photogrammetric mapping
Photogrammetric mapping is the science of using overlapping aerial or drone imagery to create accurate 2D and 3D maps of the Earth’s surface. By analyzing the geometry between multiple images, photogrammetry reconstructs spatial data to generate orthophotos, elevation models, 3D models, and vector maps. At Thinkaerial, we specialize in delivering precision photogrammetric mapping services using cutting-edge software and drone technology to support industries ranging from construction to environmental monitoring.

Master Process Which We Follow
1. Flight Planning & Data Capture
Plan aerial or drone missions with optimal image overlap.
Capture high-resolution geotagged images using professional drone platforms.
Maintain consistent altitude and lighting for uniform data quality.
2. Image Alignment & Tie Point Generation
Import imagery into industry-standard photogrammetry software.
Automatically detect tie points across overlapping images.
Perform bundle adjustment to align images and optimize camera positions.
3. Dense Point Cloud & Mesh Generation
Generate a dense point cloud representing 3D surface details.
Build a textured 3D mesh for visualization and further modeling.
4. DSM/DTM & Contour Creation
Create a Digital Surface Model (DSM) and filter to generate a clean Digital Terrain Model (DTM).
Extract accurate contours for topographic and engineering uses.
5. Orthophoto Production
Orthorectify and mosaic images to produce a georeferenced, high-resolution orthophoto.
Ideal for mapping, surveying, and planning applications.
6. Feature Extraction & Vector Mapping
Digitize features like roads, buildings, and land boundaries.
Create GIS-ready vector layers (SHP, DXF, KML) for project integration.
7. Quality Assurance
Perform accuracy checks using GCPs or survey-grade control points.
Ensure visual clarity, spatial accuracy, and data consistency.
8. Export & Delivery
Deliver complete map products in formats like:
Orthophotos (GeoTIFF, JPEG)
DSM/DTM
LAS/LAZ point clouds
Contours and vectors (SHP, DXF, KML)
