Flight routes from an origin-destination table

Routes drawn from a table with from and to columns, matched against a built-in place index. Origin-destination tables are the most common shape of transport data, and requiring pre-built line geometry rules out most of it.

Start an editable copy with this data and your current map styling.

Loading CSV data
Routes are generated between real hub coordinates with a seeded curve so they read as paths rather than rulers. Passenger counts are synthetic.

What to look at

  • Two text columns become geometry: origin and destination are resolved to coordinates.
  • Lines bow along a curve instead of cutting straight across the globe.
  • Colour is driven by passenger volume, so the busiest corridors stand out.

Source columns

These fields describe the example data. CSV and Excel use first-row headers; GIS formats store geometry and feature properties. Required geometry depends on the map type.

Rebuild it with your own data

  1. 1

    Get your CSV file ready

    The example fields are from, to, passengers_m. For CSV or Excel, put headers in the first row. GIS files carry geometry and feature properties. Prepare any grid, catchment or route geometry before import.

  2. 2

    Drop it into the studio

    MapCrafter detects the geometry, counts the features, and shows the layers it found.

  3. 3

    Style the imported layer

    Pick which column drives colour, and which drives size or width where relevant.

  4. 4

    Pick a basemap theme

    Graphite is used here. 15 other basemaps are available, including official OpenFreeMap styles. Switch using Layers & basemap.

  5. 5

    Share or export

    Publish a link, embed the map, or export a PNG at print resolution.

Questions about this example

What file format does this route map use?
This example illustrates CSV data. The live preview uses GeoJSON geometry. MapCrafter reads CSV directly, along with Excel, CSV, KML, KMZ, GPX, GeoJSON, TopoJSON and zipped Shapefile. No conversion step and no desktop software.
What columns does the source data need?
The file used here has 3 columns: from, to, passengers_m. For tabular imports, supply coordinate columns, WKT or GeoJSON geometry, or address columns for an explicit geocoding step. Polygon and line files carry their geometry separately from these attributes.
Can I use my own data with this map type?
Yes. Open the studio, drop in your file, and MapCrafter detects the geometry and applies a starting style. Then style the layer and choose which property drives colour, size or width. The studio can render a point heatmap, but grids, routes and catchment polygons must be prepared before import.
Can I export or share the finished map?
Each map can be published to a short share link, embedded in another page with an iframe, or exported as a print-resolution PNG. The cleaned-up geometry can also be exported as GeoJSON. All of that is available on the free tier.
Where does the data in this example come from?
Routes are generated between real hub coordinates with a seeded curve so they read as paths rather than rulers. Passenger counts are synthetic.
