While commercial map providers like Google, provide map data in local Indian languages, the local language labels are usually transliterated from English, resulting in errors. OSM, Wikidata and Wikipedia platforms provide a way to improve the local language maps leveraging multilingual labels through Wikidata identifiers on OSM, through semi automated updates. For good quality maps on Wikipedia and OSM, the Wikidata location needs to be accurate and Wikidata identifier should be uniquely mapped to the actual OSM geometry. I worked on removing the mismatches for villages of a district in Andhra Pradesh. I have documented my experience as clearly as possible, so that even users with less programming and tools skills can contribute to the work. As an example, identifying and fixing errors in Wikidata location is given below.

I did lot of contribution data analysis on Wikipedia. I wanted to do similar thing for OSM. Finally, here is my first analysis. I downloaded the fuel outlets data as of 2023-07-07 from OSM in Andhra Pradesh using overpass-turbo query. I used google sheets to analyse the data. Here are some results.

I added 52 fuel filling stations which is 11.5% increase over earlier count of 451 across Andhra Pradesh. I spent about 10 hours logging the points of interest (POI) and another 10 hours updating them. Here is my backstory or how-to-do guide. I have been an OSM mapper from 2015, having learnt basics from PlaneMad and received mentoring from Heinz Vieth. I have been mapping occasionally about my neighborhood and places that I visit. I also installed Osmand on my smartphone and explored its navigation and trip and POI recording features. In my recent trip to my native state, I tried to record road side fuel filling stations as I drove on the roads as a passenger in car or bus. I used josm to update the OSM.
