GIS or Geographical Information System is a type of system that is designed to store, capture, analyze, manipulate, present and manage all the types of geographical or spatial data. The GIS is sometimes referred to the academic discipline, which studies geographic information system when it is used for the geographical information science or GIScience. Moreover, sometimes it is also referred to as large domain within the broader academic discipline of the Geoinformatics.  

The GIS applications are the tools used that allow the users in creating the interactive queries, edit data in maps, analyze spatial information and present results of the overall operations. This is best used and utilized by the Research Centers.

The GIS will enable you to envision the geographical aspects of the whole data or information. It allows you to analyze or query a particular database and be able to receive the maps through the form a map. It has several uses that include sales analysis, weather forecasting, land use planning, population forecasting ad more.

In the GIS Centers, the geographical information is described implicitly in terms of postal code, street address or forest stand identifier and/or described explicitly through geographical coordinates.  

The GIS has the ability to translate the implicit geographical data, such as street address, into explicit map location. The developers of the GIS usually obtain the map data form the companies or public sources that specialize in organizing and collecting the geographic data.

The geographical data or information can be stored in the format of raster graphics or vector graphics:

·         Vector graphics format

Through the vector format, the two-dimensional data can be stored in terms of the x and y coordinates. A concrete example is the river, which can be described as the series of x and y coordinates. Town boundaries, which are considered as non-linear features, can be stored as the closed loop of coordinates. This format is in describing those well-delineated features.

·         Raster graphics format

The faster data format is expressing the data as continuously changing set of the grid cells. This is usually used for portraying subtle changes that includes soil type patterns over a particular area.

Almost all of the geographical information systems are using both the raster and vector data. The GIS is widely used on Research Center, which had proven to be useful and beneficial.

The GIS do the following:

·         Rescaling or manipulating the geographical data for various purposes

·         Accepting geographical input through the form of digitized and scanned-in map images

·         Including the database manager that is usually “relational database management system”

·         Providing answers visually and is usually as graphs and maps

·         Including analysis programs in order to retrieve the answers into simple questions like distance between two points on a particular map or more complicated questions requiring further analysis such as to determine the traffic pattern at given intersection

The GIS is easy and convenient to install in any of your devices for fast transactions and analysis of data or significant information. However, it pays you to have enough knowledge and skill on how to use it effectively and productively.

heeeeeelp.

Today we need your immediate support on a Tumblr campaign to scale a UNICEF tool that fights for the environment. Last year we launched UNICEF GIS, a mobile and web system that allows youths to report environmental hazards and risks to duty bearers and then see through community changes and fixes. In the last six months we trained 111 young people from the favelas of Rio De Janeiro, Brazil and the government took direct action on their reports. Now we need your support  to scale this tool to hundreds of communities, thousands of youth and to every risk and hazard that threatens children's lives. We are not asking for donations, but only your voice in our Knight Foundation News Challenge Campaign.                                                                                   

Please take the time to watch a 5 minute video about our initiative, read our Knight Foundation Entry and then visit the UNICEF GIS Tumblr to offer your ideas, likes, and reblogs. We want all your support to spread this idea and realize a safer, healthier future.

Got this submission from the UNICEF. They need your help in reporting the dangers that are faced by the youth in your own neighborhood.

Please do watch the video they have linked above. Your time and effort in knowing about their campaign and sharing it, would mean so much to helping out kids in dangerous and unhealthy environments.
