Base Point Mismatch

[Vladimir Prasolov]

Hi Joe,

Finally I linked surveyed points to bases 502 and 503 correspondingly. First I worsened original base coordinates for points 502 and 503 directly in database. It allowed for the program to recognized linkage between bases and surveyed points. Next I restored base coordinates by using M-Local for base points 502 and 503 by using reference point 500. By the way the epoch of design point 500 has zero epoch (red epoch label). Could you say please how that point was injected into the project.

I appreciate your work, Vladimir. Point 500 was manually input by me - it's position was determined by a former static session processed by OPUS. In other words, I already had a point with good SPC on this job, so I input the point manually and used it as my base station. Is there a way to specify an epoch date when manually entering a design point? I assume that J-Field would rely on the coordinate system specified to assign the epoch date. Thanks.

You are right, J-Field relies on specified coordinate system for epoch date. Probably it was broken in that particular version.
