coordinate system in Honduras

[RamonAntunez]

What's the coordinate system used in Honduras, along with it's Geoid model?

from this site, EPSG Geodetic Parameter Registry type Honduras in the area box, you should get a listing of unprojected and projected coordinate systems with datums, geographic transformations etc.  There isn't just 1 that is used, so you may need to clarify

Hi Ramon,

Like Dan said, there are quite a bit. The site he posted gives you quite a few systems you can use when you type in Honduras. If you click on the 'view' button next to each one, it gives you more details, like the ellipsoid model.
