Osaka Road Improvement

Posted by srividya_c on 12 November 2015 in English (English)

As part of the Japan Road improvement series, we just completed the very important Mega Nagoya where the task description was to align all the major roads according to orthorectified imagery from GSI using the tasking manager of TeachOSM.

The Nagoya task included

  • Realigning of major roads (motorway, trunk, primary and secondary)
  • Create Dual carriageways and highway_link roads with appropriate oneway tags

Nagoya was a well mapped urban area where the roads were very dense and the alignment was done by 23 excited mappers who finished the task in the period of 7days.

Next in the pipeline of improving roads in Japan is Osaka.

Osaka is a well populated second largest metropolitan city in Japan. The roads here are heavily mapped and the data density is huge. The objective of Osaka mapping task is

  • Aligning the major highways(motorway, trunk, primary and secondary).
  • Creating dual carriageways wherever needed with proper oneway tags.
