The phrase "terrain surface" is correct and usable in written English.
It is commonly used in descriptive writing or technical writing to refer to the physical characteristics of a particular area of land. Example: The hikers were struggling to navigate the rugged terrain surface as they made their way up the steep mountain path.
The routes shown in the 3D model terrain surface.
However, these models change as the terrain surface varies.
A visual odometry sensor looking down the terrain surface is employed to measure the motion of the UGV, by tracking features selected from the terrain surface.
A digraph is utilised to describe the terrain surface which has been partitioned into uniform grids.
Europe's Mercury Planetary Orbiter will focus on the surface of the planet, analyzing terrain, surface composition, and the layers of the planet beneath the crust.
The terrain surface is taken into account, using 2-D adaptive meshes of triangles which are constructed using a refinement/derefinement procedure in accordance with the variations of terrain surface and albedo.
This interpolated surface helps in proper representation of the terrain and was checked under different terrain surfaces.
In this paper, we propose a new method of simplifying terrain surfaces, designed specifically to maximize a new measure of quality based on preserving inter-point visibility relationships.
For simulations using smooth terrain surfaces, such as racetracks or highways, data can be down-sampled through a mean interpolation method to smooth the artefacts of inertial errors.
Natural shear forces due to gravity along inclined terrain surfaces are controlled by the inclination of the terrain, material composition and its mechanical properties, stratification and hydraulic stress states.
The VTI code replaces the tire component of the simulated vehicle, in the Driver and Motion Simulator (DMS), allowing it to report back realistic values while driving on various types of terrain surfaces such as mud, snow, ice, and pavement.
