Project goal

The data to be imported is from Stears Open Data. The data import to be done is to contribute valuable data to OpenStreetMap by importing data on ferry facilities and routes in Lagos, Nigeria. The data was collected via a field survey, and the goal is to create a comprehensive map of publicly and privately operated ferry routes in Lagos to support wide range of stakeholders, including transport planners, humanitarian organisations, and the general public. The project seeks to encourage more use of water transportation and reduce road congestion.

Tagging Plan

The Tagging Style utilised were extracted from the OSM wiki tag for piers (https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpier), which was utilised for the Jetties, and the Ferries (https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dferry_terminal). Other tags incorporated were searched from different sections of the OSM Wiki (https://wiki.openstreetmap.org/wiki/Tags). Here are some tags ( keys and values ) utilised for the data import:

Jetties

  1. admin_name=
  2. operational_status
  3. amenity:note
  4. boat:rental
  5. amenity=ferry_terminal
  6. operator=public
  7. operator= private
  8. cargo = passengers
  9. public_transport = stop_position
  10. source = survey
  11. source:name = name
  12. survey date

Ferries

  1. operation = private
  2. operation = public
  3. operational_category = high_frequency
  4. operational_category = low_frequency
  5. operator:name
  6. cost:note
  7. interval:note
  8. opening_hours:note
  9. public_transport
  10. additional_note
  11. source
  12. source: name

Changeset tag

The following changeset tags will be utilised for the data import and validation: #stearsopendata #WNAH #HOT #2025

Data transformation

  1. The original file came in JSON.
  2. The file was then converted to Excel, CSV and Geojson format.
  3. The Excel files were used for manual editing to clean the data and ensure it was tagged to OpenStreetMap Tags
  4. The Excel files were converted to CSV to import into QGIS.
  5. In QGIS, the cleaned CSV file was brought in to be merged with the Geojson file that had the locational data for the jetties.
  6. The file, saved, was exported as Geojson and imported into the JOSM Software
  7. The JOSM software was utilised for checking edits, tag errors flagged, and then imported the data to OpenStreetMap.
