Geographic information systems (GIS) has become a well-known term all over the world due to its rapid growth all through from the time it had its roots. You might want to have the meaning of the GIS itself but as it has the sounding, it just has the simple meaning of a tool. As questions arise on how and why GIS, there has been its growth and the impact of its development all over the world. In the Easter African Region, there has been the development of GIS and has had a great impact to the economy and its people.
Geospatial information systems has taken a greater role in the planning sector in the Easter African region. It has had its introduction in many planning agencies in east Africa. Urban planners find GIS to be effective tools that can help in information management, processing, dissemination and communication. Initial evidence and the implementation of GIS technology in local governments and planning agencies points to difficulties in getting the systems established and realizing expected benefits. Technological, database and organizational factors make it most challenging to get a GIS to fit and adapt to needs of planning practice. The main sources of evidence to find the mutual adjustment between GIS technology and planning are evaluative studies of existing systems that examine how this GIS affect planning processes and functions.
GIS has had the impact in the health sector in East Africa. A good example is the application of GIS by the Non-Governmental organization known as The World Vision. It has had its accessibility in the location of all the areas to have their helping schemes. Through multivariate spatial statistical modeling of disease processes GIS has improved the health sector in all the East African countries by evaluating potentially disease outbreaks and a more effective allocation of sparse remedial resources towards their containment and prevention.GIS has also assisted users in better understanding the potential harmful effects of environmental pollutants such as toxic waste sites and even in understanding the occurrence of pedestrian and other injuries and crimes.
The agricultural sector has been effected through the introduction of GIS in the Eastern African region. Geospatial technologies are essential for the routing and scheduling of delivery and collection vehicles, for keeping track of the distributed assets of utilities, for improving agricultural production through precision agriculture, and for managing cutting and silviculture in forestry operations. In government, they are essential in support of planning, data-gathering, and assessment.
Geospatial technologies have greatly increased the ability of individuals in East Africa to see what is happening in their own neighborhoods and around the world. Many local communities are employing geospatial technologies to help them understand and manage their own neighborhoods, raise awareness of potential problems, and engage with planning authorities. This have an inclusion of the disaster management strategies and their remedies.
The ability of GIS to overlay existing data with new information and display it in color on a computer screen is used by east African countries primarily to conduct analysis and make decisions related to geology, ecology, land use, demographics, transportation and other domains most of which relate to the human use of physical environment so GIS is a modern tool that is now readily available and usable. This feature has given the ability to involve the East African countries the opportunity to give an overview about their geological aspects.
GIS, through geocoding has made it easy for east Africa to get heights of points such as mountains. GIS has helped many of the East African countries have their street addresses converged in one database and a location of each done in a simple way. Indexes of recognized features such as rivers or lakes also exist, allowing properties associated with such features to be positioned in latitude and longitude; and in East African countries there are recognized systems of formal coordinates such as national grids. One of the great successes of geospatial technology in recent years has been in making it almost trivially easy, cheap, and reliable to convert between these alternative systems of geographic referencing, and to embed these features in countless Web services. The general public in the Region uses these services, often without being aware of their inherent sophistication, in such daily activities as ﬁnding the locations of points of interest such as stores or hotels, acquiring driving directions, or planning travel.
