Über dieses Buch

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.

1. Introduction
Abstract
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 possible to get the desired data.

2. Included software and data
Abstract
If you want to use the software included on the CD-ROM and work with the example data or even use your own materials, it is necessary to have an adequate PC supplied with sufficient main memory (RAM), storage capacity (hard disk) and high resolution graphics. In particular, you need:

3. Scanning of photos
Abstract
A lot of scanners exist on the market with differences in construction, geometric and radiometric resolution, format size and last but not least price. For use in photogrammetry, some basic requirements must be fulfilled: Format A3, transparency unit (for film material), high geometric and radiometric resolution and accuracy.

4. Example 1: A single model
Abstract
To work with the LISA programmes, it is necessary first to define a project or to select one already existing. All projects which we will use during the following tutorials are prepared and have been copied onto your computer in the installation process. Nevertheless, this is a good moment to take a look at this topic.

5. Example 2: Aerial triangulation
Abstract
If LISA FOTO is still running, go to File > Select project and choose the project TUTOR_2.PRJ or, if you have to start LISA FOTO anew, select this project. If necessary, go to File > Edit project and change the path of your working directory (see chapter 4.1).

6. Example 3: Some special cases
Abstract
In this 3rd tutorial, we want to learn some aspects about the handling of special or untypical cases and examples of close-range photogrammetry. What we did until now was to manage data which is typical for (digital) aerial photogrammetry and which of course can be processed with professional software packages — may be, even more comfortably and accurately with them.

7. Programme description
Abstract
In this chapter, a brief description of the LISA FOTO programme is given. Of course, most of it you will already know if you have followed our tutorials. Nevertheless it might be good to have a summary for a quick reference. Thanks to Jörg Jozwiak, University of Duesseldorf, for the translation of this chapter from German to English!
