Normalization
The database to be GIS enabled must be “normalized.' Normalization is a database design that allows for efficient access, storage, and maintenance of data in an object relational database.
Normalization and Proportional Symbols
This document looks at one of the common fallacies committed by beginning cartographers -- creation of maps where the colors of areas are driven by statistics that represent counts.
normalizationA conceptual database design task that involves applying data dependency to a data model to avoid data inconsistencies by prohibiting redundancy.
[edit] Normalization
Main article: Database normalization
Normalization was first proposed by Codd as an integral part of the relational model.
Normalization can express an attribute as a percentage of the total. For example, a map could be made to show each stand's contribution of fiber in comparison to the total amount of fiber on the forest.
Normalization - In relational database design, the process of organizing data to minimize duplication and ensure integrity. Normalization usually involves dividing a database into two or more tables and defining relationships between the tables.

denormalization The process of restructuring a normalized data model to accommodate operational constraints or system limitations. densify A process of adding vertices to an arc at specified distances, without altering the arc's shape.
The divisor is a normalization factor to take into account the unequal weights in the weighted average.

One or more relational tables with appropriate primary and secondary keys (this assumes the desired level of normalization has been obtained);
The corresponding spatial entity for the "regular" entity.
Among these operations are addition, subtraction, multiplication, division, exponentiation, maximization, minimization, normalization and other scalar mathematical and statistical operators.

If an atmospheric model is omitted, the parameters developed to extract information from the image are not transferable and the entire procedure must be repeated for other images. Several methods for the normalization or radiometric calibration of ...
