# Project Coordinate System Use the “Coordinates” section to configure the units and projection system used by the project. [](https://help.mystart.com/uploads/images/gallery/2025-03/3zXimage.png) The following table lists the properties found in the Coordinates section and describes their use:
Time Zone | The time zone for the project’s location. |
Horizontal datum | Horizontal datum used by the project. These are the supported horizontal datums: - World Geodetic System 1972 (WGS 72) - World Geodetic System 1984 (WGS 84) - Geodetic Reference System 1980 (GRS 80) - North American Datum 1927 (NAD27) - North American Datum (NAD83) - North American Datum (NAD83 2011) - North American Datum (NAD83 HARN) - North American Datum (NAD83 CSRS) - Geocentric Datum of Australia 1994 (GDA94) - European Terrestrial Reference System 1989 (ETRS89) - Australian Geodetic Datum 1966 (AGD66) |
Vertical datum | Vertical datum used by the project. These are the supported vertical datums: - World Geodetic System 1984 (WGS 84) - National Geodetic Vertical Datum 1929 (NGVD 29) - North American Vertical Datum 29 (NAVD 29) - Canadian Geodetic Vertical Datum 2013 (CGVD 2013) - Canadian Geodetic Vertical Datum 1928 (CGVD 28) - Denmark Vertical Reference (DVR 90) - Norway Normal Null 2000 (NN2000) - Norway Normal Null 1954 (NN54) - Deutsches Haupthoehennetz 1992 (DHHN92) - North American Vertical Datum 1988 (NAVD 88) - North American Vertical Datum 1988 (NAVD 88 GEOID12B) - North American Vertical Datum 1988 (NAVD 88 GEOID12A) - North American Vertical Datum 1988 (NAVD 88 GEOID12) - North American Vertical Datum 1988 (NAVD 88 GEOID09) - North American Vertical Datum 1988 (NAVD 88 GEOID06) - North American Vertical Datum 1988 (NAVD 88 GEOID03) - North American Vertical Datum 1988 (NAVD 88 GEOID99) - North American Vertical Datum 1988 (NAVD 88 GEOID96) |
Projection | Projection used by the project. These are the supported projections: - Latitude Longitude - Longitude Latitude - Earth Centered Earth Fixed - Mercator - Universal Transverse Mercator (UTM) - Transverse Mercator - Lambert conformal conic - AEAC - AMG - MGA |
Units | Determines whether units represent meters of feet. |
Voxel Size | Voxels are cubes. This parameter determines the length all sides in a voxel’s cube. |
Project Origin X, Y, Z | The origin coordinates of the project, in units. This point becomes a reference point for the project. |
Min X, Y, Z (read-only) | Minimum possible coordinates in the project. |
Max X, Y, Z (read-only) | Maximum possible coordinates in the project. |
