I projected everything into NAD83, which solved the projection issues. But I'm wondering what the difference is between these two datasets. I get the gist of coordinate systems, but my understanding was that WGS84 was a geographic …

The North American Datum of 1983 (NAD83) is the most current datum in North America. It provides latitude and longitude and some height information using the reference ellipsoid GRS80. NAD83 corrects some of the distortions from NAD27 over distance by using a more dense set of positions from terrestrial and Doppler satellite data.

bound, etc.). The NAD 83 re f e r ence sys-tem, however, does make special accom-modations for certain U.S. regions that are located completely on another plate. In Hawaii, for example, NAD 83 positional coordinates are defined as if the Pacific plate is not moving. This approach is con-venient for people who are involved with

North, I would use NAD83 over WGS84, but for most mapping applications it doesn't matter. There are lots of articles on the differences between the datums. Very simply, use NAD83 if all your data is in North America. Use WGS84 if your data is global. between NAD83 and the various ITRFs for use with the new realizations of WGS84, the bias between NAD83 and WGS84 was never acknowledged by the agency maintaining WGS84.
