Client feedback

What clients say

“M. Mashrur Zaman has processed over 400,000 UAV images into survey-grade orthomosaics, DSMs, and DTMs across 15 municipalities for our ADB-funded coastal infrastructure program and brought that same precision to a specialized runway crack detection study—on schedule, and to a standard we could hand straight to our clients.”

About

Urban planner turned geospatial specialist

Portrait of M. Mashrur Zaman, GIS and photogrammetry specialist based in Dhaka

I'm a full-time freelance geospatial specialist based in Dhaka, Bangladesh, working with clients in the US, Europe and Asia. My background bridges Urban Planning (BSc) and Geographic Information Systems (MSc), with 7+ years of production work in remote sensing and photogrammetry.

I run large drone photogrammetry programs on a dedicated multi-machine setup, process LiDAR and point clouds, and build cadastre and utility datasets end to end, from raw data to client-ready deliverables. More and more of that work runs on Python automation, which keeps results consistent and turnaround short.

I work remotely, overlap comfortably with US business hours, invoice in USD, and treat every project like it's my own name on the deliverable — because it is.
