GIS (Geographic Information System)

What is GIS? Possible some of us have never heard what such by GIS. GIS ( Geographic Information System) or SIG ( Sistem of Information Geografi) is a system which can assist to give the clearer picture about information from a place. End result SIG earn also referred by Smart Maps. This Matter because of end result of SIG it is true represent a map provided with the data required by its maker. Do not like ordinary map is we see the, result from SIG/ GIS own the more complete data and more precise utilize in its exploiting for certain user ( it depends on the requirement).

Exploiting SIG in Indonesia xself blum digunakna widely, though technological exploiting of GIS can assist to know the potency any kind of we which can meet a region or area.

As according to its congeniality of SIG representing a map with the certain data. Data obtained the compiled by laminated above map from a location to be analysed. Later;Then the data united and memebentuk a pattern. just Obtainable data where from. Can from data result of research, satellite perception or from a certain database center ( like resident census, or consumer data).

Data yielded by SIG there having the character of spasial and non spasial. data Spasial is data comprising visual information, like picture of weather perception is above map to be used for the systems analysis of irrigating. While data nonspasial is data in the form of number, like data sum up the resident of per chief of village at certain region. During data obtained by the in form of spasial hence data can be presented directly map. But, if data is in form of nonspasial hence data can be placed at map with the symbol form wanted by the map maker. To yield the correct map utilize, hence existing data will be processed by using software SIG. the Sofware SIG will compile the map by arranging in layers one map with the existing data in one per one.

Pursuant to above description a question emerge what technology SIG same of to GPS? GPS ( Global Positioning System) wide is recognized to know the position a place and have often use of the example by all fisherman to know the area owning fish at most. But technological basically GIS and GPS differ, exactly GPS become one of supporter component in SIG.

Ability GPS which can know the situation of a place precisely can assist the cartography by SIG. On the contrary, very complete map SIG, load of information will be optimal earn more assistive a consumer GPS. Somebody do not can only know the position whereabout he is residing in, but the people can also at one blow know what is going on or owned the its place land stand up.
