We’ve released the long-awaited Inverse and Traverse tools in the Emlid Flow app and Emlid Flow 360. No more calculations in third-party software—new tools are accessible directly from the project, and everything you do is shown on the map.
Inverse
The Inverse tool shows the information about the collected geometry for further decision-making in the field or in the office.
Open the Inverse tool in a project and select any number of points. Depending on the points count, you can get these types of calculations:
Direction (Azimuth)
Slope distance
2D distance
Height difference
Grade
Delta E/N
Area
Slope Perimeter
2D Perimeter
Traverse
The Traverse tool creates new geometry and helps you transfer a survey plan to a real site, quickly refine the project design in the field, and calculate inaccessible points.
Open the Traverse tool in a project and select a starting point. To create the next point, you can enter
Distance,
Direction (Azimuth),
Height difference.
To save the new point, don’t forget to enter its name, description, and code.
Inverse and Traverse are available with the Survey Plan in Emlid Flow, along with localization, linework, coding, satellite map, and WMS layers. Try it out with a free 30-day trial.
To get more information about working with the new tools, check out our Inverse and Traverse guides.
Yes, I agree with @kencormier.nsls . Decimal degrees are a good option to have if you don’t have a converter from dd.dddd to dd.mmsss, you can add or subtract. Even then you’ll need a converter to DMS to DEC format. But most if not all surveyors use the DMS format. All of our old plats, maps and plans are in DMS format.
Volume computations in the field might be great, but I’ve never in my 50 yrs of surveying provided field computations to a client, especially any volume computations. I’ve always verified field computations in the office. But to each their own.
I think this may be beyond Emlid capabilities at this moment of their development, Emlid currently needs to concentrate on their basic COGO functions foremost.
They have come a long way since I first bought their M2’s 4 yrs ago… they have a great future as far as I’m concerned.
Hi, great job! I’ve been a happy Rs3 owner for a few months now and I really appreciate your commitment to the continuous development of the app.
The new inverse and traverse functions are definitely useful, but I would have a suggestion for a further implementation. It would be great if it was possible to copy a direction with the inverse function, including the calculated angle, and then use the traverse function to project the same direction.
I tried to do this by copying the angle from the inverse function, but unfortunately it is not possible to paste it into the angle field of the traverse function (in the iOS app). This functionality would be really important, especially in work settings, to increase the accuracy and speed of work
I understand what you mean. I’ve reported this to the developers, and they suggested a workaround: copy the angle with three decimal places, and it should work.
Within the inverse tool is there a way to select all points for area calculation?
On my computer i have to option to select all but within the app i cannot find the same option.
Also does the area calculation take slopes and falls into consideration or is it purely in a 2d space?
Currently, there is no way in Emlid Flow 360 and Emlid Flow to select all points for Inverse. When you click “Select All” in Emlid Flow 360, it won’t allow you to select all the points.
Also does the area calculation take slopes and falls into consideration or is it purely in a 2d space?
For now, the computed area doesn’t consider the slope.
We’re excited to announce that we’re enhancing our blog and are looking for interesting use cases featuring the Inverse and Traverse tools in Emlid Flow and Emlid Flow 360. If you have any experiences or stories to share, we’d love to hear from you! Your contributions could be featured on our blog, showcasing your use of these tools.
