Until recently, I mainly used the opening_hours evaluation tool to quickly generate valid OSM opening hours. However, it often requires some manual work to simplify the syntax afterwards.



I have created a tag, diet:excipient_free=* , which is about finding clean supplements, i.e., without harmful ingredients that can make us infertile, inflamed, obese or even epileptic.

For example, whenever we look for magnesium (bis)glycinate, we want one thing, but many so-called “magnesium” supplements come with a lot more ingredients that might reduce the price, or enhance the appearance, but of course, at a cost; to hurt and make us need another supplement to compensate with the side effects. (Maybe they should rename those “magnesium” supplements to corn syrup supplements instead.)

Almost if not all of those ingredients fall into one category, excipients. Let’s use diet:excipient_free=* on pharmacies and nutrition supplement stores to promote a healthier future without dyes, fillers, flavorants, preservatives and other inactive ingredients that can cost us our health.


OpenStreetMap old timers know about the infamous 2009 TIGER import of road data in the US that continues giving to this day.


3 March 2026: Writing this a Missing Maps “London” remote meeting, realizing that I’d never written a OSM diary about the research I did within the ecosystem. I’m so late! But I’d love to still write this down.


I started a new wiki talk page discussion on the conflicting/controversial usage of the wetland=tidalflat tag regarding implied and explicit surface types:



Every map tells a story.
Some stories are drawn with roads and buildings. Others are written through people, voices, and lived experiences.


Nimman Road, Chiang Mai(Thailand) is a well-mapped, high-traffic corridor. It scores a B on network density: good intersection frequency, reasonable block lengths.

A few months ago, I worked on a new project: the OSM Tagging Schema MCP — a Model Context Protocol (MCP) server built for AI assistants and LLM applications that interact with OpenStreetMap tagging data.



finding myself to osm was something I couldn’t understand at the time. Now with an open eye, in my field of water engineering introduced to geographical information system. I love it here my journey begins now mapping take me overseas. 😊


I successfully put Novato Baylands Point Blue Conservation Science as a pin on the map. However, I have not had success with editing the directions that maps provides to get you to the site. The directions still route you past the facility, rather than stopping right at the facility. They should tell you to go down Aberdeen Rd, and then the location is on your right. Thanks for any assistance with editing the route.


I’m new to editing OpenStreetMap, so this is my first change! I noticed that most neighbourhood areas in Lethbridge, my local city, don’t have a name shown in OSM. However, they’re all neatly shown on an official 2024 map from the government of Lethbridge, so I used it as a source. I did notice that some areas are already named in other ways, but I couldn’t find the item that holds the name. This induced visual clutter by doubling some names (those of the industrial parks, Copperwood, and seemingly Paradise Canyon), but I still added the names to the neighbourhood areas for consistency anyways. If anyone around knows how to get rid of this without removing the naming consistency, it would be great if this slight issue could be resolved. I haven’t actually tested the map yet, since I just uploaded the edit, but if what I’m describing is actually a problem, please help? Anyway, I intend on updating and adding a lot of things to Lethbridge (like adding addresses and new buildings) in the near-ish future, so it’d be fun to get to know the local OSM community.



I have a large set of photographs I made while running. They are geotagged, as I took them with my phone camera. The compass direction is completely unreliable, but lat/lon is more trustworthy.


A few quick notes on some changes I made to OSM based on local knowledge.

  • Changed the point for the Riverside Centre building to reflect that it is now a Builder’s Corner hardware store.

  • Added a point for the nearby Hole in the Wall Centre

  • Defined an area for the Somerset Lofts apartment complex and added some details for it.


Ive recently begun contributing street-level imagery on Mapillary and Panoramax in my local area. I figured that my dash cam was already recording anyway, so if it could be of use to anyone, why not share it?



  • I spent some time today improving the map data in my local area using the iD editor. As a local, I noticed that several roads were untracted

  • added roads but i got confused while selecting presets- then i realised the more i do mapping, the better i will get with using presets. Each preset serves a unique purpose.

