AND Data/House Number Ranges
The original AND Data contains house number ranges. These have not been imported yet, because we did not have consensus on a tagging scheme before. We want to make an effort to import the house number ranges now.
We want to kick this off in a hacking party. Date: to be set. Location: to be determined. AND would be nice, Martijn van Exel will arrange this.
We need to break this down into the following steps:
- Correlate OSM ID with AND ID for all of the Netherlands. We need to take into account ways that have been split / merged since the import, and ways whose nodes have been moved. This is the hard part. Manual labour + scripting involved.
- Find AND house number data in the source dataset and generate OSM xml.
The house number ranges appear in the AND records in the following form: (from the documentation)
hn# Housenumber range L : left, direction from FNODE_ to TNODE_ R: right, direction from FNODE_ to TNODE_ E: even O: odd M: mixed
The following tagging scheme has been proposed and discussed:
houseno:left-from houseno:left-to houseno:left-scheme houseno:right-from houseno:right-to houseno:right-scheme
'left', 'right', 'from', 'to' are to be interpreted relative to the direction if the way. This is also a major challenge: if a way is reversed later, the housno tagging must be updated to reflect the updated direction of the way.
