i would like to request that tbc be able to handle multiple adjustments in one project. i will outline bellow a couple types of projects where this would be valuable. each adjustment could be named similar to creating a surface and maybe even placed on a layer to be turned on and off and to be able to manipulate each individually and also fix one or be able to add data to it. secondary to this, having each data collector file on a layer and being able to turn each one on and off would be invaluable. these could be groups of their own in the project manager so that their points and ties can still be turned on and off as normal. or some sort of branch grouping.
usually this applies to large projects where there can be lots of data.
large sites where there is physical obstructions preventing ties. maybe a large river with a base station on each side but the project is on both sides. or very long corridors with limited helicopter access. we have had both of these occur. if you process a data set without ties in common from two base station setups then tbc returns an error. "can not compute multiple subnets in project". or something like this.
large construction projects. what i have in mind here is a electrical tower installation project with many days worth of data. in this case, there is overlapping data where we topo each tower location, rough layout, set control, resect and check tower foundation, retopo construction…..
in this case mostly we can make a new tbc project for each days work and it is relatively easy to keep organized. but when it comes to the resection work doing multiple towers from one data collector file things become way more tricky. i don t want all the data from topo work from previous days so would typically import a control point csv. but then each resection becomes its own subnet and needs its own tbc file. if there is rtk topo data on top of this from the same data collector file then all that needs to be wiped out or blended with each resection.
another type project where this is a real pain is on projects with multiple base stations and crews return to the site doing total station work off of control from both base stations. here the datasets needs to be imported to both projects and total station work erased from each that is not relevant to the subnet. keeping track of all the data becomes way more work than it should be.
i realize that merging projects and referencing projects might be a way around this, but i am not sure this gives full control of adjustments between projects and is only on the higher level tbc keys(last time i looked). maybe others have better approaches to these problems?????
thanks
