Research Triangle NC Transit Import
This import has been completed. Everything else on this page was written before the import started, and should not be read as future plans.
To add every missing bus stop in the Research Triangle region of North Carolina to OpenStreetMap without creating duplicate bus stops.
The import should, if all goes well, begin in May 2019.
Data source site: GoTriangle, GoRaleigh, GoCary, and GoDurham GTFS files.
Data license: Word for word, the licence state the followingː
Type of license: Custom Link to permission: We contacted the city regarding the section highlighted in bold, and received a promising replyː
Thanks so much for your email. I have had the opportunity to speak with legal and we are going to work on updating the language of our licensing. It will take some time to go through the process but the main points are that we reserve the right to stop any or all data feeds but will not require the discontinued use if you have consumed the data when it was live. Please let me know if you have any questions and thank you for your continued support of Open Data Raleigh.
ODbL Compliance verified: Yes.
A one time import that will be completed with JOSM and the Todo plugin.
Data Reduction & Simplification
source=GoTriangle GTFS; GoRaleigh GTFS; GoCary GTFS; NCSU Wolfline GTFS; GoDurham GTFS and good changeset comments will be used on each changeset.
A python program written by Joe Caruso completed all of the data transformation (GTFS -> .geojson). All conflation, however, will be manual.
Data Transformation Results
Transformed data. - Please feel free to open this with JOSM to test the data quality.
Data Merge Workflow
A tasking manager project will very likely be created to organize the import, and the mapping community in the area will be encouraged to participate.
- Open a square from OSMUS Tasking Manager project #120.
- Download the bus stops for the square.
- Download existing OSM data into a new layer.
- Merge layers .
- Remove data not in square.
- Manually conflate new and old bus stop data.
- Upload to OSM server.
Manual effort will be the main method of conflation. This will ensure high data quality standards.
