Modern measurement technologies such as laser scanning provides infor-mation about the reality that surrounds us in the form of point clouds. However, the information about the geometry of the objects stored in this form is often impractical from the point of view of the recipient. Therefore, it is necessary converting point clouds to vector models supported by CAD software. This paper presents the applicability and use some 3D modeling tools available in the software Leica Cyclone, as well as the accuracy of the fitting obtained geometry in the point clouds. ...
The aim of this work is to show the possibilities of using laser scanner in ecosystems preservation on the stage of making spatial planning decisions. The laser technique of automatic measurement enabled us to get measurable and fully objective spot elevation model very quickly. Received scan was converted into spatial model by adding texture and later on merging increments of development in their natural surroundings. The visualization created can be very helpful when choosing the best option of land development; moreover, it can help protecting the land from investments leaving it in its original shape. For the purpose of the research supporting ecosystems preservation, two chosen objects, located in Sobótka (Sobótka commune) and Maniów Mały (Mietków commune), were diagnosed. Field investigations were conducted in the years 2011-2012. It was concluded that the afforestation of one of the investigated area according to the existing regional policy would block the view on the Zbiornik Mietkowski dam coping. ...
Digital photogrammetry is one of the intensively developing areas of technical sciences. Increasing participation in the surveying works have digital devices and solutions giving new possibilities in creation of the appropriate map elements and models as well. A particular role to play has the laser scanning technology allowing to present surveyed space or area in the 3D form. Digital Terrain Models for agricultural areas obtained on its basis may be presented in different ways using professional software.Due to the fact, that in recent years almost the entire Poland was covered with laser scanning, collecting information about the Earth's surface in the form of a cloud of points with high accuracy is a relatively fast process and the results of their elaboration are widely used in many fields.The paper presents the methods of Digital Terrain Models visualization of agriculture areas for three different objects created on the basis of data derived from airborne laser scanning. The study included agricultural locations - two of them (Strzelce Wielkie and Kamionka Wielka) located in the Malopolskie Voivodship, the third - Mątowy Wielkie in Pomorskie Voivodship, in Żuławy. DTM visualizations were prepared in Macrostation, Terrasolid and Surfer 10 software. For the Mątowy Wielkie object ...
