Workflow

Overview

###Requirements

###Process

  1. Reserve an area here on the tasking manager
  2. Click "JOSM" button, this will open the area in JOSM and load up existing OSM data
  3. Click ".osm" button, this will open new buildings and addresses in a separate layer
  4. Manually copy new building and address data into OSM layer
  5. Resolve conflicts (see merge rules below)
  6. Run JOSM validation
  7. Resolve validation errors
  8. Upload to OSM
  9. Mark the task as done - but not as validated - here on the tasking manager

Merge rules

The upload process is fairly straightforward, the most complex part is resolving conflicts between existing data and to-be-imported data: there are plenty of existing buildings in the New York City OSM map. Where they conflict with new data, a decision needs to be made. Here are a couple of simple rules to aid this decision:

Keep the best data

A priori, there is not a preferred dataset. Compare building footprint quality and decide on a case by case basis, keeping the better dataset. In doubt, keep the OSM data.

Do not toss attribute data

In case you decide to toss existing OSM data, do not toss existing attribute data, but copy it to new geometries.

Resolve preexisting conflicts

In case you run into preexisting conflicts that might not have to do anything with building or address manipulation, resolve them before uploading.

Questions?

If a question arises, please open a ticket on osmlab/nycbuildings, and add a screenshot if possible.
