[Talk-es] Recomendacion de la proyeccion

["Martín RV (OPENGeoMap)"]

Hola a todos:

He mandado un correo a la lista de desarrollo de OSM para proponer un 
cambio de proyeccion y olvidarnos de mercator. La idea es hacer lo mismo 
que google earth o World Wind.

Aquí os pongo el mensaje si os interesa. Esperemos que nos hagan caso:

    Hi:

    I am an land surveyor and programmer in Spain.
    I would like to talk about the projection used in JOSM and in
    OpenStreetMap. I was studying the projection in Google Earth and
    World Wind, and i think that they have a good choice.

    They work always in the geodetic coordinates-*plate carrée*:

    x=longitude
    y=latitude
    http://en.wikipedia.org/wiki/Plate_carr%C3%A9e_projection


    Using this method you can always measure distances and angles over
    the ellipsoid using the Vicenty method and don´t need projection
    conversions:
    Here the document:

    Here source code in javascript and c#:
    http://www.movable-type.co.uk/scripts/latlong-vincenty.html
    http://www.gavaghan.org/blog/free-source-code/geodesy-library-vincentys-formula/


    Our ellipsoid is always WGS84
