I'm new to Trimble Business Center, and have a processing question. How do I get TBC to hold user enter values for a control point when processing? Can I not enter a grid coordinate for the reference value? Do I have to enter a global value? I'm trying to be able to process vectors with respect to the NAD83 (2011) reference frame. A small difference than using WGS84 vectors and holding current NAD83 Coordinates. TBC organizes it by local, grid, and global coordinates. Will it only use global coordinates for a reference value?
Is there a pre-transformation process in TBC, like Leica? Or only datum coordinate transformation?
Thanks in advance.
You can hold to a grid, local, or global coordinate. When I'm using state plane coordinates I use the NAD83 null transformation, so the values for global and local are the same. I prefer to hold global coordinates as a personal preference, but the software can work with any.
Are you familiar with the Project Explorer? If not you need to become familiar with it, it's definitely your friend. In the Project Explorer expand Points and then expand the point of interest. You will see coordinate records that were generated by the data collector and/or receiver. These can be edited, or you can add a new one. I usually either edit or delete bogus records such as autonomous positions, but you can also simply disable them, or enable them as checks.
To edit a position record right-click on it and choose Properties. Change the coordinate quality to Control and edit the coordinate as needed, make sure it's enabled, and it will be held.
TBC has some very good embedded tutorials that you may want to check out.
Maybe I'm doing something incorrectly. I create point 101 (office entered). I'd like to process based on the entered grid/local/global value. So then I import raw data and assign it to 101. When I process to a rover from 101, it holds the global value of the autonomous/navigated position. Does it need to be disabled? For a big project where I return to a base for multiple days, will I need to disable every single autonomous value for every session in TBC?
Thank you.
When keying in the point change the quality to control by clicking on the ? in the Add Coordinate box. If you only have 1 keyed in control point that will be used as the starting coordinate for processing
Yes, thank you. I fumbled around with it some more and discovered the icons. It also seems to be a way to change the direction of processing. When multiple solutions exist from multiple sessions of one point-will TBC average them until you adjust the data?
That depends - open your Project Settings and see what you have set under Computations.
Not unless you tell it to in the project setting. This drove me crazy because the final answer was always the last baseline processed.
