5 years ago Highway Classification Question
We have been reviewing Primary-Motorway classified roads for consistency and adherence to the Icelandic guidelines. Our goal is to make minor classification changes to bring all roads in compliance with Icelandic policy and we had a few questions.
Some roads don't seem to match the Icelandic Map Features wiki. For example:
Stofnvegur Routes
Based on the Icelandic Map Features wiki, the highway noted below should be 'highway=primary' as these routes are part of the Stofnvegur network https://www.openstreetmap.org/way/32197431 (highway 355)
Tengivegur Routes
Based on the Icelandic Map Features wiki, the highways noted below should be 'highway=secondary' as these routes are part of the Tengivegur network.
Additionally, these highways already have secondary highways connected to the highway we noted so we want to review some adjacent secondaries if the below highways are revised to ensure the classification is not overused.
https://www.openstreetmap.org/way/71208833 (highway 59) https://www.openstreetmap.org/way/283141513 (highway 55) https://www.openstreetmap.org/way/30283752 (highway 52) https://www.openstreetmap.org/way/13248433 (highway 48) https://www.openstreetmap.org/way/4998612 (highway 26) https://www.openstreetmap.org/way/40813630 (highway 955) https://www.openstreetmap.org/way/5376321 (highway 752)
Task Description
This task outlines work to improve map data in Iceland. The data quality is already very good and mostly complete, so these will mainly be small touch-ups on roads, buildings, addresses, water and land use. After we message the talk-is email list and get feedback and suggestions for this project, we plan to do some improvements such as the following:
Mapping Guidelines
For roads, the team will follow OSM and local policy, along with any other guidelines as appropriate.
For water and coastlines, the team will follow OSM coastline guidelines, waterways policy such as water and natural=water and local policy along with any other policy as appropriate.
Some coastlines are connected to lower level subnational administrative boundaries. In that case we will adjust the boundary with the coastline. These are not country boundaries, but things like place, district and county.
Where we see them, we will remove the
source=PGStag, which was from an earlier coastline import that needs to be cleaned up. We received a message on the India coastlines project requesting this, and it is commonly done in other coastline improvement edits.The team will use imagery and data sources below as needed. When in doubt, the team will use the existing tags and data which are used locally. The history in JOSM (ctrl-H) identifies what previous mappers added and their notes and/or explanations regarding changes made. This history can also show if a previous mapper has visited that area or has expert knowledge or sources.
We have also messaged talk-is to get feedback and suggestions about the project.
Our team uses the hashtag #adt (for Apple Data Team) for our edits.
Area of Focus
Iceland
Tools
The team will use JOSM for completing the task. JOSM has validation warnings for road networks and other possible issues that are important to prevent improper changes.
Sources
The team will apply image offsets as needed.
Changeset Comments
The team will provide changeset comments that are in compliance with OSM changeset guidelines.
Where needed, the team will tag corrections with
review_requested=yesso the local community can double check them.Error Detection
The team will check for errors visually and using JOSM validation warnings prior to committing the changeset.
In addition, the team will review its work in accordance with validation guidelines such as the OSM Wiki and LearnOSM.
