----
go-geo-3d is a module with zero dependencies to calculate distances of 3d geospatial points.
## Installation
```bash
go get github.com/emanuelef/go-geo-3d
```
## Example
```go
package main
import (
"fmt"
geo "github.com/emanuelef/go-geo-3d"
)
func main() {
// Coordinates are in degrees and altitude in metres
start := geo.NewCoord3d(51.39674, -0.36148, 1104.9)
end := geo.NewCoord3d(51.38463, -0.36819, 1219.2)
// Distance in metres between two 3D coordinates
distance := geo.Distance3D(start, end)
fmt.Printf("Distance 3D line from start to end: %.3fm\n", distance)
posA := geo.NewCoord3d(51.3909, -0.364, 15)
// Minimum distance in metres from one 3D point to a line in 3D coordinates
minPoint, _ := posA.ClosestPointOnLine(start, end)
// Lat: 51.39181 Lon: -0.36421 Alt: 1151.37514
distance = geo.Distance3D(posA, minPoint)
fmt.Printf("Distance from one point to a line: %.3fm\n", distance)
}
```
