Georeferencing of vector and raster layers in GIS – meaning, description and approach

Georeferencing will align different types of geographic information to a known geographic coordinate system. This allow to view the respective information together with another already georeferenced layers of information. The process include shifting, scaling, rotating, rectifying and etc. the data. In other words it provide geographical coordinate systems for all layers.

Step by step approach
  1. Coordinate system: Define the coordinate system of already referenced layers;
  2. Align the input information to the existing layers with already available geographic coordinate system;
  3. Upload the information in the database together with other layers.

Geographic information systems (GIS)

Geographic information systems (GIS) – abbreviation, meaning, description and benefits

A geographic information system (GIS) is information system including, software, hardware, data, databases, users and procedures necessary allowing users to collect, manage and also analyze geographic information. The biggest advantage of this information system is the opportunity to combine all types of information with geographic locations. As a result, it is possible to compute a lot of statistical procedures. This allow better understanding of geographic patterns and the significance level that they occur.

There are two key components of GIS – geographic data and users. Most of all, the users should be familiar with the software and procedures. This is important in order to upload information in the system and to perform its validation, georeferencing and describing.
