TOP2NEZ

Topcon is one of a number of of Electronic Distance Measuring (EDM) instruments. It can be controlled with an FC4 module that stores measurements in an ASCII format assuming a Microsoft file convention. For example, consider a file survey.n:

00001
10000.00000
10000.00000
1000.00000
BP1 
00003
10000.00000
10000.00000
1000.00000

There are tags, sequence numbers and (y,x,z) coordinates, one item per line. This program converts the file to a NEZ file format, all items in a single line corresponding to the tag. For example, if we issue the command top2nez survey.n,
we have output file survey.n.nez:

00001       10000.00000 10000.00000 1000.00000  BP1         
00003       10000.00000 10000.00000 1000.00000  C2-48

The NEZ format is read by BSU programs. Program TOP2DXF 10.1.14 can be used to create a CAD file for making base maps.
