Transform OSM data

[seanerice]

Coalesce into a single attribute

• cycleway:right, cycleway:both, cycleway => cyclewayRight
• cycleway:left, cycleway:both, cycleway => cyclewayLeft
• cycleway:right:buffer, cycleway:both:buffer, cycleway:buffer => cyclewayRightBuffer
• cycleway:left:buffer, cycleway:both:buffer, cycleway:buffer => cyclewayLeftBuffer

For roadways, assign a category

1. cycle track
2. buffered lane
3. lane
4. shared busway
5. shared lane
6. none

For dedicated rights of way, determine access level

1. bicycles allowed
2. bicycles designated
3. bicycles not allowed
4. conditional access

Keep in mind that there are default values for each type of dedicated ROW. Paths are bicycle=yes by default Cycleways are bicycle=designated by default

Filter out data:

• ways where bicycles are not allowed
• ways where bicycle paths are marked separately (ex: cycleway=separate)

Filter out attributes that aren't relevant. This should cut down on map size.

I have updated the fetch script to also transform data. I have also simplified how the map is created.

I'm satisfied with the state of the script. Going to close this issue.
