Description Usage Arguments Value Side Effects See Also Examples

Finds curve coordinates of points, given points and a curve it returns the length of the points orhogonal projection and the distance traveled to the projection from a given origin on the curve.

1	orthproj(pts, curve)

`pts`	A list containing the points as \$lat and \$lon, you may also use geolocator.
`curve`	The curve to be used for projection.

Returns a dataframe with vectors pardist (length of orthogonal projection) and perdist (how far traveled alongst the curve).

None.

geocurve, geolocator.

## Not run:        geoplot(my.curve)     # Plot curve and initialize plot.
       geocurve(geolocator(),my.curve)         # Mark points.
