Survey supports the following unit settings.
- Industry Model units—Specify the industry model units for the values that are stored in the database. For example, you use metric or imperial units to store the length, and you use degree to store angles. The industry model units are specified when you create a industry model, and cannot be modified later.
- Measurement—Your surveying instrument records the measurements in a specific unit, such as meter or inch, degree or grade. Survey supports multiple measurement units. For example, you jointly process data that has been measured with instruments that record different units. You specify the measurement unit in the Instrument Settings. See Instrument Manager.
- Display—At any time when you analyze the results in the data grid, you can modify the display unit. For example, when you analyze the results in the Result dialog box, you display the residuals in meter, and in grade. The display unit setting is stored in the Survey database, and applies to all calculation projects. See also Working With the Data Grid.
