About Me

I am Brazil Singh, an open mapping advocate, digital innovator, web developer, and community leader from Bangladesh. As an Open Mapping Guru at the Open Mapping Hub Asia-Pacific, I equip communities with practical and impactful mapping skills. I play a key role in managing social media for the OSMF, and actively contribute as a volunteer in the OSMF Local Chapters and Communities Working Group (LCCWG).

As a dedicated mapper, trainer, community organizer, and advocate, I have worked with the OSM ecosystem at local, regional, and international levels. From mapping in flood-affected areas of Thailand to mentoring YouthMappers across Asia and beyond, to volunteering with HOT and the OSMF Communication Working Group, I have seen firsthand how collaboration can create meaningful impact.

What HOT means to me

We know OpenStreetMap is one of the most powerful and collaborative geospatial databases in the world. It relies on contributions from everyday users, developers, humanitarian workers, and mapping enthusiasts to keep data accurate and up to date.
But like any open data project, OSM faces issues. And understanding the types of issues we encounter is essential to maintaining map quality. One simple and effective way to think about OSM data problems is, to divide them into two broad categories:

1. Existing Issues: Errors in the Map

These are problems that exist within the current OSM data. The features are already mapped, but something about them is incorrect, inconsistent, or outdated.

Common examples:

• Incorrect tags: A residential road tagged as a motorway.
• Geometry errors: Buildings that are misaligned, roads that don’t connect properly, or rivers overlapping with buildings.
• Outdated features: A shop that closed years ago but still shows up on the map.
• Inconsistencies: Using different tags for the same type of feature in nearby areas (amenity=school vs. building=school).

2. Non-Existing Issues: Missing from the Map

These are features or data that should be on the map but are completely absent. The problem here is not about fixing what’s wrong, it’s about recognizing what’s not there at all.

Common examples:

• Unmapped buildings visible in satellite imagery.
• New roads or paths that haven’t been digitized.
• Missing POIs like schools, hospitals, or shops.
• Lack of metadata such as opening hours, accessibility info, or addresses.

Why This Distinction Matters

Thinking in terms of “existing” vs. “non-existing” issues helps:

২০২৪ সালের OpenStreetMap ফাউন্ডেশন মেম্বারশিপ ক্যাম্পেইনে স্বাগতম!

আজ, ওপেনস্ট্রিটম্যাপ ফাউন্ডেশন (ওএসএমএফ) বোর্ডের সদস্যরা এবং বেশ কয়েকটি ওএসএমএফ ওয়ার্কিং গ্রুপের সদস্যরা একটি বিশ্বব্যাপী ওএসএমএফ সদস্যতা প্রচারাভিযান শুরু করছে। যেখানে ওএসএমএফ সদস্য নেই বা খুব কম এমন অঞ্চলে ওএসএমএফ সদস্যতা বৃদ্ধি এবং বৈচিত্র্যময় করার লক্ষ্যে।

আপনি এই মানচিত্র থেকে দেখতে পাচ্ছেন, এরকম অনেক অঞ্চল রয়েছেঃ ওএসএম একটি বিশাল, বিশ্বব্যাপী ম্যাপার, পেশাদার জিআইএস, কমিউনিটি বিল্ডার, ডেভেলপার, ইঞ্জিনিয়ার, প্রশিক্ষক ইত্যাদি দ্বারা নির্মিত হওয়ার জন্য পরিচিত, যা ম্যাপের অস্তিত্বের বিগত বিশ বছরে তাদের স্থানীয় জ্ঞানে অবদান রাখে এবং উন্মুক্ত এবং বিনামূল্যে ভূ-স্থানিক ডেটা বজায় রাখে।

OSM ফাউন্ডেশন, OSM এর প্রযুক্তিগত সিস্টেম এবং ডেটা তত্ত্বাবধান করে OSM তৈরির পরিচালনা এবং সমর্থন করে। এটি দীর্ঘমেয়াদী কৌশল এবং মানচিত্রের মঙ্গল পরিচালনা করতে সহায়তা করে।

সুতরাং, OSM ফাউন্ডেশনের সদস্যপদ তার সম্প্রদায়ের বিশাল বৈচিত্র্যের প্রতিফলন হওয়া খুবই গুরুত্বপূর্ণ।

Their actions, no matter how small, can set off a chain reaction of positive transformations within the community.

This, in turn, may inspire individuals to become more engaged and invested in the betterment of their community.
