Wishlist: Distance Ruler

[T-X]

Dear Santa :-),

It would be great to be able to use a ruler on the Meshviewer to calculate distances between nodes or any potential node sites which do not have a mesh link yet. Something like what this page provides: https://map.meurisse.org/

Is your feature request related to a problem? Please describe.

Currently it's a bit cumbersome to switch back and forth between a meshviewer map and https://map.meurisse.org for instance for planning potential nodes. Especially for 60GHz links the achievable distance is often pretty strict/limited, but (sort of) well defined: https://i.mt.lv/cdn/product_files/chart4_220326.pdf https://i.mt.lv/cdn/product_files/ptp_210150.pdf It would be great to be able to use a ruler directly on a meshviewer map to check the feasibility of a potential link.

Describe the solution you'd like

1. add a ruler icon next to the coordinate picker
2. once clicked allow adding lines on the map and display the total distance similar to what map.meurisse.org does
3. once clicking the ruler icon again then the drawn lines should be cleared

Describe alternatives you've considered

An alternative (or addition?) would be:

1. add a circle icon next to the coordinate picker
2. once clicked and after clicking anywhere on the map again, open a box (similar to where the coordinate picker has its options on the left side) with a field "Radius" where one can set a distance in meters
3. once the distance is set, a ring with the selected radius is drawn around the previously clicked point on the map

Yet another alternative of the alternative:

• simply add a draw circle option with a radius setting to the settings box of the current coordinate picker

Edit:

Additionally, there could also be two fields for "aperture angle" and "direction angle", to turn the circle into pizza slices. Which would be handy for sector antennas.
