[Talk-us] Vegetation/landuse import

[Apollinaris Schoell]

we have some very detailed data for vegetation in California and try to make a plan for an import.
Has anyone done something similar for US. Any locals interested to help? It's a huge dataset and needs some major work to be really useful. 
some challenges are
- simplification to reduce number of nodes. there are many redundant nodes and duplicates
- smoothing edges, resolution is ~5m grid and rendering looks ugly this way, some spline interpolation could really make it similar to USGS maps style
- areas duplicate nodes/lines in shape files, this should be converted to line segments and relations to avoid duplicate lines in osm. Still no simple solution for that as far as I know
- filter out useless features, urban, residential, …  areas are already covered in better ways and should be skipped
- propose tagging scheme, current tags don't support all the details in this data but should be used as much as possible to get rendering for most features
- find local experts to verify fix and upload the data.
- documentation on the wiki
