[Termes IGN] voxelRésumé : (Auteur) Visualisation of the complex spatial and temporal relationships characteristic of environmental analysis remains a serious problem in GIS because difficulties are experienced in mapping true 3D data, in handling time, and with the display of multiple parameters to explore correlations. This paper describes how this situation can be improved by combining a GIS with a specialised visualisation system capable of providing interactive 3D displays for manipulating volume (voxel) models. Hence, time can be treated as independent of spatial data rather than just another attribute, which enables the development of spatiotemporal isosurfaces and the extension of data exploration techniques into 4D via animation. This approach also allows us to handle and display multiple parameters more effectively meaning that information can be communicated in a more powerful manner. These advantages are illustrated by analysis of climatological data-sets and the monitoring of air pollution parameters. The techniques described are likely to become much more accessible in future with the advent of dynamic and collaborative visualisation on the Internet.

However, in more than half the cases complete or correct plans are not available. The geometry of a building has therefore to be determined by surveying. The classical techniques in geodesy consist in observing discrete points where the object is represented by specially selected points.
An effective surveying method is presented here of scanning the object. The measuring sensor of the scanningsystem is an automatic tacheometer which consists of a motorized theodolite with an integrated reflectorless measuring laser ranging device. In order to realize the scanning method the tacheometer has to be controlled by a PC. In 1992, at the outset of these considerations, no instrument with the characteristics necessary for automatic surveying was available. Therefore, a prototype had to be constructed.
As horizontal and vertical intersections of the objects are generally required, steeringalgorithms have been developed to measure these profiles directly but completely independent of the position of the instrument. Adapted to the local object structure, the position of the profileplane and the space between the points to be scanned are determined before the system is started. The coordinates of each objectpoint are precalculated from the positions of the previously scanned points of the profileline. The horizontal direction and vertical angle of the tacheometer are set by the servo drives and the slope distance is measured. - The result of the measuring process are three-dimensional coordinates of all scanned points, which are situated in the profileplane.
The obvious problem is, that corners and edges can not be measured directly. They have to be derived by intersecting the straight lines belonging to the adjacent parts of the profileline. - To determine the surface-structure of an object an optional number of parallel profilelines is scanned. As a result, the 3D-geometry of an arbitrary surface is described by a dense grid of points. Practical examples for scanning objects are given.
Generally speaking, the accuracy of the measuring results depends on several factors. Systematic deviations in connection with the reflectorless distance measuring are of importance here. There are two different causes: the range finder needs two lenses, one to emit and one to receive the signal, and the target point of the distance measuring beam is not defined exactly. So special instrumental errors must be taken into consideration when measuring reflectorlessly with a tacheometer. The deviations caused by the parallactic angle, the eccentricity of the reference axis for the distance measuring and the axis error of the same reference axis are treated in detail.Numéro de notice : 28035 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=63382 Réservation
