Photogrammetry is a science based technology with more than a century of history and development. During this time, the techniques used to get information about objects represented in photos have changed dramatically from pure optic mechanical equipment to a fully digital workflow in our days. Parallel to this, the handling became easier, and so its possible also for non-photogrammetrists to use these methods today. This book is especially written for potential users which have no photogram metric education but would like to use the powerful capabilities from time to time or in smaller projects: Geographers, Geologists, Cartographers, Forest Engineers who would like to come into the fascinating field of photogrammetry via "learning by doing". For this reason, this book is not a textbook - for more and deeper the ory, there exists a lot ofliterature, and it is suggested to use some ofthis. A special recommendation should be given to the newest book from KONECNY (2002) for basic theory and the mathematical backgrounds or to the book from SCHENK (1999) for the particular situation in digital photogrammetry. For a quick reference especially to algorithms and technical terms see also the Photogrammetric Guide from ALBERTZ & KREILING (1989). This book includes a CD-ROM which contains all you need from software and data to learn about the various methods from the beginning (scanning of the pho tos) to final products like ortho images or mosaics.

Photogrammetry is the use of photography for surveying primarily and is used for the production of maps from aerial photographs. Along with remote sensing, it represents the primary means of generating data for Geographic Information Systems (GIS). As technology develops, it is becoming easier to gain access to it. The cost of digital photogrammetr

1.1 Basic idea and main task of photogrammetry If you want to measure the size of an object, let’s say the length, width and height of a house, then normally you will carry this out directly at the object. Now imagine that the house didn’t exist anymore – it was destroyed, but some historic photos exist. Then, if you can determine the scale of the photos, it must be pos- ble to get the desired data. Of course you can use photos to get information about objects. This kind of - formation is different: So, for example, you may receive qualitative data (the house seems to be old, the walls are coloured light yellow) from photo interpre- tion, or quantitative data like mentioned before (the house has a base size of 8 by 6 meters) from photo measurement, or information in addition to your background knowledge (the house has elements of the “art nouveau” style, so may be c- th structed at the beginning of the 20 century), and so on.

The first attempt to investigate this pervasive biological phenomenon from a variety of disciplines, from physics to mathematics to biology.

This text is designed to give students a strong grounding in the mathematical basis of photogrammetry while introducing them to related fields, such as remote sensing and digital image processing. Suitable for undergraduate photogrammetry courses typically aimed at junior and senior students, and for graduate-level courses at the Master's level. Excellent reference for those working in related fields.
