Moving to 3-D ArcGIS can be a daunting task. However with the advent of a Low Distortion Projection (LDP)moving to 3-D ArcGIS can be both exciting and possible. GPS can now collect z-coordinates that are applicable to the 3-D environment. Survey pins on the ground seems to match the coordinate grid more accurately. ArcGIS system with the best of both worlds (GIS and GPS). Correcting layers are now more manageable then using contour lines by draping and associating the z-coordinate to all layers.
