Open wizzfizz94 opened 6 years ago

wizzfizz94 commented 6 years ago

Need a way pass attribute data across. possibly to feature properties.

Phrogz commented 6 years ago

Can you elaborate on this request? What attribute data do you want passed, to where/what function, for what purpose?

I'm not wizzfizz, but we're have something like this:

<g id="WATER">
  <path id="POOL" d="M11333.8,11015C11356.3,11167 11234.8,11334.9 11330.6,11448.9C11426.5,11562.9 11705,11651.8 11801.8,11507C11898.6,11362.2 11974.9,11173.8 11974.9,10979.8C11974.9,10785.8 11940.3,10569.1 11859.3,10440.8C11778.2,10312.6 11603.4,10207.8 11429.7,10302.1C11256,10396.4 11162.1,10541.9 11203.3,10693.8C11244.5,10845.8 11312.1,10868.5 11333.8,11015Z" style="fill:rgb(189,222,229);"/>
</g>

And we'd like the ID passed through to the feature. Not terribly fussy about how its formatted, just so we can find it programatically:

  "type": "Feature",
  "properties": {
    "id": "POOL",
    "class": "WATER WATERSPARENT"

Yes the feature that @Crisfole would like is what i meant. The ability to for all arbitrary svg attributes to be included in the geojosn parse. I think i ended up hacking the module but for a hacky hard coded fix so i wont upload it.

DavidCampbellTech commented 5 years ago

We too have the same need. We'd like to pass id's on svg elements (not just the group) all the way through to the postgis database, svg -> geojson -> shape file - db.

Its quite important in order to make interactive maps.

SimonasPetk commented 2 years ago

I solved this issue by running in debug mode. As debug mode adds svgID into the properties field. (see lib/svg2geojson.js, line 68 for part of code responsible for it.)

svg2geojson ../clean-1-part.svg --debug

returns

{"type":"Feature","properties":{"svgID":"1"},"geometry":{"type":"LineString","coordinates":[...........]}}
