Modeling:
Applying structured rules and procedures to one or more spatial database overlays to conduct spatial and/or network analysis to derive new information to aid in problem solving and planning.

Modeling - (1) The process of creating a model. (2) A stage in scientific investigation involving the development of abstraction, theories and mathematical formulae to simulate real world processes or phenomena.

moment The moment is the time when all the tasks associated with a transaction have completed. A feature's creation, deletion or update date is set to the transaction's moment.

[modeling] A set of rules and procedures for representing a phenomenon or predicting an outcome.
[data models] A data representation of reality, such as the vector data model.

A modeling language to define the schema of each database hosted in the DBMS, according to the DBMS data model.

Data modeling
It is difficult to relate wetlands maps to rainfall amounts recorded at different points such as airports, television stations, and high schools.

Data modeling
It is impossible to collect data over every square meter of the Earth's surface. Therefore, samples must be taken at discrete locations.

solid modeling
The process of rendering a 3D surface from vector type data.

spatial modeling Analytical procedures applied with GIS. There are three categories of spatial modeling functions that can be applied to geographic data within a GIS: geometric models, such as calculating the distance between features, ...

Predictive Modeling
Site location modeling is a useful GIS product for archaeologists who wish to locate and protect unknown cultural resources.

Cartographic Modeling
The previous sections described many of the processes of a GIS.

The process of modeling, examining, and interpreting model results. Spatial analysis is useful for evaluating suitability and capability, for estimating and predicting, and for interpreting and understanding.

Decision Rules - In many predictive modeling projects, statistical formulas that determine points along a continuous logistic transformation scale that permit decisions to be made about the presence or absence of archaeological resources.

The research on object-orientation approaches has four main topics: data modeling, programming languages, database management systems and user interfaces (Maguire, 1994).

In addition to modeling the satellite-clock errors and in an effort to remove them, an additional satellite should be observed during operation to solve for an extra clock offset parameter along with the required coordinate parameters.

The relationship between NAD27 and NAD83 includes the change in the reference ellipsoid as well as modeling of the NAD27 distortions which exhibit regional trends in certain areas and regions where the distortions appear random.