  • Few weeks ago i spent time mapping my school in my city, i was soo fun- just wish they could use more updated satelite image.



Changeset: 178729012


Today I contributed to OpenStreetMap by improving map completeness in my local area in Bengaluru, Karnataka.

🔹 What I Worked On

Added a missing café using local knowledge Verified placement to ensure it was mapped at the correct entrance location Added appropriate tags including: amenity=cafe name= ##Bean Stop Café

Checked for duplicate entries before uploading

🔹 Mapping Approach

I focused only on verified, ground-truth information and avoided copying from copyrighted sources. All additions were based on direct familiarity with the area.

🔹 Quality Checks

Ensured the point was not placed on the roadway Confirmed correct spelling and capitalization Reviewed surrounding features for consistency

🔹 Objective

The goal was to improve local POI completeness and contribute accurate, structured data to OpenStreetMap. This is part of my effort to make consistent, quality-focused contributions rather than large, unverified edits.



Changeset: 176210161


In this changeset (176210161), I focused on improving building-level mapping by adding missing building outlines and refining structural details using Bing Maps aerial imagery.

The objective of this session was to enhance spatial accuracy and improve map completeness in the area. I ensured that:
  • Building footprints were aligned correctly with satellite imagery
  • Proper geometry was maintained
  • No duplicate structures were created
  • Tagging remained consistent with OSM standards
This edit was completed using the iD editor (v2.37.3), and I requested a review to ensure quality validation and community feedback.

Working on building details helped strengthen my understanding of:
  • Accurate polygon tracing
  • Satellite imagery interpretation
  • Clean data structuring
  • Version control within OSM changesets
I will continue improving structured building data and map quality in Karnataka.


Changeset number is 178690672


Today, I worked on improving map data around Yelahanka Taluku, Karnataka. I updated the official name of Sai Vidya Institute of Technology to reflect accurate real-world information and ensured proper tagging consistency.

In addition to correcting the name, I reviewed campus boundary structure, building tagging, and surrounding infrastructure to avoid duplication and maintain data integrity. I verified that the edits align with real-world sources and OSM tagging standards.

My focus during this session was on:
  • Accurate name correction
  • Structured campus boundary validation
  • Road connectivity refinement
  • POI accuracy improvement
  • Avoiding duplicate objects
This session helped reinforce the importance of precise tagging, version tracking, and reviewing live map data versus cached tiles. I will continue contributing to improving structured geospatial data across Karnataka.


Many people have noticed that publicly available Overpass servers have been suffering from overuse (a typical tragedy of the commons). OSM usage policies generally contain the line OpenStreetMap (OSM) data is free for everyone to use.


Hello! This is my first Diary Entry and I wanted to dedicate it to the Forum Post that I made about the UKs Only (I Believe) ER OUT routes in the case of any emergencies: mainly flooding in this case.


Safe Routes to School is a program designed to help parents encourage their
children to walk and bike to school safely, while promoting healthy engagement.
In some locations, walking or biking to school is a childs only means of getting to school.


About 99% of supplements have garbage in them like seed oils, starch, citric acid or other fillers because most people are too ignorant to read the ingredients labels, let alone realize that ultra-processed pseudo-food is harmful for them in the first place.

I wonder if there is some tag for a nutrition supplements store to state that they offer clean supplements with just one ingredient, just like vegetarian tags, except focused on health rather than ethics.

Maybe diet:raw=* could somewhat apply?




For a while, I was interested in understanding what makes one pedestrian OSM way better than another. I wanted to know if there is some generic way to identify good walking routes from OSM data. I looked at Garmin and Strava heatmaps at first.


I mainly edit OSM based on GPX files from my runs. I use JOSM. I created a simple script to extract a buffered area around my GPX files to make sure I dont accidentally edit parts of OSM I dont intend to. See this Github Gist for the source.
