Terrain Visualisation // Commissioned Landscape Interpretation
Terrain FAQ
A plain-English guide to the terrain, LiDAR and AR terms used across Studio Oddscape.

What is LiDAR?

LiDAR uses laser measurements to record the shape of the ground and landscape. It can reveal subtle landforms, earthworks, channels and surface features that may be difficult to see in ordinary aerial photography.

What is a DTM?

A Digital Terrain Model represents the bare earth surface. Buildings and vegetation are removed where possible, allowing the underlying landform to be studied more clearly.

What is a DEM?

A Digital Elevation Model is a digital height model. Depending on the dataset, it may represent bare ground, surface features, buildings or vegetation.

What is a hillshade?

A hillshade is a shaded terrain image created by simulating light across a height model. It helps reveal ridges, hollows, earthworks, drainage lines and subtle changes in landform.

What is a REM?

A Relative Elevation Model emphasises local height differences by reducing broad elevation trends. This can make subtle features such as palaeochannels, earthworks and low ridges easier to read.

What is an Oddscape REM?

An Oddscape REM is a terrain interpretation output produced through the Oddscape Terrain Engine™. It combines relative elevation processing with visual enhancement to make landscape structure more readable.

What is AR?

Augmented Reality places a digital terrain model into your physical space, allowing it to be viewed like a tabletop landscape model on compatible devices.

What is a USDZ file?

USDZ is Apple’s 3D model format for Quick Look and AR viewing on compatible iPhones, iPads and Macs. Studio Oddscape uses it to deliver terrain models that can be opened directly in AR.

Why do the images look different?

Each image reveals a different reading of the same landscape. A hillshade emphasises form and shadow, a REM reveals local elevation patterns, and a 3D model allows spatial exploration.

What does 1m DTM mean?

A 1m DTM means each grid cell represents approximately one metre on the ground. This gives a useful level of detail for landscape, heritage and terrain interpretation.

Can Studio Oddscape make a terrain study for my site?

Yes. Studio Oddscape can prepare terrain visualisations, LiDAR interpretation, AR terrain models and presentation-ready landscape outputs for suitable sites where appropriate elevation data is available.
