Open Lake Ontario in the studio
The studio frames the survey area, turns on Water depth and generates the terrain, ready to adjust and export as SVG layers.

Sizing a piece
Framed to the whole survey area, the map keeps its landscape shape. These are the scales at three common sizes. A tighter frame zooms in and a wider one adds shoreline, and the studio recalculates both.
| Piece size | Map scale |
|---|---|
| 305 × 120 mm (12 × 4.7 in) | about 1:1,000,000 |
| 406 × 160 mm (16 × 6.3 in) | about 1:760,000 |
| 610 × 239 mm (24 × 9.4 in) | about 1:510,000 |
Your sheet thickness sets the number of layers. If the lake needs more sheets than you want to cut, Fit depth compresses the lake floor and keeps the shoreline. If the piece is bigger than your laser bed, split it into interlocking pieces.

- Make a custom lake depth map: the whole build, from framing to glue-up.
- How lake depths work: surveyed, charted and modelled depths, and what the studio's warnings mean.

Survey dates and water levels vary, and a survey can cover only part of a lake. Exports include an ATTRIBUTION.txt crediting the source; see sources and attribution. Depth data is decorative source material, not for navigation.
