Geographic Information System
Geographic information systems (GIS) represent integrated solution for the collection, presentation and distribution of space related data as well as information about physical environment. The capability of analysing physical environment data is the most powerful feature inherent in the geographic information systems; it provides the user with an unlimited source of derived information used for a variety of operational tasks as well as strategic management decision-making.
Evaluation of users’ needs through different activities is an essential phase of information system development:
- Collection of information demands
- Definition of demands
- Analysing demands
- Establishment of GIS
The main goal of establishing a GIS model is to achieve an optimal understanding of how processes work and to obtain a basis for establishing a logical and physical model of information system, which is based on our map.
GIS consists of 5 basic elements that are:
- Geo-coded databases
- Organization, processes and methodology
Organizationally GIS is divided into the next subsystems:
- Data grasping (scanning, vectorization, geo location)
- Manipulation with data (maintenance, examination, spatial analysis)
- Presentation (outdrawing, outwriting, digital cartography)
Geographic information system combines features of geographic information systems, technical digital archives and systems for documentation management and hence represents integrated solutions in the field of management of technical and real assets. GIS offers high quality information support in search of data about technical assets, infrastructural systems, real estate’s etc. Main purpose of GIS is to offer support in daily operational tasks as well as in strategic management decision-making. Geographic information system is especially useful in geographic location purposes at:
- Projecting new systems
- Intervening operations
- Commercial representations (location of space, dimension, equipment)
- Making strategic development decisions
- And in many other areas
On the basis of experience we got through working with large business systems, we developed entirely new approach to establishing GIS. We are not limited by specific computer tools and environments; our solution is adapted to users’ computer environment. A uniform database supported by GIS provides adjusted and updated information.
