Data Improvements in Mexico #122

Task Description

This task outlines work to improve OSM data in Mexico, such as the road network, coastlines and inland water, and land use and land cover polygons -- remove duplicates, correct geometry, fix incorrect tags and other similar things.

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 have also emailed talk-mx and the OSM Forum for Mexico to get feedback and suggestions 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 the imagery and data sources specified below as needed for mapping in the country.

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.

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

I am glad SandyCreek pointed me to this group. I’ve been mapping México on OSM since 2008
