I collected a series of points for a longitudinal profile of a stream and I did not tie in one of the control points to the rest of the survey. I will be continuing the survey, and I would like to realign points 100-190 with the rest of a survey. Here's how the survey went:
TS @ CP1, BS @ CP2, shot points 100-175,
TS @ CP2, BS@ CP 3, shot points 175-190, NOT TIED INTO CP1
TS @ CP3, BS@ CP2, shot points 250-300 and CP 4,
TS @ CP4, BS @ CP3, shots points 300-400 and CP 5,
TS @ CP5, BS @ CP4, shots points 400-500
My plan is to go back to the survey site, set up the total station at CP2, set the BS at 3, and reshoot CP1. I would like to then use TopSurv to see the difference between from the the first CP1 and the newly tied in using COGO), and translate points 100-190 so that they align with the rest of the points. This is a remote location, so I want to make sure that I have a firm understanding of how to do this before I go out. Can someone give me the run down on how to align these all using COGO?
Use rotate command in the translate rotate and scale menu.. Pretty easy fix , but i would shoot cp1 and bring back to the office to fix. Not to question your procedures but why is your traverse not connected how can you set traverse Cp3 with out backsite cp1 ?
One step that I did not mention was that I shot CP3 from CP2, then moved the TS to CP3, set BS@2 and shot points 175-190. Does that make sense? Also, I currently only have TopSURV software and EFT software (very buggy) for processing data, which is why I was hoping to make the fix in the field using the data collector. I am in the learning stages of collecting and processing this type of data, so I have not purchased processing software just yet. I do have ArcGIS at this point, but I am not sure if there is a way, and if so how, to make this type of correction. In the near future, I will most likely be using AutoCAD and/or RiverMorph for processing. Do you have any other suggestions?
Sounds like 2 was tied to 3 and 1 was tied to 2 . so all you need is the points shot from 1 rotated on to the rest of your work . set up on 2 bs 3 shoot 1 . Rotate the points shot from 1 around point 2 using the new point 1. The other thing is if you did set up on 2 and bs 1 then those points need to rotated as well . I would really need to look at what you did to say for sure .
