When I import a dc/job file into TBC and review the RTK vectors, I have found there are several float solutions. These vectors and points are not flagged in any way, despite the solution being float and the precisions being greater than a foot. I have looked at the settings but have not found any way for these to get flagged automatically.. what am I missing? Attached is a screenshot of an example vector and as you can see, TBC makes it look like everything is hunky-dory.
FYI, this is a GIS inventory and we have the collectors configured so crews can shoot points even in float mode... so at least we have all the attributes and an approximate position, but I'd like to make finding these bad points easier. Currently we have to do a vector spreadsheet and sort, the review each point... I'd prefer to change their symbol or flag them based on the solution type.
Any suggestions or tips?
Thanks,
Interesting... I would expect float solutions to get flagged, but we never allow them to be stored so I don't remember seeing one.
A couple things I can tell you - the error estimates reported in the field are at 67% confidence and the default in TBC is 95%, so the numbers always look worse in TBC. As you noted, you can generate a vector spreadsheet, which you can sort on any field, so segregating fixed and float solutions is easy enough (make sure Solution Type is shown in the View settings). You can also easily copy that vector spreadsheet to Excel by right clicking in the upper left-hand corner, hitting Select All, then right click Copy and paste into a spreadsheet. You could also sort on Solution Type and grab just the float (or fixed) solutions and copy just those lines to a spreadsheet.
I may try to re-create this if I can get my hands on some GPS; we're busy, all our stuff is out making $$$.
Try this ...
Create a selection set based on float solutions. You will select the vectors (Data, Arrow down (open) Select All, Select Observations, GPS tab, Check Float, Apply). All the float vectors should be highlighted. Then from right click menu, choose Select points by vector. The selection set now highlights the points whose positions were determined by a float solution. Right click and choose Properties. You will have (n) Point at the top of the properties window. Under Point Information click Layer and then <>. Make a layer called whatever to distinguish that the points are from float solutions ("Float"). Change the color of the layer to something other than white, which is the default color of a point. Ok your way out. All the float points will now be whatever color you chose. While your points are selected the right click menu reveals a few other utilities that may be useful.
