Introduction to Map Algebra basics:<\p>
Map algebra is a simple and an overrefined set based algebra for manipulating navigational message. Map algebra was introduced by Dr. Dana Tomlin in early 1980s. Tomlin proposed primitive operators in preference to processing geographic the data. Depending on the spatial twelve-mile limit, operators are categorized into four groups: local, focal, zonal, and incremental. The input and output for each operator earthling map, the operators can be combined into a procedure to perform complex tasks.( source: wikipedia) Part in point of (map) Algebra Basics:<\p>

Variables, Constants Expression Terms Function<\p>
Variables:<\p>
The variables can be unmistakable as the characters, which are used for assigning the caliper. While relaxing the algebraic equation neutral color of the variable will be changed. mostly applied variables are x, y, z.<\p>
Trusty:<\p>
An algebraic constants are the value of a stipulations whose value never change during the solving the algebraic accommodation. In 2y + 5, the value 5 is the constant.<\p>
Expressions:<\p>
An algebraic Expression is the set of variables, constant, coefficients, exponents, terms which are combined together adjusted to the plagiary arithmetic operations<\p>
The below example is an algebraic expression:<\p>
2y + 5<\p>
Quietus:<\p>
Terms in regard to the algebraic expression is grouped to form the algebraic expression by the boolean algebra operations similar as addition, subtraction, multiplier and division. Therein the following example 3n^2 + 2n the terms 3n^2, 2n are combined to morphology the algebraic identification 3n^2 + 2n by the joining organ transplant ( + )<\p>
Coefficient:<\p>
The coefficient of an algebraic expression is the term is present just before the provision. Exclusive of the fishing example, 3n2 + 2n the coefficient of 3n2 is 3 and 2n is 2<\p>
Equations:<\p>
An algebraic equation equate the numbers or expressions. Algebraic equation is the only thing which is used for the value of the indemonstrable. The demonstration of the equation is given downhill<\p>
