About this gig
Transform your drone photos into accurate maps & 3D assets
I convert drone photos into accurate maps and 3D assets for engineering, construction, and environmental projects. I work with Pix4D, Metashape, ArcGIS Pro, and QGIS, integrating GCPs/RTK for reliable accuracy. Clear deliverables, tidy layers, and honest QCevery time.
Have raw drone/UAV images? Ill professionally process them into georeferenced orthomosaics, DSM/DEM, point clouds, contours, and textured 3D modelsready for GIS, CAD, and planning workflows.
What I Deliver
- Orthomosaic (GeoTIFF): high-resolution, georeferenced aerial map
- DSM/DEM: surface & bare-earth elevation models (GeoTIFF)
- Point Cloud: LAS/LAZ, classified on request
- Contours: CAD/GIS-ready (SHP/DXF/GeoPackage)
- 3D Model: textured mesh (OBJ/FBX/PLY) + snapshots
- Report: processing summary, RMS error & accuracy notes (with GCPs/RTK)
Common Uses
- Site planning, earthwork, cut/fill analysis
- Construction progress, asset documentation
- Forestry & environment, watershed & slope mapping
- Agriculture health mapping (optional indices)
- Real estate visuals, marketing-ready overviews
Accuracy & Workflow
- Recommended overlap: 80% frontlap & 7075% sidelap
- Coordinate support: W

I’m S M Sium, a passionate GIS Consultant with extensive expertise in geospatial analysis, web GIS, and remote sensing. I’ve had the privilege of contributing to major projects in Bangladesh like Border Road Development, Marine Drive Shore Protection and the Cox’s Bazar Master Plan. My focus is on delivering precise, innovative GIS solutions that empower better decision-making in urban planning, infrastructure,and the environment. I also offer tailored GIS training to help teams build valuable local expertise. Let’s collaborate to bring your ideas to life with cutting-edge geospatial solution.
FAQ
Q1: What if my images have low overlap?
I’ll assess feasibility first. If coverage is marginal, I’ll propose a reduced AOI or ask for re-flights to maintain quality.
Q2: Can you handle heavy canopy or water surfaces?
Yes, with caveats. Vegetation and water can reduce tie points; DEM quality may vary. I’ll apply filters and classification, and include notes in the report.
Q3: Can you use my GCPs or RTK?
Absolutely. Provide coordinates, CRS, and marker visibility. I’ll include an accuracy summary (RMS, checkpoints).
Q4: What formats do you deliver?
GeoTIFF (mosaic/DSM/DEM), LAS/LAZ (point cloud), SHP/DXF (contours), OBJ/FBX/PLY (3D mesh), PDFs/PNGs for maps/legends, and a short report.
Q5: Can you do contours at a specific interval?
Yes—common intervals are 0.25 m / 0.5 m / 1 m (or 1 ft / 2 ft). I’ll smooth intelligently and keep hydrology-safe breaks.
Q6: My files are huge—how do I share?
Share via Google Drive/Dropbox/WeTransfer. I’ll return organized deliverables with a simple folder structure.
