We developed an AI-based workflow combining DeepLabV3 and Medial Axis Transform to automatically extract river centerlines and estimate river width from Sentinel-1 SAR imagery.

✅ F1 Score: 0.933
✅ Tested on 4 major river systems
✅ Estimate centerline and width estimation

🌍 Field Surveying, GIS, and Remote Sensing in Action

Here’s a quick look at some of the tools and techniques I’ve used in real‑world geospatial and environmental projects. From setting up total stations and GNSS receivers to UAV flights and river surveys, every workflow captures the intersection of technology, precision, and field experience.

Whether it’s mapping river systems, collecting high‑accuracy ground control points, or integrating UAV imagery with GIS, these moments reflect the hands‑on side of geospatial science.
✨ Topics Featured:
📌 Total Station Surveying
📌 GNSS/GPS High‑Precision Positioning
📌 UAV (Drone) Mapping
📌 Environmental Fieldwork
📌 River & Landscape Surveying
📌 GIS + Remote Sensing Applications

If you enjoy learning about GIS, UAVs, surveying, and earth science workflows, make sure to follow along — more tutorials and field stories coming soon!

🌱 Welcome to the Geo Mentorship Initiative

Empowering underserved, unheard, and underrepresented youths to find guidance, confidence, and a clear path forward.

For many students, especially first‑generation, international, national, and minority youth, life comes with challenges most people never see. No mentors. No guidance. No direction. No one to say, “You belong here.”

That’s why I started this mentorship program.
✨ My mission is simple:
To support young people who feel lost, unseen, or unsure where to begin — academically, personally, or professionally.
Whether you want help with:

🎓 Education & career planning
🌍 Studying abroad
🗺️ GIS, UAVs, Remote Sensing, Surveying, Geoinformatics, Geomatics Engineering, Fluvial Geomorphology, STEM
💬 Building confidence, communication, and purpose
📚 Scholarships, internships, and opportunities
🤝 Or simply having someone to talk to who understands your journey

…I am here to help you and me grow.

Testing My DIY Sense Box to Find the Perfect Photography Spot!

Today I experimented with a small “sense box” made from different sensors — a light sensor, wind sensor, humidity + temperature module, and even a distance sensor. Inspired by environmental monitoring kits, I wanted to see if a simple sensor setup can help us choose the best place to take photos outdoors.
The idea was simple:
✨ More light = sharper photos
💨 Less wind = more stable shots
🌡️ Balanced temperature/humidity = less lens fog
📏 Clear surroundings = clean composition
Using these sensors, I mapped out small areas and compared the readings. Surprisingly, the “best” photo spot wasn’t the one that looked great to the eyes — the sensors helped reveal real environmental conditions that affect photography quality.
Would you try something like this?
