Technical Commission I: Sensors, Platforms and Imagery
George Joseph, Commission-I President, (India)
Secretaries:
Shri A.K.S. Gopalan, India
Shri V. Jayaraman, India
1. Introduction
Technical Commission - | deals with sensors, platforms and
imagery, with the following terms of reference.
Terms of Reference
* Planning for aerial and space missions
* Design, construction, testing, installation and calibra-
tion of analogue and digital imaging sensors
* Design and performance of data reception and pre-
processing systems
* Geometric and radiometric properties of image data
and quality standards, and factors (environmental and
others) affecting data quality
* Technical systems for recording sensor data, film scan-
ners and auxiliary data (time, position, attitude, etc.) and
media (film, magnetic, optical, etc.)
* Pre-processing techniques to generate data suitable
for analysis and measurements (radar image synthesis,
multisensor integration, radiometric and geometric
corrections, etc.)
The activities of Technical Commission - | are carried out
through five Working Groups as given below:
WG-1 - Sensor parameter standardisation and calibration
Chair: Dr Manfred Schróder, Germany
Co-Chair: Dr Alan Belward, Italy
WG-2- Pre-processing, Archival and Dissemination of
Image data
Chair: Dr Dan Rosenholm, Sweden
Co-Chair: Dr Jolyon Thurgood, USA
WG-3 - Sensors and Platforms for Topographic Survey
Chair: Dr Karsten Jacobsen, Germany
Co-Chair: Dr T. Natarajan, India
WG-4 - Microwave and optical sensors for geospheric-
biospheric studies
Chair: Dr Jean Louis Fellous, France
Co-Chair: Dr John Miller, Canada
WG-5 - Advanced Platforms and Sensors
Chair: Mr Takashi Moriyama, Japan
Co-Chair: Mr K. Thyagarajan, India
2. Symposium, Workshops, Meetings, Congress
2.1 Symposium
The ISPRS TC-I organised the International Symposium on
‘Earth Observation System for Sustainable Development’
from February 25th-27th, 1998 at Hotel Atria, Bangalore,
India.
The technical parogramme was organised in eleven ses-
sions, including the theme session ‘Earth Observation
International Archives of Photogrammerty and Remote Sensing. Vol. XXXIII, Part A. Amsterdam 2000.
System for Sustainable Development'. The other sessions
covered various aspects related to sensors, platforms,
preprocessing, etc. There was also a special session on
CEOS. 46 technical presentations were made in these ses-
sions. The papers were from Canada (2), Germany (18),
India (19), Italy (2), Japan (2), Korea (1), The Netherlands
(1), Switzerland (3) and USA (5).
173 participants from 29 countries participated in the
deliberations. The delegates were mainly from space
departments (98), industry (25) and academia (50).
Proceedings containing forty technical papers was also
published at the time of the symposium. The proceedings
are prised at 30 Pounds Sterlings and are available at the
RICS Books (RICS Books, Surveyor Court, Westwood
Way, Coventry, CV4 8JE, United Kingdom).
Commercial presentations were made by Radarsat Inter-
national, Canada on the Radarsat Mission, operations and
programme and Intergraph, ISA on Data handling and
information, dissemination for sustainable development.
A technical exhibition was also organised along with the
symposium. Seven exhibitors from USA, Canada and India
participated.
Two pre-symposium tutorials, on ‘Pre-processing of Image
data’ and ‘Electro-optical Sensors for Remote Sensing’,
were organised on February 23rd-24th, 1998 at ISRO
Headquarters, Bangalore, India. The faculty was drawn
from India, Germany and Japan. The tutorials were
attended by 49 participants from 21st countries.
2.2 Workshops
The workshop “Sensors and Mapping from Space” was
organised jointly with the working groups 1/1 “Sensor Para-
meter Standardisation and Calibration of Space Sensors”,
1/3 “Sensors and Platforms for Topographic Survey” and
IV/4 “Mapping Using High Resolution Satellite Imagery",
from September 29th up to October 2nd, 1997 at the Uni-
versity of Hannover, 36 papers were presented and pub-
lished as number 17 of the "Publications of the Institute for
Photogrammetry and Engineering Surveys of the Univer-
sity of Hannover". 85 participants from 30 different coun-
tries took part. The workshop covered not only the area
mapping from space, including the used and coming sen-
sors, but also the new airborne sensors like laser scan-
ning, 3-line sensors and also the sensor orientation by IMU
and GPS. The major outcome was that new systems are
available and space systems with very high resolution
should be available soon, which could open up new
avenues in mapping.
The workshop ‘From Producer to User’ was jointly organ-
ised by WGs 1/2 "Pre-processing Archival and Dissemina-
