Digital Terrain Model (DTM): a topographic model of the bare earth surface containing spatial elevation data

Digital Surface Model (DSM): a model of earth's surface including features such as trees, buildings, and vegetation

Digital Elevation Model (DEM): a 3-dimentional representation of elevation values over a topographic surface referenced to a common vertical datum. DEMs are typically used to represent the bare-earth terrain, void of vegetation and manmade features

Point Cloud: a set of data points in some coordinate system. In a 3D coordinate system, these points are usually defined by X, Y, and Z coordinates and often are intended to represent the external surface of an object.

Orthomosaic (Nadir/Oblique): a georeferenced image that can be analyzed in any GIS or remote sensing software.

Contour Lines:  lines joining points of equal value. Typically, these lines join areas of equal elevation above or below sea level

Cross Sections: a surface or shape that is or would be exposed by making a straight cut through something at an angle to view the internal structure

Heat Mapping: a graphical representation of data where the individual values are represented by colours to provide a clear visual summary of the data which is easily understood with high visual impact.

Volumetric Calculations:  volumetric stockpile data is crucial information for a gravel pit or mine operator. Using UAVs for data acquisition increases accessibility to work sites while greatly reducing the potential danger.

Volumetric Comparison: overlaying a volumetric calculation over an existing volumetric calculation in order to compare the differences and gain the cut and fill information.

Triangulated Irregular Networks (TINs): a form of vector-based digital geographic data constructed by triangulating a set of vertices, which are connected with a series of edges to form a network of triangles. TINs form contiguous, nonoverlapping triangular facets and can be used to capture the position of linear features that play an important role in a surface, such as ridgelines or stream courses. TINs have a higher resolution in areas where a surface is highly variable or where more detail is wanted, and a lower resolution in areas that are less variable.

3D Path Profiles: a vertical profile along a user-specified path using loaded elevation datasets. Represents 2D data in a 3D profile view.

Canopy Height Model: a raster representation of the tree canopy. A true CHM is one in which other above-ground features, such as buildings and utility lines, are removed.

Watershed Analysis: enhances our ability to estimate direct, indirect, and cumulative effects of our management activities and guide the general type, location, and sequence of appropriate management activities within a watershed.

Topography: the arrangement of the natural and artificial physical features of an area.

Slope Stability Analysis: an assessment of the safe design of a human-made or natural slope (embankments, road cuts, open-pit mining, excavations, landfills, etc.) and the equilibrium conditions.

Oblique Aerial Imagery: imagery taken at an oblique angle; the camera is directed horizontally or downward.

Flood Simulations: the process of imitating a real phenomenon or process with a set of mathematical formulas

Change Detection: the process of identifying differences in the state of an object or phenomenon by observing it over time.
