The vector from an observer (origin) to a point of interest in the sky is projected perpendicularly onto the equatorial plane; the angle between the projected vector and the reference vector on the reference plane (usually the direction to the sun as it crosses the equatorial plane at vernal equinox) is called the azimuth of the point of interest.

type: Class
subclass of: InformationContentEntity
comment: A collection of facts from which conclusions may be drawn (Source - WordNet #1) The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. (Source - Wikipedia)

Data analysis
type: Class
subclass of: Mathematical analysis
comment: Analysis of data is a process of inspecting, cleaning, transforming, and modeling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision making (Source - Wikipedia).

Data mining
type: Class
subclass of: Data analysis
comment: Data mining is a particular data analysis technique that focuses on modeling and knowledge discovery for predictive rather than purely descriptive purposes. Specifically, it is the process of discovering new patterns from large data sets involving methods from statistics and artificial intelligence but also database management. In contrast to for example machine learning, the emphasis lies on the discovery of previously unknown patterns as opposed to generalizing known patterns to new data (Source - Wikipedia).

Descriptive statistics
type: Class
subclass of: Statistics
comment: Descriptive statistics summarize the population data by describing what was observed in the sample numerically or graphically. Numerical descriptors include mean and standard deviation for continuous data types (like heights or weights), while frequency and percentage are more useful in terms of describing categorical data (Source - Wikipedia.org)

Error analysis
type: Class
subclass of: Statistics
comment: Error analysis is the study of kind and quantity of error that occurs, particularly in the fields of applied mathematics. In numerical simulation or modeling of real systems, error analysis is concerned with the changes in the output of the model as the parameters to the model vary about a mean. (Source wikipedia.org)

fast Fourier transform
type: Class
subclass of: Fourier transform
comment: FFT

Forecast
type: Class
subclass of: Prediction
comment: Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively to less formal judgemental methods. (Source - Wikipedia.org)

HorizontalCoordinateSystem
type: Class
subclass of: CoordinateSystem
comment: The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane. This coordinate system divides the sky into the upper hemisphere where objects are visible, and the lower hemisphere where objects cannot be seen since the earth is in the way. The pole of the upper hemisphere is called the zenith. The pole of the lower hemisphere is called the nadir. The horizontal coordinates are: * Altitude (Alt), sometimes referred to as elevation, is the angle between the object and the observer's local horizon. It is expressed as an angle between 0 degrees to 90 degrees. * Azimuth (Az), that is the angle of the object around the horizon, usually measured from the north increasing towards the east. * Zenith distance, the distance from directly overhead (i.e. the zenith) is sometimes used instead of altitude in some calculations using these coordinates. The zenith distance is the complement of altitude (i.e. 90°-altitude).

Inferential statistics
type: Class
subclass of: Statistics
comment: Inferential statistics uses patterns in the sample data to draw inferences about the population represented, accounting for randomness. These inferences may take the form of: answering yes/no questions about the data (hypothesis testing), estimating numerical characteristics of the data (estimation), describing associations within the data (correlation) and modeling relationships within the data (for example, using regression analysis). Inference can extend to forecasting, prediction and estimation of unobserved values either in or associated with the population being studied; it can include extrapolation and interpolation of time series or spatial data, and can also include data mining (Source Wikipedia).

Landform
type: Class
subclass of: PlanetPart
subclass of: GeographicFeature
comment: A landform comprises a geomorphological unit, and is largely defined by its surface form and location in the landscape, as part of the terrain, and as such, is typically an element of topography. Landforms are categorised by features such as elevation, slope, orientation, stratification, rock exposure, and soil type. They include berms, mounds, hills, cliffs, valleys, rivers and numerous other elements. Oceans and continents are the highest-order landforms. (Source - Wikipedia.org)

TopographicFeature
type: Class
subclass of: PhysicalObject
comment: Topography (from Greek τόπος topos, "place", and γράφω graphō, "write") is the study of Earth's surface shape and features or those of planets, moons, and asteroids. It is also the description of such surface shapes and features In a broader sense, topography is concerned with local detail in general, including not only relief but also vegetative and human-made features, and even local history and culture. This meaning is less common in America, where topographic maps with elevation contours have made "topography" synonymous with relief. The older sense of topography as the study of place still has currency in Europe and that is what is meant here (Source - Wikipedia.org)
