Geographical Information System is a new technology that is fast growing in the world. GIS can be defined as a computerized tools for acquiring,storing,integration,manipulating,analyzing and displaying of spatial (geographical)data. GIS helps in creation of a database which can be easily updated to add current information to suit various applications. GIS make use of an SQL technology which makes it useful in querying information that is available and hence a resourceful tool in structuring.
It hasten and enhance productivity in an organization.
It helps in production of customized map or map tailored to meet specific need at hand.
Integration of many types of data is possible using GIS
Lagos state is a mega city situated in Nigeria, the largest country in African.Lagos state has the highest population as a state situated in Nigeria.It was established 48yrs ago on 27th of May,1967,it has been a place of attraction to many both locally and Internationally for business transactions and tourism. With this it has a set goals to meet its requirement has a fastest growing mega state by providing security,suitable environment for economic growth and financial hub.
Lagos state have various Ministries,Departments and Agencies(MDAs), hence the need for a technology that will enhance excellent collaboration and integration of all the MDAs to ensure their potential is maximized in providing good and services to her citizens.
Hence, the need for technology such as GEOGRAPHICAL INFORMATION SYSTEMS.
Geographical Information is made up of four major technical parts which includes the
- Network (Procedure)
All this work together with reference to people ( GIS Analysts, Specialist, Administrator) and procedural structures within which people work (Professionals).
With development and upgraded of GIS components (software, hardware, data and network) different organizations learn more about GIS and depend on it. GIS becomes useful and interest in GIS grows, to save money and encourage sharing and resource reuse, several projects in the same department may be amalgamated. This has lead to the development of a focused GIS team, creation of common standard and procurement of new GIS capabilities.
This does not mean different departments (MDAs) cannot have different GIS software and their own data standards.
Realization of GIS has been a useful way to structure many of the organization’s assets, processes and workflows. And through its process of natural growth, GIS gradually becomes accepted as an important enterprise-wide information system. At this point GIS standard are accepted across multiple departments and the resources to support and manage the GIS are often centrally funded and managed especially by the Government. With the societal implementation of GIS, hundreds or thousands of users become engaged in GIS and connected by network, hence the name ENTERPRISE GIS.
With the establishment of Lagos State Geographical Information Systems (LAGIS) this shows that Lagos state is developing with the trend of changes that is taken place in the world. Hence, the implementation of easy-to–use menu-driven interface and customized capability which can be distributed over the web, which is in conformity with the world standard (IDEAL)
The following must be evaluated while making decision on Enterprise GIS by the government:
EVALUATING ENTERPRISE GIS REQUIREMENTS
A steering committee that includes stakeholders should be established to guide the needs of assessment process,once a decision has been made to establish an ENTERPRISE GIS.
The following must be evaluated by the assessor or committee to ensure thorough and efficient Enterprise GIS :
- Evaluating Existing GIS Datasets
- Evaluating GIS Resources
- Eliminating Redundancies
- Create GIS-Based Data Service Levels
- Implementing GIS Standards
- Taking Advantage of GIS Software to deliver an enterprise-level database supporting agency needs.
