Merge Entities

  1. Create csv file in root and populate
    To merge duplicate entities, we make use of the add-redirections command. For this, you will need to have a csv file with the entities you want to merge (we’ll name it entity-merge.csv for this explanation) . Imagine that a conservation-area has duplicate entities, one with the entity number 3032307 and the other with number 3033940. We want to combine both together as they refer to the same entity. We will essentially be redirecting references of 3032307 to 3033940

    The csv file would look like this:

entity_source, entity_destination
3032307,3033940

  1. Run add-redirection script

    Assuming the collection name is ‘conservation-area’, run the command in a virtual environment like so:

digital-land add-redirection ./entity-merge.csv -p ./pipeline/conservation-area
  1. Check result

The command in step 2 should have added an entry in corresponding pipeline old-entity.csv file like so:

old-entity,status,entity
3032307,301,3033940

Once verified, the updated old-entity.csv file should then be pushed and merged.
