Table 1. Horizontal positions and ellipsoid heights for 1996, 1998, 2000, and 2005, and ellipsoid-height changes relative to the first measurement of geodetic monuments in the Coachella Valley, California.
[Latitude, longitude, and ellipsoid height are referenced to the North American Datum of 1983. Negative values for ellipsoid–height change indicate subsidence. m, meter, mm, millimeter; ft, foot; —, no data]
