I will create gis ready orthomosaic, dem and 3d models from drone photos
Alexis Flores H
About this gig
Processed with geoscientific precision not just automated stitching.
I turn raw drone imagery into professional geospatial deliverables: georeferenced orthomosaics, digital elevation models (DEM), and 3D textured models built to integrate cleanly into your GIS or CAD workflow.
Drone image acquisition is not included; you provide the aerial imagery and I handle all photogrammetric processing.
Supported CRS/Datums: WGS84, UTM (any zone), NAD83, State Plane, and local/regional datums on request.
As a geologist with hands-on GIS and photogrammetry experience, I work with QGIS, ArcGIS, Agisoft Metashape, and Pix4D for surveying, terrain analysis, construction monitoring, or environmental studies.
What you get:
- Georeferenced orthomosaic map
- Digital Elevation Model (DEM)
- 3D textured model / point cloud
- Clean, structured, ready-to-use files

I'm a geologist based in Chile specializing in GIS analysis, hydrological modeling (HEC-HMS, HEC-RAS), and geological hazard assessment (debris flows, landslides). I work with drone photogrammetry, geospatial data processing, and Python-based automation for large datasets. My background blends academic research in geohazards with consulting experience in environmental baseline studies and field-to-office delivery. I use QGIS, ArcGIS, and RTK/UAV survey equipment.

FAQ
Do you fly the drone and capture the images?
No, I don't provide drone flight or image acquisition. You send me your existing aerial photo set, and I handle all the photogrammetric processing and geospatial deliverables.
What file formats will I receive?
Orthomosaics and DEMs are delivered as GeoTIFF, and 3D models as OBJ or PLY. I can adjust formats to match your GIS or CAD software if needed — just let me know before ordering.
What software or drone photos work best for this?
Any drone photo set with good overlap (70-80% front, 60% side) works well. I process the images using Agisoft Metashape and Pix4D, then deliver results in QGIS/ArcGIS-ready formats.
Can you remove trees and vegetation to get a bare-earth terrain model?
Yes, ican generate a vegetation-filtered DTM (bare-earth) using classification techniques, which is critical for accurate slope, drainage, and geological interpretation.
How many drone photos are included per package?
Basic Package: Processing of up to 200 photos (ideal for small plots/sites). Standard Package: Processing of up to 500 photos (medium-sized surveys). Premium Package: Processing of up to 1,000 photos (large sites and full technical deliverables). If your project exceeds 1,000 photos, please send
What if I have a custom project size, GCPs, or specific accuracy requirements?
Every survey is unique. If you have a dataset with Ground Control Points (GCPs), specific coordinate systems (CRS/Datum), or large volume datasets (1,000+ images), please contact me before ordering. I will review your dataset and send you a custom offer suited to your project’s exact specifications.
