Overview

From Raw Imagery to Intelligent 3D Layers

AAMS combines high-precision photogrammetry, airborne and mobile LiDAR, and 3D mapping in a GeoAI-enhanced GIS workflow to deliver survey-grade spatial intelligence. We produce accurate true orthophotos, digital surface models (DSMs) and digital terrain models (DTMs), served through advanced GIS platforms for seamless visualization and analysis.

Powered by GeoAI, automated feature extraction, semantic classification and change detection turn these datasets into intelligent 3D layers for infrastructure, urban planning and digital twins. The result is faster decisions, smarter asset management and data that is ready to use the moment it is delivered.

What we deliver

Core Capabilities

Four connected stages take data from aircraft, drone and vehicle sensors to analysis-ready GIS layers, with GeoAI automating the heavy lifting.

01 / Photogrammetry

Aerial Triangulation & True Orthophoto Production

Every photogrammetric project begins with rigorous aerial triangulation tied to surveyed ground control, giving the whole image block a precise geometric foundation. From there we produce georeferenced orthomosaics and true orthophotos with uniform scale across the project area.

True orthophotos remove building lean and hidden areas, so tall structures and dense urban districts can be measured accurately. They become the base map for cadastral work, planning, design and asset inventories.

Digital Surface & Terrain Models

We generate digital surface models (DSMs) that capture everything on the ground, and digital terrain models (DTMs) that represent the bare earth beneath vegetation and structures. Breaklines and LiDAR data are used where needed to hold engineering accuracy along roads, channels and embankments.

These elevation products drive contour mapping, cut-and-fill and volume calculations, drainage and flood studies, and line-of-sight and visibility analysis for major developments.

Automated Feature Extraction & Semantic Classification

GeoAI models identify and vectorize buildings, roads, vegetation, utilities and other features directly from imagery and point clouds, and classify LiDAR data into ground, buildings, vegetation and infrastructure classes. What once took weeks of manual digitizing can be produced consistently in a fraction of the time.

Change detection compares new and historical datasets to flag new construction, encroachments and surface changes automatically, so asset registers and planning records stay current.

3D GIS Layers, Visualization & Digital Twins

Finished datasets are structured as intelligent 3D layers and served through advanced GIS platforms, from orthophotos and elevation models to 3D building models and classified point clouds. Clients can view, query and analyze their data without specialist software.

Because every layer is georeferenced and attribute-rich, the same data supports infrastructure design, urban planning, asset management and the development of city and facility digital twins.

FAQ

GIS & Photogrammetry Questions, Answered

Not sure which approach suits your project? Our team can recommend the right method, equipment and deliverables.

What is a true orthophoto and why does it matter?

A standard orthophoto corrects for terrain, but tall buildings can still appear to lean and hide what is behind them. A true orthophoto corrects for buildings as well, so every feature sits in its correct position and can be measured accurately. This matters most in dense urban areas and for projects that need precise measurements of structures.

What is the difference between a DSM and a DTM?

A digital surface model (DSM) represents the top of everything, including buildings and vegetation. A digital terrain model (DTM) represents the bare ground with those features removed. DSMs suit line-of-sight and urban analysis, while DTMs are used for engineering design, drainage and flood modelling.

What is GeoAI?

GeoAI is the use of artificial intelligence and machine learning on geospatial data. We use it to extract features such as buildings and roads, classify point clouds and detect change automatically, which makes large mapping projects faster and more consistent than manual methods.

Should I use photogrammetry or LiDAR?

Photogrammetry excels at visual detail and produces orthophotos and textured models, while LiDAR penetrates vegetation, maps bare-earth terrain and can be captured day or night. Many projects combine both. Compare them in our guide to airborne photogrammetry vs LiDAR.

What file formats do you deliver?

We deliver GIS-ready data in standard formats including GeoTIFF orthophotos and elevation models, LAS/LAZ point clouds, and vector data for CAD and GIS platforms. Formats, coordinate systems and specifications are agreed with you at the start of each project.

Can you process data captured by another provider?

Yes. We can process, classify and enhance existing aerial imagery, LiDAR and point cloud datasets, including quality control, feature extraction and conversion into GIS-ready layers. For new data capture, see our aerial mapping and LiDAR survey services.
