Case Studies
Technical reports on AG2I's independent geospatial processing — aerotriangulation and orthorectification benchmarked against manufacturer reference solutions, automated HD-map feature extraction from imagery and HD-map vectors, and product-geometry references characterising delivered survey products.
Fully Independent Aerotriangulation of a Vexcel UltraCam Dragon 4.2 Block
A full Dragon 4.2 five-head block (Graz, 350 exposures / 1,750 frames), aerotriangulated independently from the raw GNSS/IMU trajectory and event log — not the manufacturer's orientation. Check-point RMS 0.035 / 0.069 / 0.069 m (3D 0.103 m) on 10 held-out points; image RMS 1.31 px. Delivered natively into UltraMap as a drop-in substitution.

The AG2I Voxelite™ — an orthophotograph fused with its own elevation into a four-band (R,G,B,Z) gap-free surface — carries a known, control-based accuracy, so it serves as a certified control surface. Disparate datasets, an HD-map vector set and an uncontrolled mobile-LiDAR survey, are registered to it with OpenLineWorks and inherit its accuracy; the whole scene moves together into one conformed, certified frame. Control transfer has closed 1.18 m and 14.8 m gross misregistration onto a high-accuracy reference.

On a precisely aerotriangulated Vexcel UltraCam Dragon block, OpenStereo's multivantage viewer forms a stereo model from any two frames — including oblique pairs — so building facades are measured directly in 3D. Image σ₀ 0.64 px; the floating mark closes to the DSM at ΔZ 0.00 m.

AG2I is a mapping company built as software — an engineering division that builds the suite, a production division that runs it, an orchestrator that plans, and a first-class verifier that gates every stage on measured accuracy. Capacity grows by adding agents and machines, not by hiring; throughput becomes a function of compute. The same manifest expresses any configuration, at any scale.

AG2I runs production as a coordinated team of agents — an orchestrator, deterministic specialist workers, and a first-class verifier over a task DAG and shared blackboard. A tested implementation runs a production line end to end: 6× parallel fan-out, an adaptive bundle-adjustment recovery (σ₀ 1.42 → 0.64), and a 0.25 m QA gate. LLM at the edges, deterministic core.

A road-marking training set built with zero manual annotation — HD-map vector layers projected onto a 0.076 m true-orthophoto yield 15,000 chips across 26 classes; a four-block CNN attains top-1 58.6 % and 56–95 % on whole road scenes. A controlled ablation isolates chirality: a 4×4 spatial head raises top-1 49.7 % → 58.6 % and right-arrow recall 28 % → 65 %. The OpenFeatureX harvester + FeatureCNN.

UltraCam Condor 4.1, Gleisdorf (public dataset). Image σ₀ 0.93 px vs the manufacturer's 1.87 px; fitted-control RMS 0.044 / 0.042 / 0.053 m vs 0.152 / 0.242 / 0.096 m; AT-driven orthophoto co-registering to the factory orthophoto at NCC 0.95, ≈0.05 m absolute at control.

UltraCam Condor 4.1, Gleisdorf (public dataset). The Level-03 PAN, RGB, CIR and 270° products share one exterior orientation per exposure and are perspective frames, not orthophotos — frame fit 2.4 px vs the world-file's 50 px (≈18 m); PAN and colour co-register to ≈0.08 m.

A gap-free 8 cm DSM/DTM/DTMOrtho coastal set in UTM 31N (DTM mean 2.2 m, DSM to 49.5 m, nDSM max 45.2 m), with a bridge-removed DTM variant carving decks from the terrain (1.84 m maximum removal) so the orthophoto drapes continuous water beneath.
