This group should serve as knowledge base, skills base, training base, educative base, experience share and informative base forum for all Nigerian LSU members and those interested LSU members that are not Nigerian but wanted to share contribute or needed information about what the group is meant to serve.

I will suggest you look at factors such as:
Control Points/Geodetic Datum: did you guys carried out new surveys reference to the same control points/geodetic datum as the previous survey?
Did you carried out check on control points:If yes to the above, was the control points used in situ (meaning in good conditions as same as four years ago)?
Instruments Testing: did you guys confirmed the good conditions of both the previous instruments used for old survey and the one used for the new survey?
What was the discrepancy of the old one to the new one in meters? So that we can further get to the root of the course if all the above factors weren't the course
Hi, i have a question can hopefully you can answer me, am working on a project and we have a topographic map which was done by a survey consultant company 4 yrs ago, but one of our senior surveyor is saying that these points are not correct and we have to do topo of that area again because the coordinates are not matching with his, i thought is it possible that the prism constant might be different when topo was done 4 yrs ago than what prism we are using, please tell me if am right or wrong and also please tell me what factors affect the points of topo or any survey.
You are highly welcome and we are looking forward to you contributions and wealth of knowledge you have accrue over 3 decades in the field of Surveying and Geospatial Science.
Once again, you are welcome sir!
