Project Coordinate System

Use the “Coordinates” section to configure the units and projection system used by the project.

The following table lists the properties found in the Coordinates section and describes their use:


A horizontal datum is a reference system used to define positions on the Earth's surface using latitude and longitude. It's essentially a coordinate system that helps pinpoint locations geographically. This system relies on a mathematical model of the Earth's shape, often an ellipsoid, and a specific anchor point.

A vertical datum is a reference surface used to define vertical positions, essentially serving as the "zero point" for measuring elevations and depths on Earth. It's crucial for consistent and accurate height measurements in various fields like surveying, hydrography, and navigation.

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

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.
