File Types Supported by Merge Options in Project Settings

The following file types are supported by the three "merge-by-tolerance" options in the Computations > Point Tolerances > Merge on Import section of the Project Settings dialog.

File Type	Sample File Extensions
ASCII	.csv, .asc, .txt
Data Collector	.dc
DiNi Digital Level	.dat
GNSS Job	.job
GNSS Receiver	.dat, .t01, .t02
JobXML	.jxl
NGS Data Sheet	.htm, .ds
NGS OPUS	.xml
RINEX/Raw Data	.yyo, .obs (yy = 2-digit year; for example, .09o is an observation file for the year 2009)

Other file types ignore any by-tolerance options for merging duplicate points and instead merge duplicate points only in cases where at least one of the two points is occupied by a total station or a base station (referred to as a "station point").
