AFAIK, true bearing differs in time and location because of magnetic declination. So I don't think there is a such thing as a CRS with true bearings.
Assuming you are working at regional level, find the magnetic declination for that region and remove it from your observations. Then draw the azimuth using the chosen CRS. I think 26910 will work just fine. If you are at a larger scale, then you may need to use different magnetic declination values for each observation. This may help: https://www.ngdc.noaa.gov/geomag/declination.shtml Best Regards, Alexandre Neto A seg, 2/04/2018, 23:54, Springfield Harrison <stellar...@gmail.com> escreveu: > Hello, > > I am using CRS 26910, NAD83 / UTM zone 10N, and need to draw lines at > exact true bearings.
