Das Terrestrische Laserscanning (TLS) hat sich in den letzten fünf Jahren zu einem Messverfahren entwickelt, das viele Vorteile gegenüber den herkömmlichen Methoden (Photogrammetrie, Tachymetrie) bietet. Die Datenerfassung (Scannen) ist einfach und leicht zu erlernen. Diese Erfahrung verleitet dazu, eine Messaufgabe, bei der TLS als Erfassungsmethode genutzt wird, insgesamt als einfach einzuschätzen. Die Erfahrungen jedoch zeigen, dass eine sorgfältige Planung des Gesamtprozesses, bestehend aus den Schritten Erfassen, Aufbereiten und Visualisieren, eine unabdingbare Voraussetzung für einen zufriedenstellenden Projektabschluss ist. Der vorliegende Band vermittelt notwendiges Wissen in Form von Grundlagen, Ergebnissen aus realen Untersuchungen und Erfahrungen aus konkreten Anwendungen.

The series is aimed specifically at publishing peer reviewed reviews and contributions presented at workshops and conferences. Each volume is associated with a particular conference, symposium or workshop. These events cover various topics within pure and applied mathematics and provide up-to-date coverage of new developments, methods and applications.

In the 19 years which passed since the first edition was published, several important developments have taken place in the theory of surfaces. The most sensational one concerns the differentiable structure of surfaces. Twenty years ago very little was known about differentiable structures on 4-manifolds, but in the meantime Donaldson on the one hand and Seiberg and Witten on the other hand, have found, inspired by gauge theory, totally new invariants. Strikingly, together with the theory explained in this book these invariants yield a wealth of new results about the differentiable structure of algebraic surfaces. Other developments include the systematic use of nef-divisors (in ac­ cordance with the progress made in the classification of higher dimensional algebraic varieties), a better understanding of Kahler structures on surfaces, and Reider's new approach to adjoint mappings. All these developments have been incorporated in the present edition, though the Donaldson and Seiberg-Witten theory only by way of examples. Of course we use the opportunity to correct some minor mistakes, which we ether have discovered ourselves or which were communicated to us by careful readers to whom we are much obliged.
