This is a set of three components that helps translate Earth coordinates into Rhino model coordinates. The frist step is to make sure an EarthAnchorPoint has been defined in the Rhino model. If not, use EarthAnchorPoint command to set it up. As a rule of thumb, the farther a supplied LAT/LONG coordinate is away from the EarthAnchorPoint, the less accurate its position is because of not only possible inaccuracies in setting up EarchAnchorPoint but also the fact that a globe is not flat like Rhino's XY plane.
To use, download and extract .ghpy file and place it in GH libraries folder. This script is intended for Rhino 6 and created in tandem with the Pelli Clarke Pelli Architect's R&D effort.
