Adjustment software - considering Star*Net

islandoffset · 2023-10-13T14:44:57Z

Hi,I haven't mined every thread in this discussion forum, so I apologize if I'm asking a duplicate question here.The company I work for does a lot of bush surveying for resource industries - and I'll note, we work in BC, Canada. In the last year, we've gotten larger and larger projects where we are, for example, surveying a remote access road 50km long with 20 bridge crossings throughout, where we need to fly in, set control, tie into other lidar/old survey data, do our designs, and get confidently set up for construction supervision/layout. This is a typical work flow for us, but on a much larger scale, with more companies involved and more on the line. We survey with Leica total stations, Hemisphere RTK units, and Field Genius software. In the office, we use Civil 3D mostly, with RoadEng for road designs and a bit of lidar-processing support, Autodesk Recap just for processing LAZ/LAS files, and a basic version of Leica Infinity for when we need to investigate possible rod height errors etc. My question is hard to sum up - I'm looking at Star*Net for a new addition in our work flow. I have spoken with MicroSurvey and done some online research, and having an 'adjustment software' seems really valuable to process our survey control and give us confidence in our results. I've heard that Star*Net is the most popular adjustment software in NA. Does anyone have feedback on - - The application of Star*Net for our needs? Could I take my RTK data, some total station data, and combine it into a large topo map with solid survey control - with reports/numbers to verify our results? Currently, I stitch all survey data files together manually in Civil3D, often relying on best fits. This is time-consuming, has too much room for human error, and I don't have a good way to quantify and display, at a glance, the confidence of my results. - Other, better adjustment software programs? I spoke to a Leica rep to look into getting an expanded version of Leica Infinity, but was told it is a bit more finicky, and less popular, as they use a European-based adjustment method. - Our survey process in general - do I not even NEED adjustment software? How do you ensure tight results when setting survey control and gathering lots of topo data? If you're left with 3-4 shots on one base station/benchmark that was set the first day, then picked up on following days as checks, but they are all 1-5cm off horizontally/vertically, how do you decide where the 'right' location is and document this? I really appreciate any feedback! I have a sneaking suspicion this is too broad of a question, but I need to start digging in somewhere. I also realize that our field surveying practices may need tweaking, but that is another post. We generally follow the Canada RTK surveying guide and use NRCan's Precise Point Positioning website to post-process our RTK raw data. Let me know if I can clarify! Thanks for reading.IO

There are built in importers, however my first experience was with manual entry, we wrote our own software that converts the observations from Trimble jobxml files and Topcon GLS2000 GLS2200 project directory structures read from the SD card.
