There are three options for locating the data into the world, GEOCENTRIC - use lat/longs and then project onto an elliposoid GEOGRAPHIC - use lat/longs but in flat earth PROJECTED - use flat earth projection such as UTM etc. The locator takes the non dimensional coordinats of the source data layers (0,0 to 1,1) into the above cooordinate frame.
