The Java Virtual Machine seems to support this ambiteous goal. The reality is something else and many difficulties have to be overcome. The development of interactive CAT/CAL programs have to take care of the differences in the platforms and tools. On the other hand the Internet gives access to many other ressources and possibilities which will benefit the CAT/CAL programs. This paper discusses the problems in development and use of the interactive and Internet-based learning program “LDIPInter”. The topic of “LDIPInter" is automatic measurement of images which is a central topic in digital photogrammetry. By means of rolling texts, animations and several tasks with changing data sets the learner becomes interested and active and will understand the process of automatic measurements better than with text books. Articles, manuals and dictionaries, which are accessable by the Internet, can be used in addition. The realisation of good CAT/CAL programs requires many resources, and suggestions are made how an international cooperation could improve the situation. 1. INTRODUCTION The Internet can be used as a learning tool in combination with other aids. Especially in distance education, the Internet will play an important role. By means of the Internet many new opportunities will be created which can support the learning. For example: - search for literature and access to complete texts of articles - use of encyclopaedia, manuals and dictionaries, etc. - communication between students and teacher as well as between students The distribution and use of learning software packages is also possible. The learning by means of these software packages is often called “Computer-assisted learning" (“CAL”) or “Computer assisted teaching” (“CAT”). If the Internet is used as the platform for a CAT/CAL program various advantages can be found (compare figure 1). Thanks to the Java Virtual Maschine (JVM) such CAT/CAL programs are automatically installed on many different platforms consisting of computer, operating system and browser. This platform independence is especially necessary for CAT/CAL programs because many different systems exist in educational environments around the world. Furthermore, the latest version of such a CAT/CAL program can be downloaded from the Internet at any time. There exists a wealth of share- and freeware which could be integrated into new CAT/CAL programs. The development tools (Java compiler, editor, debugger and applet viewer) are also freely available which may start a common development at different locations. The use of a learning program could be monitored (counted) and even charged. With all these advantages in mind, an existing and established CAT/CAL program, “Learning about digital photogrammetry” (“LDIP”), was transferred into an Internet version, called “LDIPInter”. First experiences from the development of this Internet-based CAT/CAL program was presented in (Hohle 1997). In the meantime, new themes were added and experiences gained from its use at different platforms. It is the purpose of this paper to inform about the new achievements and about the user experiences with this type of CAT/CAL programs. In the following chapter the latest version of “LDIPInter” ( 1.14) will briefly be explained. 2. THE CAT/CAL PROGRAM “LDIPInter” The Internet-based CAT/CAL program “LDIPInter” explains the theory behind automatic measurements in images step by step and provides exercises for each step. Currently, it contains two themes: “Automatic measurement” and
