Exporting Fractal Terrains to GeoJSON

Jhaelan · March 2017

Evening,

I'm working with Fractal Terrains and would like to share some FT worlds with folks via the web; I'm a programmer and familiar with SVG and tools like D3 so hoping there's an easy was to output or export into something I can convert to GeoJSON - I tried exporting as KMZ and converting that but it's failing to produce anything useful. Any suggestions?

Thanks

James

The vector output from FT3 is the fcw format used by Campaign Cartographer. FT will also output height fields in the Equirectangular projection (16-bit PNG if probably good enough), which external tools could use to generate contours. The KMZ output from FT is basically a thin wrapper around a generated whole-world image.

What do you want to do with FT's output?

Thanks for the suggestion regards 16-bit PNGs, I will take a look

In terms of what I'm doing, I have a FT3 world for a narrative strategy campaign I'm running in a play-by-post forum. All of the players are remote and I want to provide them with an interactive web map. I'm a web developer and reasonably familiar with SVG, D3 and similar tools so I was looking at providing layers on top of the world image for things like settlement placement, region borders and labels - where I want to allow them to switch those on and off relatively quickly, but also such that I can easily amend them without building a map processing pipeline (the contours change far more slowly than the geopolitics!). There's a collection of tooling built on GeoJSON or TopoJSON that would make that relatively easy, eg https://medium.com/@mbostock/command-line-cartography-part-1-897aa8f8ca2c

(Apologies for the delayed response, I was expecting a notification and hadn't explicitly subscribed)
