Contour map generator
Free contour map generator
Create topographic contour maps from real elevation data — free, in your browser, no signup. Generate contour lines for any place on Earth and export PNG or SVG.
How to create a contour map
From a place name to an exportable map in three steps — no GIS, no data wrangling.
- 1
Pick a location
Search any city or drop a pin on the map. TopoLines pulls real SRTM elevation data for the area you frame — no dataset to download, no GIS software.
- 2
Tune the contours
Set the contour interval, colour ramp and line weight. Watch the contour lines redraw live as you adjust the relief and the height-based colouring.
- 3
Export PNG or SVG
Download a crisp PNG for the web, or a clean vector SVG that scales to any size — ready for print, posters, or dropping straight into Figma.
A contour map maker built for design
Real elevation data
Every map is built from actual SRTM / high-resolution DEM data, not a stylised filter. The contour lines match the real terrain.
PNG + vector SVG
Export a raster PNG or a fully editable SVG. Vectors stay razor-sharp at any print size and open natively in Figma, Illustrator and Inkscape.
Colour by height
Colour the map by elevation with built-in ramps, or design your own — from subtle single-tone lines to bold hypsometric gradients.
Anywhere on Earth
Mountains, coastlines, whole countries or a single valley. If it has relief, TopoLines can trace its contour lines.
No signup to start
Generate and download a free PNG straight away — no account, no email. Upgrade only when you need HD, SVG or larger areas.
Made for designers
Not a GIS tool. Clean output, sensible defaults and a live preview, built for people who care how the map looks.
Contour maps made with TopoLines
Every one of these was generated from real terrain data. Open any to see the place page, or make your own.
Frequently asked questions
What is a contour map generator?
A contour map generator turns elevation data into a map of contour lines — curves that connect points of equal height. TopoLines does this automatically: you choose a location and interval, and it traces the contour lines from real terrain data, then lets you export the result as PNG or SVG.
Is the contour map creator free?
Yes. You can generate and download a free PNG for any location without an account. A paid plan unlocks high-resolution PNG, vector SVG export, finer 10 m elevation data and larger areas.
How do I create a contour map of a specific place?
Open the editor, search for the place or drop a pin, then frame the area you want. TopoLines fetches the elevation data and draws the contour lines instantly. Adjust the interval and colours until it looks right, then export.
Can I export the contour lines as SVG?
Yes. TopoLines renders a clean, layered SVG where each contour is a real vector path — perfect for scaling to poster size or editing in Figma, Illustrator or Inkscape. SVG export is a paid feature.
What is the difference between a contour map and a topographic map?
A topographic map shows the shape of the land, most often using contour lines to represent elevation. Contour lines are the core of a topographic map, so a contour map generator is effectively a topographic map generator focused on that relief.
