Noise in Ca to, aphic Communication
@The cartogra!hic !rocess is disturbed at certain !ointsin an un!lanned way$ This unwanted disturbance iswhat is nown as Noise .
@ It is anything in the signal or channel that disturbs orinterferes with the transmission% such as distractinggra!hic !atterns on the ma! or !oor lighting% whichblurs ma! isibility$
@It may be identified in language as bad oice% static inradio or in T, as distortions on the screen$

C&NCLUS &N >.@ The cartogra!hic communication !rocess can only besuccessfully accom!lished if the sender (cartogra!her)!roduces a signal (the ma!) which is understood by therecei er (the ma! user)
@uccessful cartogra!hic communication is more thandeci!hering and understanding indi idual symbols$ It is alsothe full understanding of
geogra!hical or s!atial conce!ts% distributions and relationshi!s
@C5isting nowledge with the ma! user and the study of thema!% may lead to inter!retations and to information oftenbeyond the content of the ma!$

C&NCLUS &N >2@ =ne of the re'uirements for achie ing such understanding of
relationshi!s and s!atial distributions is the !ro!er design ofsymbols or gra!hics by the cartogra!her to !ortray information
@ +emember that symbol design is not >ust the ability to designand assign different symbols for each sub>ect or ob>ect to
a!!ear in the ma! it is more im!ortantly% the intellectual process of the design of an harmonious set of symbols that properly portray the type, character and location of the singleor grouped elements in the map
@ At the same time% the ma! !ortrays the total sub>ect matter(grou!ed elements) of the ma! as a well as balanced entitybetween the cartogra!her and the ma! user$

Although the arious com!onents of the communicationsystem may be 'uite different from any another elementof the system% the fundamental characteristics of allcommunication systems are similar$
@In order to em!loy any system to the best ad antage% theattributes of each com!onent must be clearly understood(A onto !rs "ospel music#)

+C,ICF G&C TI=B Fith reference to illustrati e diagrams discuss the definition of
the ma! as a communication system Account for B=I C in .artogra!hic .ommunication and e5!lain
briefly how can it can arise or be minimi:ed?
Distinguish between the cartogra!herHs reality and the ma!users reality$ Fhat accounts for any such discre!ancies?
