Open Lac La Belle 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.
Survey facts
| Location | Keweenaw County, Michigan |
|---|---|
| Centre | 47.3756° N, 88.0059° W |
| Survey area | 4.1 km east–west × 2.0 km north–south |
| Depth data | Survey contours |
| Source | NOAA nautical charts: Great Lakes basin lakes. NOAA Office of Coast Survey electronic navigational charts; public domain. Chart contours and soundings interpolated by TopoStack; not for navigation. |
Interpolated from NOAA nautical chart contours and soundings, which are generalized for navigation. Depths are below Low Water Datum, not a live water level.
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 × 147 mm (12 × 5.8 in) | about 1:14,000 |
| 406 × 196 mm (16 × 7.7 in) | about 1:10,000 |
| 610 × 293 mm (24 × 11.6 in) | about 1:6,800 |
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.

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.
