Many of these items are used in research; nevertheless, students have access to 
every thing.In addition, our students have access to the Intergraph system of the Institute 
of Cartography. 
Of key importance for instruction in digital photogrammetry and remote sensing is our 
Digital Station DIPS (II). For a more detailed description see Grucn, 1989 and Gruen, 
Bever 1990. DIPS II (Digital Photogrammetric Station II), consists of a number of Sun. 
Workstations (Sun-3, Sun-4, SPARCstations) linked to each other via Ethernet with some 
external off-the-shelf components for digital image acquisition and output. All 
workstations can act individually or together as programming and processing platforms. 
Most software is written in C with a few minor portions in FORTRAN 77. Of particular 
value is DEDIP (Development Environment for Digital Photogrammetry) which is written 
in C, uses the SunView window environment, provides for data structures and user 
interface, and acommodates most newly written programs. DIPS II serves as an 
indispensable tool and platform for all research and development projects of our group in 
digital photogrammetry, remote sensing, machine and robot vision. At the same time it is 
an"excellent device for students to familiarise themselves with the basics and procedures of 
these disciplines. 
DIPS n currently consists of: 
• 7 SPARCstation 1GX, each w'ith 12 MB memory and GX graphics accelerator 
• 1 Sun-4/280 and 1 SPARCserver 490 fileserver with a total of 5 Gbyte of disk space 
• 1 Sun-3/110 primarily used as S9-AP support and with 8 MB of memory 
• ’ Sun-3/E workstation with 8 MB of memory, mainly used to support the 
DATACUBE system
