3.2 Education 
3.2.1 Photogrammetry and remote sensing courses 
In the photogrammetry and remote sensing discipline following 
undergraduate courses are currently given and similar courses 
have been given during the period 2000-2004: 
3.2.2 Photogrammetry and image processing, levelA-basic. 
(in Swedish) 
The course is an introduction to photogrammetry whit focus on 
photogrammetric mapping from aerial images. Throughout the 
course a project work is realised, including orientation of a 
stereo pair and stereo plotting in both an analytical instrument 
and a digital photogrammetric workstation. Basics in image 
processing processes, related to digital photogrammetry, are 
also covered. 
3.2.3 Photogrammetry analytical/digital, levelB- 
intermediate. (in English if requested) 
The course includes analytical fundamentals in photogrammetry 
and standard processes in modern digital photogrammetry; c.g. 
aerial triangulation, generation of elevation models and 
production of ortho photos. 
3.2.4 Remote sensing level C-advance. (in English, if 
requested) 
Different types of satellites, sensors, etc., are treated. However, 
the main emphasis is put on image interpretation and analysis. 
The course also consists of a project work where a satellite 
image is classified with respect to land use. 
3.2.5 Industrial and special measurements level C (advance). 
(in English, if requested) 
Terrestrial photogrammetry is treated in the course with the 
purpose of detecting e.g. displacements caused by, for instance, 
stress. Also detection of 3D medium- to high-speed movements 
by photogrammetric methods are treated. 
3.2.6 Thesis work 
Throughout the period both Swedish and international exchange 
students have been using the terrestrial laser scanning 
equipment in their thesis work. Laser scanning for elevation 
modelling have been compared with traditional surveying 
techniques, measurement and modelling of different types of 
environments have been tested, including image based texture 
mapping, and accuracy performance tests have been 
accomplished. Besides thesis work using terrestrial laser 
scanning, other students finalised their thesis work at the 
National Land Survey of Sweden comparing data acquisition 
from film based digital imagery with data acquisition from 
digital imagery directly captured with a Leica ADS40 camera. 
3.2.7 Photogrammetry and remote sensing facilities 
In 2001 investments were made in four digital photogrammetric 
Delta DPS system from GeoSystem in Ukraine. Later 2001 the 
university invested in the latest technology in terrestrial laser 
scanning, a Cyrax 2500 system from Leica Geosystems. The 
university also holds an analytical Zeiss P33 sterco-instrument, 
still in use, and for the remote sensing course the University 
uses the Erdas Imagine software from Leica Geosystems. For 
image interpretation ten mirror stereoscopes are available as 
well as a wide range of aerial photographs for different types of 
analysis. In 2002 the analogue Wild A7 stereo-instrument was 
263 
dismantled and 2003 our Balplex equipment and our Wild A8 
instrument was taken apart. The Wild A8, equipped with 
encoders for digital read-out, was in use until 2001, the Wild 
A7 and the Balplex, on the other hand, had not been in use for 
many years. 
The Centre for Built Environment at the university possess one 
FLIR THV 1000 longvawe infrared camera (8-14um) to be 
mounted on a cart, a mast on a car, helicopter or fixed-winged 
aircraft. The centre also has one FLIR THV 570 (8-12um) 
infrared camera which could be used as stationary unit, 
handhold or car mounted. The infrared systems described are 
mainly used within different R&D projects for building, 
technical infrastructure and environmental applications. 
3.3 Research 
Research and development has lately focused on the newly 
invested terrestrial laser scanning equipment. Staff from the 
university have attended international events like; the 5th 
International Conference on Optical 3-D Measurement 
Techniques in Vienna, Austria 2001, the CIPA International 
Workshop on Scanning for Cultural Heritage Recording and the 
ISPRS Symposium Close-Range Imaging, Long-Range Vision 
both in Corfu, Greece 2002, and the 4th International 
Conference on 3-D Digital Imaging and Modeling in Banff, 
Canada 2003. At the CIPA Workshop in Corfu, the PhD student 
from the university, Mikael Johansson, presented his paper — 
"Exploration into the Behaviour of Three Different High- 
Resolution Ground-Based Laser Scanners in the Built 
Environment". 
During the period 2000 — 2004 the main R&D activities at 
Centre for Built Environment have been devoted to 
development of passive gas imaging methods for methane, LPG 
and biogas detection, which represent the Swedish part of an 
EU-project named "Visualisation of Gas for Utilities and the 
Environment" (VOUGE ENK6-CT2000-00054). The Swedish 
budget runs to a total about 6 milj SEK, and is financed EC and 
by the Swedish Government through the research council 
STEM. Swedish partners in the VOGUE-project are University 
of Gävle, Swedish Gas Centre (SGC), Southgas (Sydgas AB) 
Malmô Firebrigade, and The Solid Waste Company of 
Southwest Scania (SYSAV). Other EU-project partners are 
ADVANTICA (former British Gas), Italgas, Glasgow 
University, Siemens AG Germany, AOS Technology Ltd 
(AOS) UK, Electrabel Ebel) Belgium. 
In another ongoing project infrared technology has been used to 
detect temperature anomalies in a greenhouse heated by gas 
driven IR-radiators. The title of the main project is "Gas based 
infrared radiant heating in greenhouses. Aspects of energy use 
and plant development". Project partners are the Energy 
Institute LTH Lund, Swedish Agriculture University Alnarp, 
University of Gävle, Swedish Gas Centre (SGC), Kjell Ingvars 
Greenhouse Company AB, Sotuthgas Malmoe, etc. The project 
is financed by among others the Swedish Government through 
the research council STEM. 
3.4 Events 
In October 2002, a two-day seminar about terrestrial laser 
scanning was realised at the university, with more than 100 
attendees and all major developers of terrestrial laser scanning 
present as exhibitors.
