! Data within Columbus can either be imported or entered directly using the Data Grids. ! This document describes the format of Station and Observation data records used when ! creating a Columbus input file. The format has changed slightly from the 3.X version of ! Columbus; however, you can still import the 3.X format. ! All record fields are separated by the semi-colon character (;). ! Linear and Angular values should be entered based on the units defined near the top of ! the file. ! Always enter latitude and longitude in DD.MMSSsss format. ! N 37-41-58.12345 is entered as 37.415812345 ! S 37-41-58.12345 is entered as -37.415812345 ! E 120-30-40.12345 is entered as 120.304012345 ! W 120-30-40.12345 is entered as -120.304012345 DATUM Record ! Datum Name; Semi-Major Axis; 1.0 / Flattening _DATUM; NAD 83; 6378137.000000; 298.257222101 UNITS Record ! M - meters, U - US Feet, I - International Feet, C - Chains ! D - DMS, DD - Decimal Degrees, G - Grads (Gons), ! Note: Lat and Lon must always be in DMS format (e.g., 100-30-40.1234 is entered as 100.30401234) _UNITS; M; D ! STATION Record ! We have simplified the station data input format. All coordinate data for each station ! can be entered in one record. This record contains fields for Lat/Lon, Heights, North/East ! and Deflection data. It also supports coordinate standard deviations and correlations. ! Coordinate standard deviations and correlations are not used in network adjustment. Use ! coordinate observations if you want to use known weighted coordinates that can move during ! adjustment. _STA_COORD !

There is only one set of standard deviations for both the Lat/Lon and North/East coordinate ! types: NorthSd and EastSD. ! Deflections of the vertical should be entered in the active angular units (in seconds). ! If you are creating a file for Grid Adjustment, Lat and Lon can be set to zero. In most scenarios, ! the standard deviation and correlation fields can be set to zero, since they are not used. ! ---------- _STA_DESC ! Use the _STA_DESC record to provide a description for this station. It can be defined before or after ! the _STA_COORD record. _STA_DESC; MINERS; Top Of Cliff ! OBSERVATION SET Records ! These records allow you to define a complete set of observations (e.g., Hor Angle, Slope Distance ! and Zenith Angle). ! With any observation set, if an observation was not measured or you don't want it used, simply ! enter the text "NOOBS" in the field for that observation. ! ---------- _OBS_DESC ! Use the _OBS_DESC record to provide a description for this observation set. It must be defined ! immediately above the applicable observation set record. _OBS_DESC; Unstable location with high winds ! ---------- ! AZIMUTH OBSERVATION SET !
