Bearing with camera and draw line on map

Here ist my suggestion for the new function:

is it possible to implement a compass bearing function with the camera

like the app in Locus.

The idea is to look through the camera of the android, bearing a object

and after pushing a knob there will be a line drawn on your map with

predefined length to the bearing direction and stored as a track in Locus

I try to describe what I think

- I take my Smartphone start Locus

- Start a bearing function with camera

- look with the camera to a point for example at the horizon. At the display I see the point and a cross. I put the cross on the point.

- Then I push a knob on the display

- My actual position and the course to point will be stored as a line.

- Locus should show me now a line from my stored position to the point on the map

- This line is also stored as a trackline in Locus

This function is need for identify the location from objects by bearing from different places.

For example: You see a tower far away. You don't know the position. Now you can bear the tower and draw a line. The same you can do from some more positions. Now you get several lines on the map. The position of the tower is now where the lines are crossing on the map.

This is a kind of visibility navigation.

There are a some apps with the camera bearing function. But no app stores and show a vector line on a map.

If Locus would implement such a function it is realy new and it is useful for cross navigation.
