Drawing polylines in the xyz karezian system on a loaded scale terrain map

Good day,

I am looking for a JS+PHP spec for an assignment which is to:

- Upload a map image at a specified scale by the user

- Loading the map into a separate layer

- Draw polylines on the map in the XY Cartesian system

It is important to be able to add more than one polyline, it is also important to attract to the point from which you want to start drawing in case of crossing lines.

- Save to mysql table of drawn lines

- Additional description of break/junction points displayed on the map

- Information about the xy position of the mouse cursor

Ideally someone would make this theme using three.js
