Does anyone know a algotiritm that is capable of returning the geographic coordinates of a spiral, which starts at a point in space?

Example of starting point: $ lat = "-22.851479"; $ lng = "-43.232038";

Spiral type: http://en.wikipedia.org/wiki/Archimedean_spiral

There are several responses that are able to return the points in the X, Y. like: Looping in a spiral

But I'm interested in geographic coordinates.

Perhaps the conversion of coordinated planar X, Y coordinates for geographical also serve to solve my problem.

Thank you!

  • Do you want to use squares of equal area or hexagons or some other tiling scheme. And where are you planning on starting the spiral from. I think you can do it by reprojecting to a 2D surface, but the choice of projection is relevant. – John Powell Sep 08 '14 at 21:42

You can transform the x-coordinate like this x1=x+y/2 and move the axis. I'm not sure about the bucket-size but it should work with geocoordinate:Optimizing search through large list of lat/long coords to find match.
