Hi Guys,
Recently I have run into difficulties into Starnet again.
I have different data files from various groups and I have to create a homogenous network with it. However some files are recorded in slope distances and some are in Horizontal distances. Tried to search the forums and also the manual but it does not have a solution for this. Is there a way I am able to read all the files properly as I tried to change the job settings but it is either slope or horizontal.
I would like to find a way I can make starnet read both horizontal and slope distances without rewriting the files as each files have thousands of lines and have multiple files to go along with it.
Thanks in advance for any kind souls.
Page 83 of Version 8.0 Reference Manual
Inline Option .DELTA ON|OFF
This inline option allows you to change the "Distance/Vertical Data Type" default set in the Project Options/General dialog.
This option relates only to 3D-formatted data. When set to "OFF", subsequent data will be interpreted as slope distance and
zenith angle observations. When set to "ON", subsequent data will be interpreted as horizontal distance and elevation difference
observations.
For example, if the "Distance/Vertical Data Type" option in the Project Options is set to the "Slope Dist/Zenith Angle" setting,
the following inline options illustrate how to change to the input data to the "Horiz Dist/Elev Diff" mode, and then back again:
M 24-23-25 68-33-44.5 655.678 91-23-56 5.13/5.25
.DELTA ON
M 26-25-27 98-45-55.4 543.335 12.35 5.15/5.32
M 27-26-28 79-33-24.3 523.667 -3.21 5.55/5.43
.DELTA OFF
M 32-27-55 87-43-52.1 702.345 89-26-53 5.55/4.89
etc...
Note that "3D-formatted" data can be entered in both 2D and 3D projects. This inline controls only how the distance and vertical
information is interpreted on data lines.
If you are doing a 2-D network you could just put a 90 zenith angle on all of the horizontal distances.
Look at the INLINE OPTIONS, specifically .2d and .3d and .3reduce. Not knowing all the details, you may want to enter a very low, obviously void elevation (say -999) for 2D points in a 3d network.

Okay forgot to give more details.
I am using Starnet V6 plus.
This is for 2D networks and these data files are from various parties.
Our base networks are in Horizontal distances and 90 zenith angles. However there are some data files which are in slope distances.
For the inline options does it work for different dat files?
Thanks.
