Geographic Information System (GIS) technology is used for collecting, storing, updating, processing, analyzing and displaying of spatial and other related data. A GIS system consists of organized and trained professionals, technical equipment, program support (software) and data. Although the beginnings of GIS development can be traced back to 30 years ago, the real boom was experienced in the last decade when it started to be massively used in remote research, military applications, surveying, geology, forestry, urban planning, local government, environment protection etc. We can certainly speak of a worldwide trend in the collection of spatial data and their transfer into a GIS system. The potential advantages of GIS over the conventional databases (or CAD) are numerous and can be divided into three main groups:- Data visualization,- Linking geographic and attribute (textual) features.
