Finland Lake Depth Maps: Lakes L–O

Finland’s environment institute (Syke) publishes depth contours for lakes across the country. Some records carry only a map reference instead of a name; they are listed as published.

Larger lakes link to a page with their survey facts and sizes; the studio link beside them, and every other lake name, opens the studio framed to that lake’s survey area and generates its terrain. You can also search every surveyed lake or browse other regions.

Make a lake map from this data

Open a lake in the studio from the list. The studio frames its survey area, turns on Water depth and generates the terrain. Widen the frame and regenerate if you want more shoreline.
Check the warnings above the preview. The studio warns when survey coverage is partial or depths are estimated; how lake depths work explains why.
Enter your sheet thickness in Terrain layers; the studio works out the layer count. If a deep lake needs more sheets than you want, Fit depth compresses it while keeping the shoreline. The custom lake map guide walks through the whole build.
Turn on paint templates to spray only the water on each layer, and split the map if it is bigger than your laser bed.
Export the SVG layers. The download’s ATTRIBUTION.txt credits the survey used.
