##### Mid-point

Find the point half-way between two points along an ellipsoid

- Keywords
- spatial

##### Usage

`midPoint(p1, p2, a=6378137, f = 1/298.257223563)`

##### Arguments

- p1
longitude/latitude of point(s). Can be a vector of two numbers, a matrix of 2 columns (first one is longitude, second is latitude) or a SpatialPoints* object

- p2
As above

- a
major (equatorial) radius of the ellipsoid

- f
ellipsoid flattening. The default value is for WGS84

##### Value

matrix with coordinate pairs

##### Examples

```
# NOT RUN {
midPoint(c(0,0),c(90,90))
midPoint(c(0,0),c(90,90), f=0)
# }
```
