Inner Drive Extensible Architeture
The Inner Drive Extensible Architecture implements common .NET development situations including time zones, money, measurements and conversions, and Microsoft Azure features.
InnerDrive.Geography
Features
- Includes fundamental geography concepts as first-class structures
- Simple methods for calculating distance and direction between geographical points
- Astronomy classes to predict sun and moon events
Prerequisites
This package runs on .NET 10. It depends on these packages:
Usage
Find the distance and bearing between two points:
// 40°42'47"N 74°00'47"W, 11.0 m
var origin = new Node(
new Latitude(40d, 42d, 47d),
new Longitude(-74d, 0d, 47d),
11d.Meters()
);
// 41°52'44"N 87°38'09"W, 181.0 m
var destination = new Node(
new Latitude(41d, 52d, 44d),
new Longitude(-87d, 38d, 9d),
181d.Meters()
);
var distance = origin.Distance(destination);
var bearing = origin.Bearing(destination);
// Google Earth says 1,147,086 m
var refDistance = 1147068d.Meters();
var accuracy = distance.Accuracy; // Distance is about 99.5% accurate over longer ranges because the calculation assumes a spherical earth
Trace.WriteLine($"From {origin} to {destination} is {distance.ToString("0,0.000", MetricExponent.Kilo)}");
Trace.WriteLine($"(accuracy {accuracy.ToString("0.000", MetricExponent.Kilo)}; reference distance {refDistance.ToString("0,0.0", MetricExponent.Kilo, CultureInfo.InvariantCulture)})");
Output > From 40.71305°N, 74.01305°W, 11 m to 41.87889°N, 87.63583°W, 181 m is 1,143.566 km at 280.97528°
(accuracy 5.718 km; reference distance 1,147.1 km)
The Inner Drive Technology website has a full SDK and example code. We also have a demo weather site that uses all the IDEA components.
