The Size of TIGER

There is a LOT of TIGER data, most of it still not even glanced at. And each TIGER road comes with a bunch of metadata tags.

way 16543325

Taginfo has the following statistics on common TIGER tags (as of Oct 6 2018):

  • 13,078,000 tiger:cfcc
  • 12,871,000 tiger:county
  • 11,874,000 tiger:reviewed (98% no)
  • 8,021,000 tiger:name_base
  • 6,880,000 tiger:name_type
  • 4,700,000 tiger:tlid
  • 4,700,000 tiger:source
  • 4,020,000 tiger:upload_uuid
  • 4,000,000 tiger:zip_left
  • 3,600,000 tiger:zip_right
  • 3,250,000 tiger:separated (99% no)
  • 1,275,000 tiger:name_direction_prefix
  • 1,127,140 tiger:name_base_1
  • 450,000 tiger:name_direction_suffix
  • 370,000 tiger:name_type_1
  • ~1,020,000 other tags with >20,000 usage

In the OSM XML format, each tag is structured like so:

<tag k="KEY" v="VALUE"/>

where KEY and VALUE are the key/value pair for the tag of course. For example, a simple highway tagged with highway=residential + name=Cole Mill Road + surface=asphalt is:

Durham Open Data!

Posted by rivermont on 5 June 2018 in English.

I recently discovered the Durham County Open Data site. Licensed under ODbL 1.0, it is a large collection of various data sources from election result data to bike racks. Some of the datasets are a few years old but most of it seems up-to-date.
Hopefully someone will be able to use this; enjoy!
