GeoSpatial4Net

.NET core library with basic geospatial operations such as distance calculation or conversion. Feel free to reach out if operations are missing or better, do a pull request!

Install

This library is available on nuget. To install it via the package manager: PM> Install-Package GeoSpatial4Net

Quick start

Distance calculation

Compute the distance (in meters by default) between two coordinates using the Haversine formula:

var coord1 = new Coordinate(36.12, -86.67);
var coord2 = new Coordinate(33.94, -118.4);
var distCalc = new GeoDistanceCalculator();
var computedDistance = distCalc.HaversineDistance(coord1, coord2);

You can also call the method directly with the 2 points' latitude/longitude:

var distCalc = new GeoDistanceCalculator();
var computedDistance2 = distCalc.HaversineDistance(36.12, -86.67, 33.94, -118.4);

By default, the GeoDistancecCalculator return distances in meters,the base unit of length in the International System of Units. If you need distances in other units, specify the unit in the constructor:

var distCalc = new GeoDistanceCalculator(DistanceUnit.Mile);
var computedDistanceInMiles = distCalc.HaversineDistance(36.12, -86.67, 33.94, -118.4);

The supported distance units are:

meter (default)
kilometer
mile
feet

Distance conversion

If needed, you can convert directly distances from one unit to another:

var distanceConverter = new DistanceConverter();
// converts 1500 meters in miles
var distanceM = distanceConverter.ConvertDistance(1500, DistanceUnit.Meter, DistanceUnit.Mile);

SaaS solution

If you are looking a ready-to-use solution for geospatial operations, you can check out proximity-map. For any address, find easily the closest location in a set of pre-defined addresses (flying and driving distances).
