Data Improvements in Malaysia #150

Open awisemanapple opened 4 years ago

awisemanapple commented 4 years ago

Task Description

This task outlines work to improve the map data in Malaysia. We plan to focus on improvements to the road network first, and later we may do some edits to other feature types if necessary, such as buildings, addresses, water, and land use and other related polygonal features. We will message the local community and get feedback and suggestions for this project.

Improvements that will be addressed include the following:

Mapping Guidelines

The team will follow OSM and local policy, along with any other guidelines as appropriate. We also posted on the OSM Malaysia forum about the project.

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 administrative boundaries, in which case we will adjust both if appropriate.

Where we see them, we will remove the source=PGS tag, 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-my to get feedback and suggestions about the project.

Our team uses the hashtag #adt (for Apple Data Team) for our edits.

Area of Focus

Throughout the country.

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.

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 validation guidelines

Ferry data

Apple is releasing data on ferry terminal and line information missing from OSM in Malaysia. This contribution is made available for use under the OpenStreetMap ODbL license. The data includes ferry terminals with names of ferry lines, whether the ferry is for cars, and the direction of the ferry, if applicable. We will confirm that the ferry exists and the terminal location is correct, and if missing we will add those to OSM and estimate the ferry route. The data includes starting and ending points at ferry terminals but not the specific routes between them. When we use the data we will cite it in the OSM changeset source tag.
