As a trainee surveyor learning to process, I've been thrown in at the deep end to process some of my own work as practice, and i was wondering if anyone could offer advice on the best way to go about it?
I've recently done a survey in Newcastle, UK. The survey was 2200m of road and was done by traversing in control points every 150-200m.?ÿ
The usual way of processing smaller jobs is by putting my local traverse co-ords through bowditch or least squares (job dependent) then once this is done, transforming the job in LSS by using the GNSS co-ords i took of the first and last control stations.?ÿ
Now as this is a job over 1000m i believe that i should use a scale factor, however i have never applied one to a job before. I have worked out the scale factor but i am not sure in what step i should apply it. Would i scale by E/N before i put through starnet, and then transform afterwards?
Could anyone give some practical steps in order of how i would do this? Thank You.
Do you want the results to be in a projection system (assuming the GNSS solution was expressed in a flat projection) or on ground? The scaling could take the projection system to ground to merge with the traverse, or vice versa.
Star*Net may be able to handle the conversion for you, but I haven't used a recent version to know for sure.
What system is LSS transforming your coordinates into?
