close probably…but Sept end of beta.
Not sure Localization is ready or implemented??? We’ll have to wait and see.

You actually want at least 3 boxing in the site as best is possible. Remember that pretty much everything we do is based on trigonometry. One point is plane that can rotate on x and y, two points rotates on y and three points somewhat nails it down, but can leave the localization weak on one end unless the site is triangular. Boxing a site in with four points is the best method. Because it is distributing the error across the entire site preferably those four points all have good xyz values. Two verticals would be okay as long as they are on opposite extents of the site.

Good points. No pun intended.

QGIS is an excellent platform to perform coordinate transformations - Geographic or Projected - as well as georeferencing. Esri ArcGIS is the best, but prohibitively expensive.

I haven’t given any serious time yet to QGIS, as I have WAY TOO MANY software applications under my belt in many different aspects and not sure I need to add this one just yet… BUT… can it be used in the field connected to any of the Reach receivers, and used to collect points, stake out points, GNSS local transformation etc? I.e.like everything in FieldGenius?
Or is it mainly an office product?
Again, I haven’t spent any considerable amount of time with it… but I do see the benefit of it for coordinate systems, projections, georef, vector layers, etc.
I may dive into this one soon also for in the office work. ; )
Edit: derrrrr… totally forgot @Brent_W tutorial on QGIS!
Using QGIS as survey tool | Reach RS/RS+

QGIS is primarily an office product, but there is QField. I don’t use it because it is Android, and I use iOS in the field as my primary interest is drone mapping. If you have any GIS experience, it is not to difficult to learn (but then again, I have been doing GIS professionally for 30 years). I just collect my unprojected points in the field, feed those in with the GPS tagged aerial photos from my drone, create an aerotriangulated orthomosaic, and then transform it to a projected coordinate system, and do a local transformation if necessary. I also layout check points with the ground control points to confirm the measurements. I am hoping that the Reachview Survey tool will be sufficient for my needs since I need to bring the unprojected coords back to the office anyway.

With QGIS you will have everything Reachview is missing so you’ll be fine.

That is not always true , but stuff has to get done

QGIS isn’t intended to layout points (other than visually) but it can be used on the field (on a windows tablet, etc.) to save points, make polygons, convert files, make lines, divide lines into points, do any raster operation, view your background imagery, shift points, and much, much, more. You can also produce your finished site plan in QGIS.
- We need to crowdfund a layout (stakeout) plugin for QGIS.

Though you can create points files and DXF linework for export/import in QGIS. At least Reachview will accept the points, but unfortunately you still have the incapability of using State Plane coordinates so all of your work would need to be done in QGIS and then transformed to WGS84. It’s actually ALLOT easier than it sounds once you have done it a couple of times.

I do not use my Reach receivers in a construction environment but i find this discussion very interesting. I use NTRIP with CORS but i also use LORA and now PPK as there are sites i am working at where there is not cell service. i would highly suggest you get the second reach unit and do LORA as your day to day accuracy/repeatability and speed of set up will be so much better.

i agree as it would seem to be easier to built in QGIS given the existing building blocks and then maybe port it to qfield. the recent developments in proj4/proj6 would seem to address some of the trickier issues with going from WGS84 to stateplane and providing ground to grid conversion on the fly.
