@ Norman_Oklahoma I don’t know if we could select a closer base. I could switch to a multi-base solution.
@ WA-ID Surveyor Unfortunately, we're going to have to live with those 2 unbalanced legs. Had to get around a 90° curve. Contrary to that, 2 and 5 are...
@ Jon Payne That's some fascinating stuff. Thanks for deciphering the data.
@ WA-ID Surveyor I assume you are traversing due to non-gps friendly work throughout the corridor? The office probably wants to traverse for that reas...
@ Jon Payne If you have the vector data and error ellipses for the GNSS points, why not incorporate that data into your adjustment. Great idea. Thanks...
@ OleManRiver What field software are you running with? Topcon MAGNET Field. Thanks for the advice concerning grid and ground. We got rained out today...

@ MightyMoe It’s a big subject you’re undertaking. This course is a prerequisite for SUR 2460C SUBDIVISIONS. Introduction to the residential subdivisi...
@ james-fleming Rule of v's. Thanks. This is very helpful.
@ Norman_Oklahoma The really old school way to determine a watershed area is to start at the point of concentration and draw a continuous line that cr...
