LightBurn Layered Lake Map

I have a single reference image of a lake and I need it converted into a clean, vector-based design that I can open directly in LightBurn. The final file must break the shoreline into 4–6 distinct depth contours, with actual depth data from USGS each on its own layer, sized and ordered so I can cut and engrave the pattern from 3 mm plywood or MDF without further editing.

Please trace the lake accurately, simplify where necessary so tight inside corners are still cut-friendly, and make sure each layer nests perfectly within the next. Colour-code the layers the way LightBurn expects and include a separate outline for an optional frame.

Deliverables
• A LightBurn (.lbrn2) file with 4–6 colour-coded layers ready to cut
• An exported SVG (one file containing all layers) for backup
• A quick PNG preview so I can confirm the look before I run the job

I will supply the lake image as soon as we start; you return a design I can send straight to the laser.
