Proposal Data Conversion Work Plan Import Guide Progress

Addresses Import describes a proposal being developed to import data provided by the Rio Branco City Council in Brazil. If you want to participate actively go to the import guide. If you want to know all the details of the proposal, read on.

It is important to note that this import is semi-automated, due to the nature of the available data, that is, it is not possible to import the data all at once. This requires a higher user experience, taking more time to perform the import and the necessary adjustments for OSM upload.

Goal

This project aims to manually conflate addresses provided by the city council.

Schedule

  1. December 2022: Preparation of the import proposal in the wiki and data fix/validation.
  2. January and February 2023: Disclosure in talk-br list (in Portuguese) and on the new forum, discussion in the OSM Brazil Telegram group, and submission of the import proposal to the Imports List.
  3. future: Annotation in the Import Catalog.
  4. future: Import beginning
  5. future: Import ending

Data to be imported

Data description

The data is provided by the Rio Branco City Council. The data is available in SHP format. The data, originally, refers to the tax parcels, that contains many information such as address (the only data that matters for this import). The data is of a good quality (positioning and correctness).

Data source

The data was provided by e-mail, but can be accessed through this link.

License of access and use

The OSM community has explicit permission to use the Rio Branco City Council data, according to the user ThierryAJEAN and the city council e-mail exchanges.

Size of the data set

The original shapefile is 34 MB, accounting for a total of 106,493 parcels (before any cleanup).

Data conflation

This is the strategy to avoid conflicts with existing data:

  • If possible, initially a filtering must be made in Overpass Turbo, observing addresses that are already mapped in the OSM, and then remove those addresses from those provided by the city council. If not possible, a manual check is mandatory.
  • In principle, the addresses that are already mapped in the OSM must remain, as recommended. Eventually, if they are in significant disagreement, they can be complemented by those from the city council layer, maintaining the OSM tagging data. The total replacement comes as a last case, to not lose the history of the previous address in the OSM.

Data import

A more detailed tutorial is available on the Import Guide tab.

However, given that there may be problems with imported data that require manual intervention, a manual import is planned with a review of each object to be imported.

Team

Work plan

The volume of data to be imported is very large. Therefore, it is proposed to carry out the work by regions, starting from the smallest to the largest. It is thought to carry out the division by neighborhoods, using the number of addresses as a parameter. More details are shown in the Work Plan tab.

Regression plan

If necessary, the changes will be undone using the JOSM/Plugins/Reverter plugin.

Acknowledgments

We would like to thank the contribution of the Rio Branco City Council in providing the data. We also thank Mr. Thierry Jean at Address for All for making the original file available to us. Finally, we acknowledge and appreciate the financial support given to us by OpenCage, which allowed us to carry out this import.
