Precision

Contour Interval

Simplification Removes redundant points from each contour. Higher = smoother, lighter lines with fewer nodes (faster to open in design tools); lower = finer detail.

Approx. points per km of contour:
• None ≈ 43
• Low ≈ 7
• Medium ≈ 4
• High ≈ 3

Taper Varies contour line thickness with elevation — higher ground gets bolder lines for a layered, 3-D feel.

Relative Mode Spaces contours from the area's lowest point instead of absolute sea level — clearer local relief.

Index contours Draws a bolder “index” line every N contours — the emphasised lines that make a topographic map easier to read.

Best on desktop

The TopoLines editor needs a bigger screen to draw zones and fine-tune your contour maps. Open it on a laptop or desktop for the full experience.
