South Africa/ngi-river-import

Steps for importing NGI river vector data.

Vector data is provided in shp files and is divided up into South African grid squares.

Tags to keep from imported data Tag

• Filter out perennial only rivers DONE
• Develop translate filter
  • Fix up tags
    • Split english and afrikaans names
    • Strip numeric names
• Fix/determine direction of data ( automatically using DEM ? )

Use buffering on existing OSM rivers to decide which rivers to import without review, and which needs manual review. New data that is contained within buffers of existing

Manual Steps

• Change OSM tag; rivers to streams, using river plane as guideline.

• Merge small ways into larger ways ... maybe/hopefully not.
• Check flow direction.

Conflation

• Original better than import
• Import better than original or no original exists
• Do we have multiple ways for a river with number of flow channels?
