Hello,

Can't say thanks enough for all the work put into Little Navmap.  I've been using it to plot lines of position with the celestial nav addon for MSFS, and I've found one little convenience item that would be nice, if it's easy.  It would be great to be able to create a line measurement, click to anchor it, and then be able to grab the beginning point of it and rotate the line around the endpoint that you'd anchored.  This would be handy any time you needed to measure a course and distance to a point, and then make another measurement FROM that point.  This spot in this video illustrates what I mean, in Google Earth.

 

I don't know how complex this might be and it's probably not worth spending a bunch of time on, but just thought I'd throw it out there if it was easy.

Thanks again!

But  similar feature that can simulate it already exists in LNM 🙂

Enter "LNM Options"/"Measurement Lines" -> tick all options "on". Since this moment on the map you've got: distance, magnetic course, true, course,
radial number and navaid/airport ident displayed
Then it's enough anchor beginning of the measure line and label values near measure line are dynamically changing as you change the end point.
You can anchor it everywhere, when you need both courses you can anchor 1st line at the end and 2nd at the beginning, although I prefer calculate reciprocal course in my head (simple calculation +/- 180deg /mod 360) so only 1 line is needed here, exactly as it was in old good, "pre-computer" times.
I sometimes use this feature for  VFR flights, LNM is a great tool with many "hidden" options (sometimes even too many for my "old head" 😉 )

Regards,
Piotr

Hi Piotr, but this does not allow to move the measurement line at both ends.🙃

I'd not add a special anchor function but simply allow to move both ends.

I use whatever is possible to get what I want, but if you are planning add both ends movement it will be great ... 👍

In my use case, I was needing perpendiculars, not reciprocals.. and in celestial nav you aren't just measuring a course, but instead you actually need the line on a map as it becomes a line of position.  Certainly you can draw one line (measuring the offset distance along the azimuth from the assumed position), and then start a new line at the end of the first one; that's what I've been doing and it works.  It's just an extra step, and it struck me that Google Earth handles this a little differently, in a way that ends up being a little more convenient.  Certainly, it's a small item.

Yep, this is what I meant; so when either end is moved, it can be rotated around the other end.  Not sure of the right terminology but we're on the same page.  I know it's a small item and I'm not sure how complex it would be, but thanks for considering!

• Better measurement line handling: Tooltip and hotspot for measurement lines is now origin and end. The line can be moved from both ends.
• Measurement lines can now be the origin of a userpoint showing its label.

Duuuude... thanks much for this!  Freaking perfect!

You're welcome. 🙃 I like this feature too.
