This has been a project of mine for the last few years. 
 
I hand traced the contours along the Exe Estuary which took circa 300-400 hours. This has resluted in it being as accurate as possible and looks awesome. 
 
This is a 2D Laser burnt Map onto special 3mm laser ply. 
 
Full 21 layer deep 3D map will be avialble Jan 2023 along with a Salted Swell resin edition. 
 
These are made to order and can be done any size. 
I can add on a Compass Rose, Town names, Roads etc. Please get in touch.
