Description
TopoLines traces topographic contour lines from real elevation data, anywhere on Earth. 2.0 adds Points, a glyph field driven by the same terrain, plus annotation layers and a vector basemap. Free to try in the browser; HD PNG + SVG export on credits.

Could you build this?
Partial Extracting global digital elevation models (DEM) and dynamically computing mathematical vector contour lines (marching squares/isobands) and rendering crisp SVGs globally requires specialized GIS data processing.
What it would actually take: Building TopoLines requires sourcing and tiling global digital elevation datasets (e.g., SRTM, Copernicus DEM, or AWS Terrain Tiles) and serving them via vector or raster tile servers. The client or processing pipeline must apply marching squares/isoband algorithms (e.g., via d3-contour or GDAL bindings in WebAssembly/Rust) to generate smoothed vector contour paths and glyph fields on demand. Handling global spatial projections, zoom-level LOD simplification, and SVG export demands deep GIS/geospatial engineering expertise.
