Harald Schernthanner

in R this package could help: https://ropensci.org/tutorials/geojsonio_tutorial.html

https://github.com/ropensci/geojsonio

I think a porting to python exists.

Luís Moreira De Sousa

Thank you Harald for the reply. I am looking for a Python API, not an R package. In any case, geojsonio does not support the creation of TopoJSON files at this time.

Hi Luis,

A conversion to TopoJson is possible according to the package description on CRAN: https://cran.r-project.org/web/packages/geojsonio/index.html

I´ll ask a colleague who is more into python and write again.

Kind regards

Harald

Jose Gomez Castaño

Hi Luis

I think GDAL [1] is your best option. You can see the specification in [2] and an example here [3]

[1] http://www.gdal.org

[2] http://www.gdal.org/drv_geojson.html

[3] http://geoffboeing.com/2015/10/exporting-python-data-geojson/

Regards

I agree with Jose. GDAL might be the best choice.

http://www.perrygeo.com/tag/topojson.html

José and Harald: GeoJSON is not a topology format. Please check the links in the original question.

As for GDAL/OGR, the driver supports reading TopoJSON, but not writing, i.e., it does not support the creation of new topologies in this format. Please check the link below.
