摘要:

AbstractThe use of present-day cadastral maps for computer-aided information systems requires, over and above the pure digitisation of the map information itself, the thorough geometrical improvement of locational data. For this, the inhomogeneities between the individual sheets themselves, or between the graphically obtained coordinates on the one hand and the more precise coordinates obtained through measurement and calculation on the other need to be removed as thoroughly as possible. Following this, the geometrical conditions contained in the graphical structures need to be restored in the digital data file. These measures result in specific demands being made of the map digitisation procedure and of the storage in a corresponding graphics system. The following article describes the conceptional foundations of a program system called DAVID (which in German stands for:Digitalisierung,Aufbereitung undVerbesserunginhomogenerDaten) and which was developed for the digitisation, preparation and improvement of inhomogeneous data from cadastral maps.

摘要:

AbstractThe Statutes of the FIG contain a comprehensive definition of what surveyors do; the broad scope of surveying follows from the names and subject areas of the FIG Commissions. The present paper will be mainly devoted to land surveying in a broad sense, and leave out of consideration the types of surveying in which land surveying plays a very modest part, or none at all.

摘要:

AbstractThis paper presents a mathematical model of threedimensional adjustment of local geodetic nets and investigates the possibility of its application in engineering geodesy. Illustration of the possible application of threedimensional adjustment is demonstrated in the presentation of results of its application on the deformity model of the Brestovac Dam.

摘要:

AbstractIn how many survey courses does each student dismantle and re-build an old theodolite; or is an umbrella used as a portable planetarium; or are theodolites used to teach photogrammetric aerotriangulation; or is EDM used to illustrate satellite doppler principles?
