Customisation for matching wikidata to cities

[bsrinivasa]

The current Wikimama script looks for neighbourhoods around a city for a specified radius and thresholds.

Customisation for matching cities

• Compare list of cities from OSM with list of features which are instances of cities in Wikidata
• Option to vary threshold

Basically, Wikimama tool for cities would be comparing names from both the platform and scores accordingly and derives the difference in distance b/w the co-ordinates from both the platforms.

The threshold would be tweaked based on the initial output from Wikimama.

Here is the customized script for city matching:

To run: node batch-match.js --file input.csv , where input.csv contains the threshold value

@amishas157 rather than having this code in a branch, can you make this an option we can pass to the main script to take what type of feature we want to match?

👍 @geohacker

We should just take the search radius as an option --radius while running the script.

The input could then be either:

• input.csv of a list of locations with lat/lons and an Overpass query.ql to generate OSM features
• input.geojson of OSM features generated from Overpass

@geohacker @amishas157 We might not have a chance to do this again. In this iteration, we would be matching corresponding wikidata entities for almost of the cities in OSM. The only case where we might use this again is when there are new cities added to OSM which do not have wikidata items tagged to it. Should we still make it generic for various types of input?

I think we should, if it's not a huge lift.

The tool was optimised for matching cities. Check out the branch 🎉 . Thank you @amishas157 for quickly building this. 🙂

Tracking further discussion on generic inputs at #13. Closing this ticket. 🚀
