orb/project 
Package project has helper function for projecting geometries.
Examples
Project orb.Point to Mercator:
sf := orb.Point{-122.416667, 37.783333}
merc := project.Point(sf, project.WGS84.ToMercator)
fmt.Println(merc)
// Output:
// [-1.3627361035049736e+07 4.548863085837512e+06]
Find centroid of polygon in Mercator projection:
poly := orb.Polygon{
{
{-122.4163816, 37.7792782},
{-122.4162786, 37.7787626},
{-122.4151027, 37.7789118},
{-122.4152143, 37.7794274},
{-122.4163816, 37.7792782},
},
}
merc := project.Polygon(poly, project.WGS84.ToMercator)
centroid, _ := planar.CentroidArea(merc)
centroid = project.Mercator.ToWGS84(centroid)
fmt.Println(centroid)
// Output:
// [-122.41574403384001 37.77909471899779]
