Bad imports/Enugu POI import
This page handles the import of POI in the city of Enugu (Nigeria) according to the Bad imports procedure.
Issues with the data
Lack of data quality
I can't remotely check most parts of the data quality in that city, as I don't know the POI positions, names and other attributes in real-life. However, there are many mistakes against OSM tagging that could be avoided by simply discussing the import better.
Take the tags of node 2455133716
2455133716 as example.
| Key | Value | Note |
|---|---|---|
| BRANCH_NAM | Ogui Road | All these capitalised tags are duplicates of the regular tags |
| CATEGORY_1 | Financial Institution | |
| EASTING | 7.49278 | |
| HEIGHT | 215.100006 | |
| HOUSE_NUMB | 0.0 | |
| LOCATION_A | 3.0 | |
| NORTHING | 6.437721 | |
| NUMBER_OF_ | 1 | |
| POI_ID | POI001572 | |
| POI_NAME | Enterprise Bank | |
| POI_PICTUR | Long link | |
| POI_PICT_1 | Long link | |
| POSTCODE | 400.0 | |
| STREET_NAM | Ogui Road | |
| addr:postcode | 400.0 | I wonder if the postcodes in Enugu are really decimal, also note that this key has also been modified since the import, the old key used "postcode" |
| amenity | bank | Yay, a good tag |
| branch_name | Ogui Road | This should be operator or brand I assume |
| category | Financial institution | This isn't standardised (and implied by amenity=bank) |
| easting | 7.49278 | Duplicating position is unneccesary |
| height | 215.100006 | Height information is nice, but I doubt this was measured up to one µm precise. |
| house_number | 0.0 | Not a standard tag, and are housenumbers decimal? |
| id | POI001572 | No reference to what it means |
| image | long link | Link is broken meanwhile |
| image:url | long link | Duplicate of the image key, and the link is broken |
| location | 3.0 | No idea what this is |
| name | Enterprise Bank | Looks ok |
| northing | 6.437721 | Duplication of position information is unneeded |
| number_of | 1 | No idea what this is |
| street_name | Ogui Road | Should use the standardised addr:street tag. |
Lack of discussion
There is some documentation on the wiki on the Enugu State Routing Project page. But the documentation is very sparse, and there's little discussion
License of the data
The data seems legal to me.
Contacted users involved with the import
- Luchiri changeset 17795004 (achavi, OSMLab)
- mikelmaron who was not involved in this import, but in the related Enugu streets import via OSM PM
Possible fix
None so far
Discussion
When you look at branch_name and name, it seems like the full name is Enterprise Bank Ogui Road. When I compare this with my local situation, this would mean that Ogui Road goes into name and Enterprise Bank in brand or operator. (escada)
