The import stores the measurements in the Survey database, and processes the data for the calculation.
- Standard Deviation—The import function determines the standard deviation for each observation, according to the instrument settings.
- Point Type—The import function determines the Point Type of each measured point, according to the key in the import file. For example, in a (*.RO) file, points with the key AP, or ST are of type Base Point, and points with the key NP are of type Detail Point. For detailed information see description of input formats.
For example, in a GPS session, or in a coordinate (*.RO) file, points with the key K, and C=1-2, are of type Base Point. Points with key K, and C = 3-9 are of type Detail Point.
- The measurements are stored in the system table TB_SUR_MEASURE.
Session
In the Survey database the measurements are stored session-wise. A session is a set of observations that has been imported into a calculation project. A session can be of type GPS, Tachymeter, or Control Distance.
- For coordinates, each import file is assigned to a GPS session.
- For tachymeter files, each station is assigned to a Tachymeter session.
In the Results dialog box, on the Measurement Results tab, you can view the session of the observations. See also Result.
