land-xml-to-geojson

This was an effort to write a LandXML to GeoJSON converter.

While it does work in a limited way, and only for the easy parcels, it will only work for simple cases where there are real world coordinates.

Also note that two cases are unhandled, currently: Curves and IrregularLines. TODO: implement some kind of solution for these!

Usage

To use it, you'll need to get an XML file loaded as a string, and then pass it in, like this:

conxt xml = '<?xml version="1.0" encoding="iso-8859-1" ?>'  // This should be valid land-xml
const landxml2geojson = require('land-xml-to-geojson')
const geoJson = landxml2geojson.convert(xml)

For another example of loading an XML file, see the test.js file.

Development

To develop, set up the dependencies with yarn or npm install.

You can run the test with yarn test or npm run test.

(I took inspiration for the structure from Turf.js, thanks!)
