these two APIs, exploring their functionalities, performance, and ideal scenarios for use.

Overview of Both APIs

The Distances Calculation API is designed to calculate travel distances and durations between an origin and multiple destinations. This API is particularly useful for applications that require route planning, logistics management, and travel itinerary creation. By providing essential information about distances and travel times, it enables users to make informed decisions about their routes.

On the other hand, the Proximity Calculation API focuses on precise geospatial distance calculations, making it ideal for applications in logistics, navigation, marketing, and spatial analysis. This API utilizes advanced geospatial algorithms to measure distances between geographic points defined by latitude and longitude coordinates, allowing for complex distance scenarios, including routes with multiple waypoints.

Feature Comparison

Distances Calculation API Features

The Distances Calculation API offers several key features:

Distance Calculator

This feature allows users to specify a source and one or more destinations in the parameters. Upon making a request, the API returns a structured response containing detailed information about each trip.

{
   "destination_addresses" : [
      "7 E 54th St, New York, NY 10022, USA",
      "34 St-Herald Sq, New York, NY 10001, USA"
   ],
   "origin_addresses" : [
      "569 Vermont St, Brooklyn, NY 11207, USA"
   ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "28.4 km",
                  "value" : 28415
               },
               "duration" : {
                  "text" : "42 mins",
                  "value" : 2493
               },
               "status" : "OK"
            },
            {
               "distance" : {
                  "text" : "27.4 km",
                  "value" : 27384
               },
               "duration" : {
                  "text" : "38 mins",
                  "value" : 2251
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

In this response, the destination_addresses field lists the queried destinations, while the origin_addresses field shows the starting point. The rows array contains elements that provide the distance and duration for each destination. The distance object includes both textual and numeric representations, which are useful for display and computational purposes.

dsdsDistance Calculator

This feature is similar to the Distance Calculator, requiring users to specify a source and one or more destinations. However, it may return a status indicating that a destination was not found.

{
   "destination_addresses" : [""],
   "origin_addresses" : [""],
   "rows" : [
      {
         "elements" : [
            {
               "status" : "NOT_FOUND"
            }
         ]
      }
   ],
   "status" : "OK"
}

This response indicates that the API was unable to find the specified destination. The status field provides feedback on the request's success, which is crucial for error handling in applications.

Proximity Calculation API Features

The Proximity Calculation API also has significant features:

Measuring Distance

This feature allows users to calculate the distance between two geographic points by providing their latitude and longitude coordinates. The API returns a structured response with precise distance measurements.

{
   "statusCode": 200,
   "body": {
      "distance": {
         "meters": 189.7602141814502,
         "kilometers": 0.1897602141814502,
         "miles": 0.1179118235931812
      }
   }
}

The response includes a statusCode indicating the success of the request, and the body contains a distance object with measurements in meters, kilometers, and miles. This flexibility allows developers to choose the most appropriate unit for their applications.
