Data merge workflow

Workflow / Conflation

The cleaned up data sets will be divided into sections and assigned to the each user based on region.

Every individual user will follow the below instructions:

  1. Install the ToDo list and the OpenData plugins in JOSM
  2. Load the cleaned csv file into JOSM.
  3. Convert/save the csv file as .geojson/.json or .osm (To be confirmed).
  4. Select all the elements and add to ToDo list.
  5. Go to the first element, download OMS data and check all the attributes of the same - the address, position of the feature and check for another similar feature in the area.
    1. If the feature is already existing in OSM then add the missing attributes.
    2. If there isn't a feature and the address of the element is correct then copy the same into the OSM layer.
  6. Repeat with all the elements on ToDo list, verify with JOSM validator and upload the changes with the import changeset tags.
