How to Use

Upload SVG with contours

Upload an SVG with contour line paths.

Assign elevation values

Assign elevation values to contour layers or enter them manually.

Export topographic GIS layer

Download as GeoJSON LineString or Shapefile with elevation attributes.

SVG Contour Lines to Topographic GIS Data

Topographic maps show elevation through contour lines. When these contours exist as SVG paths, they can be converted to GIS LineString features with elevation attribute data for use in 3D terrain analysis, slope calculation, and digital elevation modelling.

Real-World Examples & Use Cases

Terrain Analysis

Convert SVG topographic map contours to GIS format for 3D terrain modelling in QGIS.

Frequently Asked Questions

How do I assign elevations to contour lines?▼

Each SVG layer or colour can be mapped to an elevation value. The tool generates a mapping interface to assign values by layer name or stroke colour.
