Determination of distance within the voronoi-function

Hey,

I am actually working with the MATLAB internal voronoi-function (i.e. the determination of areas around some central points, where the areas are defined as the quantity of points which the shortest distance to the particular central point). My problem is that I would like to use that function for some GPS-coordinates, i.e. not for a plain area but rather for the globe. However, if I understand this right, MATLAB determines the distances with the euclidean distance which includes obviously a fault into the calculation due to the fact that the globe is not a plain area. ;)

Does anyone has an idea how to deal with that?

Thanks for your help and kind regards, Florian

Maybe some of the Mapping Toolbox distance measurements would be useful to you:

• doc distance
• doc track
• doc reckon
