OSM map: get GeoJSON instead of converting GeoTIFF → GeoJSON
Looking to turn a map from GeoTIFF into GeoJSON? If your data comes from OpenStreetMap, you do not need an intermediate GeoTIFF file: osm2cdr builds the map straight from the OSM source and hands you a ready GeoJSON. That is faster and more accurate than the chain "download GeoTIFF → upload to a converter → get GeoJSON": you pick an area on the map, choose the GeoJSON format and download the result with up-to-date OSM data and layers for buildings, roads, water and features.
How GeoTIFF differs from GeoJSON
| Format | Extension | Type | Purpose |
|---|---|---|---|
| GeoTIFF | .tif | Raster | GIS analysis, remote sensing, CAD base maps, orthophotos |
| GeoJSON | .geojson | GIS | Web mapping, geodata exchange via API, Leaflet/Mapbox visualization, analytics |
How to get GeoJSON on osm2cdr
- 1Select an area on the map on the osm2cdr home page
- 2Choose the GeoJSON format and, if needed, a style and CRS
- 3Click Export and download the ready GeoJSON file

When you need GeoJSON
The GeoJSON format is handy when you need to open the result in a dedicated program and keep working with the map: editing, printing, analysing or embedding it in a project. osm2cdr delivers GeoJSON split into layers with up-to-date OpenStreetMap data, so the file is ready to use right after download.
What changes when going GeoTIFF → GeoJSON
A GeoTIFF raster is pixels, while the GeoJSON GIS format expects objects with attributes; an honest conversion needs vectorisation, which is always approximate. osm2cdr does not vectorise your raster: it takes OpenStreetMap vector data and builds GeoJSON with real objects, layers and a projection.
If you have your own GeoTIFF file (not from OSM)
osm2cdr does not accept or convert third-party GeoTIFF files: the service works only with OpenStreetMap data. If you already have your own GeoTIFF file that is not from OSM, convert it to GeoJSON with third-party tools: GDAL/ogr2ogr from the command line or QGIS — open the GeoTIFF and save the layer as GeoJSON. It is free and runs locally, with no cloud upload.
FAQ: GeoTIFF → GeoJSON
Can I upload my GeoTIFF file?
Not yet: we don't support uploading GeoTIFF files at the moment, so convert your file to GeoJSON with ogr2ogr or QGIS. And if your data comes from OpenStreetMap, you don't need a file at all — osm2cdr exports the map straight into GeoJSON.
Is it free?
Yes, exporting an OpenStreetMap map to GeoJSON on osm2cdr is free. Select an area, the GeoJSON format and download the result.
Which programs open GeoJSON?
The GeoJSON format opens in dedicated programs for its category. See the GeoJSON format page for the full list and details.
Why is this better than an online GeoTIFF → GeoJSON converter?
An online converter caps the result quality at the quality of the source GeoTIFF file. osm2cdr takes data from the OpenStreetMap source and builds GeoJSON with correct layers directly — with no loss on an intermediate GeoTIFF file.
