GIS for you:
MPGIS offers this GISforYou section specially for you; for helping you all who wish to take to GIS, who want to learn GIS, who want to apply GIS efficiently and at the same time, also those who are already power users of GIS and need to upgrade their working. The MPGIS site caters to all needs of using GIS, GIS mapping and GIS applications.
MPGIS site is unique of its kind that has Information and Education together. What has been served here is: Details about GIS, GIS application areas, and more particularly Watershed GIS. It also has handy GIS tools and GIS utilities for GIS users like Lat-Long to UTM converter, UTM coordinate finder, and much more. This site also would take you to several places on Web related with GIS and GIS maps... so you won't have to search anymore but, instead, this site would give you the leads.
GIS and Maps:

Maps have come in as the best form of presentation of information. Maps have a language that even a layman can understand. Obviously the educated class and the experts may go far beyond simple perception of data and may actually derive many useful conclusions easily which can bring lot of change in their day to day working mainly related to planning and monitoring activities. |
'No body has time to read thick volumes of Tables and go through voluminous Databases'. Maps are far more a useful medium than narrative form of information. Maps present a bird's eye view, that is looking entire details of entire area just on one scene. And when maps are put on computers, that is in digital form, these become much more useful. The GIS techniques are used to computerise the maps. Rather, computerisation of maps alongwith data generates a GIS. .
What is GIS:
GIS is, in simple terms, a system of geographic information or information about earthly objects, for a defined area, depicted on the Maps using special softwares. |

All objects on earth for that matter such as trees, buildings, farms, wells, pond, roads - virtually everything that we see, have their specified location. These may be identified with Lat-Longs - or Latitudes and Longitudes. The maps can easily show each object and area, with the help of these location values in miniature form as per a given scale. |
The GIS starts building with the maps getting recorded [or digitized as the term is] on the computer. The important component of GIS is - Data. The data related to the objects on the digitised maps is imported from database systems into the GIS easily and is attached to the corresponding objects or areas, thus making the maps far more information-ful and meaningful.

The GIS maps may further have layers - multiple layers of maps. From the same place and area, of almost the same territory, but different information be stored on different Maps or layers. GIS has capability to play with these layers: to put one over the other, show layers by selection, as required, etc. |

GIS has other interesting capabilities also, like enlarging or reducing the maps on screen - this is known to be Zoom-in and Zoom-out feature of GIS. You may imagine how a big Map of a large area would appear on small screen of computer. Naturally the things would look pretty small and congested. To take a close look, you would like to enlarge it. This is called as Zooming-in. To a map, if you apply Zoom-in, it will start showing the map enlarged stage by stage. Go to a level where you are able to see the map elements clearly. To ellaborate, imagine of a birds-eye-view at the start from a very high altitude when you would be able to view larger area but all objects would look smaller. The moment you start coming to lower heights, the things become clearer and clearer. But in this kind of scene, now you would be able to view only smaller piece of land on earth. So while talking about the Zoomed-in view of map on computer screen, only a part of the Map would be visible before you on the screen.
Next, you would like to browse the adjoining areas. Move right and left, up and down, on the screen - is what you would want to do. This is called as Pan the map and that’s another feature on GIS. To have a look at the data, you would like to view several records together in browse mode or would like to see one set of record at a time! There are commands available to do either. Thus, data about each and every object is readily available in the same GIS map window.
You have understood, most of basic features of GIS now in-fact.
