Which coordinate system to choose?

[sarthak0415]

boost.geomtery have various coordinate system here, which one to choose for osm data and do user have to be given an option to choose coordinate system .
If the user wants to choose which coordinate system he wants what do we need?

this is the cartisian model followed by osm.

@sarthak-0415
this is related to #43 what would be an appropiate flag for this?

[sarthak0415]

yes we should and name is csystem

[cvvergara]

csystem what is that?

[cvvergara]

oh, c for coordinate, c for conf

[sarthak0415]

yes and defalut value should the coordinate system we are using currently

[cvvergara]

yes is c for conf? I think the name should be more meaninful,

• coord (short for coordinate)

[cvvergara]

and can you tell me what is the coordinate system osm uses?

[cvvergara]

nd also what are the valid coordinate systems that we can accept?

[sarthak0415]

we use longitudes and lattitudes from the osm file
geographic coordinate system

[sarthak0415]

that I dont know but boost.geomtery supports these coordinate systems

• cartesian
• spherical
• spherical_equatorial
• geographic

@sarthak-0415
please find out what osm use, because that should be the default.
maybe @woodbri knows?
