Raster, TIN, terrain, and LAS datasets are all types of a functional surface.
You can also convert between these surface models. You can build triangulated surfaces by creating a TIN, terrain dataset, or LAS dataset. There are several interpolation methods to create raster surfaces, such as Inverse Distance Weighted, Spline, Kriging, and Natural Neighbor. The two main methods of creating surface models are interpolation and triangulation.
These surface models can be created from a variety of data sources. ArcGIS can create and store four types of surface models: raster, triangulated irregular network (TIN), terrain datasets, and LAS datasets. Imaginary examples of 3D surfaces are often the types found in video games or computer simulation environments.Ī 3D surface is usually derived, or calculated, using specially designed algorithms that sample point, line, or polygon data and convert it into a digital 3D surface. Those contaminants could be mapped as a 3D surface too. An example of a derived surface is the contaminant levels of a particular bacteria in each well. These are all examples of real features, but surfaces could be derived or imaginary. Some simple examples of 3D surfaces are a landscape, an urban corridor, gas deposits under the earth, and a network of well depths to determine water table depth. A 3D surface model is a digital representation of features, either real or hypothetical, in three-dimensional space.
