Abstract

In many scientific disciplines, fieldwork is used as a way of collecting data. Some of them are geography, geodesy, geology, agriculture, meteorlogy and others. Often young proffesionals, more precisely newly graduated students, although thay have had subjects were mapping was taught, or some similar subject, do not have enough practical experience in performing procedures related to mapping or "working with spatial data". A similar thing can happen with experienced experts in some fields, but who have not dealt with fieldwork. We chose to introduce the term "work with spatial data" because the methodology of the then mapping has changed a lot. Today, there is almost no space on Planet Earth that has not been visited and studied in various ways. Generally, the process involves three phases. The first would be the collection of existing data related to a particular area and issues, with the formation of a preliminary data base of available existing material. The second phase is going out to the field where "in sity" studies of objects of interest would be performed, which are located in a certain area, recording the coordinates of observation points, making documentary photographs, and describing observations (or observation points) and possibly sampling of a different material.Finally in the third phase, based on the existing data and results of fieldwork, a final database would be formed with a textual description and map (maps) of areas and objects of interest will be generated. This papaer presents the main principles and methods of the mentioned activities.
