An overview about input data formats

Generally speaking, data formats can be classified into two large groups:

1. “raw” field data with polar coordinates
2. processed data, with XY(Z) cartesian coordinates

The latter are far more easy to process, because they don’t require any computing of measurements.

XYZ formats

These formats were the first kind of survey data format supported by Total Open Station.

Cartesian coordinates just need to be extracted from ASCII data
