Technological advancements in recent years, along with utilization of information process and presentation systems, have led different sciences to make great process through effective use of these factors.
The paper presented here is an example of utilization of laser technology and computer systems in geographic information research and cartographic maps. The experimental method studied in this paper is the combination of regular laser-based photogrammetric system of measuring points’ elevation with GPS. The reason for using this system is that there already exist large-scale maps of lands in many European countries (in some of these countries even maps of 1: 500 scale are available).
Therefore, there is no need for new surveying in the real sense in these areas. The only necessity is updating maps.
This issue is of great importance in Netherlands, considering its special topographic conditions which are always changing. However, utilization of ordinary surveying methods is time-consuming and costly, while application of Laser Sweep Method (studied in this paper), when combined with GPS, can lead to provision of planimetric and elevation information of points in the studied area.
This paper examines the works in this regard, with the hope that it will be useful for those interested in related fields.
