Earth to Globe to Map Map Projection: Map Scale: Scale Factor, k Representative Fraction Globe distance Earth distance = Scale Factor, k Map distance Globe distance = (e.g. 1:24,000) (e.g. 0.9996)

Extent of New Zealand 34°S to 48°S Central Meridian 166°E to 179°E

Transverse Mercator Projection A cylinder surrounding the earth and touching it on one Meridian For New Zealand, this meridian (line of constant longitude) is 173°E

New Zealand Transverse Mercator Projection (NZTM) (1600000, 10000000) Origin: Latitude = 0° Longitude = 173°E False Easting (X) = 1,600,000 False Northing (Y) = 10,000,000 Latitude of Origin = 0° Central Meridian = 173°E UC Engineering Building (1566365, 5181181)

Representations of the Earth The Geoid is a surface of constant gravitational potential Earth surface Ellipsoid – NZ uses a standard ellipsoid called GRS80 Sea surface Geoid

Plate Tectonic Movement

New Zealand Geodetic Datum Establishes vertical location as Z-coordinate

NZ Vertical Datums Orthometric heights: produced using a Geoid (NZVD2016) (these are “true” heights for water flow) Tidal heights: derived from tide gages—related to sea level Ellipsoidal heights: produced by GPS on GRS80 ellipsoid (abundant data)
