van Genderen and T. Woldai, the sixth and final synergy of
Remotely Sensed Data Network Workshop under the title
of Synergy of Remotely Sensed Data took place at the
Auditorium of the International Institute for Aerospace Sur-
vey and Earth Sciences (ITC), Enschede. The following sci-
entific papers were presented under the chairmanship of
Dr T. Woldai:
Forest Area Mapping Based on Optical and Radar Data (B.
Koch/ T. Kremmers, Institute of Forestry, University of
Freiburg. Presented by F. Horlacher).
Analysis of Wavelet-Compressed ERS-PRI Imagery of Trop-
ical Guyana (B. Triebfuerst, C. Schneider, IPG, Freiburg/ R.
Verhoeven, Wageningen Radar Surveys) Synergy of
Remotely Sensed Data - Network Contributions by the
Department of Physical Geography of the University of
Freiburg' (H. Gossmann, C. Schneider, H. Saurer).
Knowledge-Based Interpretation of Remotely Sensed Data'
(K. Pazad, H.-J. Birkner, University of Hannover).
Compression of NOAA-AVHRR Data with a Wavelet Trans-
form' (C. Schneider, B. Triebfuerst, IPG, University of
Freiburg/ A. R. S. Marcal, R. A. Vaughan, University of
Dundee).
Forestry Information from Microwave and Optical Remote
Sensing’; ‘The JRC Geophysical Processor (GPROC)' (T.
Tares, JRC).
Synergy in Remote Sensing - What's in a Pixel?' (A. P.
Cracknell, University of Dundee. Presented by C. Cassells,
ITC).
Image Fusion Activities at the Western European Union' (D.
Munro, WEU Satellite Centre).
Under the Chairmanship of Prof. J.L. van Genderen, ITC, the
following topics were highlighted:
Geometric Aspects of Multisensor Image Fusion for Topo-
graphic Map Updating in the Humid Tropics (C. Pohl, West-
ern European Union Satellite Centre).
Laboratory Modelling of Underground Coal Fires (C. Cas-
sells, ITC).
Quality Assessment of Interferometric Data (R. Gens, ITC).
Investigations on Synergy and Complimentarity of Multi-
spectral and Anisotropy Information from MOMS-02/D2
Mode 3 Data for Land Use Classification in the Sinaloa Dis-
trict of Mexico (T. Schneider, Dept. of Land Use Planning,
University of Munich).
Geometrics Aspects of Multisensor Image Fusion for Topo-
graphic Map Updating in the Humid Tropics (C. Pohl, West-
ern European Union Satellite Centre).
Laboratory Modelling of Underground Coal Fires (C. Cas-
sells, ITC).
Besides, the network members spent considerable time in
reviewing the past three years collaboration, proposing
improvement for "Synergy Il” and planning further bilateral
and multilateral research co-operation between network
members now that “Synergy I" research network has com-
pleted its tasks. This final workshop was co-hosted by the
International Society of Photogrammetry and Remote
Sensing (ISPRS), Commission 7, Working Group VII on
Non-renewable Resources and Geotechnical applications.
Working Group VII/7 arranged two sessions at the ECO
BP'98 Symposium in Budapest. The first session was
devoted to the topics related to data integration and geo-
technical application of remote sensing, the second one
focused more on geological application of remote sensing.
The presentations covered assessments in valley areas,
underground water exploration, landslide monitoring,

investigation of neotectonic and earthquakes activities,
mineral exploitation etc.
Recommendations passed during the Workshops and
meetings held by the ISPRS WG VII/2 and VII/7 clearly
indicate the importance of this topic “Environmental
impact analysis of mining areas”, to be considered at the
ISPRS 2000 Congress. Both the developed and develop-
ing countries are affected by mining-induced environmen-
tal problems; 130 million people by coal fires in China, 40
million by a similar problems in India. The impact of mining
on the environment affects countries in Russia, Germany,
Spain, Hungary, the Czech Republic, Slovakia, Philippines,
USA, Canada and others.
A special conference of the NATO Advanced Studies held
in Hungary, 6th-19th September 1998, managed to bring
together about a hundred experts from 39 countries to dis-
cuss this topic under the chairmanship of dr. Péter Karde-
van. The participants unanimously agreed that the impact
of mining on the environment is too big to be disregarded
lightly and recommended all participants to work on this
problem. Major research and collaboration programmes
were proposed on topics such as the impact of mining,
environmental impact modelling and site assessment, RS,
GIS, data fusion and integration, modelling, hazard zoning
(seismic hazards, landslide hazards, mountain hazards),
risk assessments, sensitivy analysis — topics which can be
used as key-words. Ecological assessment of reclamation
activities, monitoring of long-term development of these
areas. Change in the socio-economical structure in an
area, especially in open-cast mining region. Additional
subjects to be covered: toxic waste and its impact on
health, groundwater pollution, soil degradation, environ-
mental geoindicators and geoindices, air, water and soil
pollution as a result of mining, mining-induced urbanisa-
tion, illegal mining, assessment of lowering the groundwa-
ter — influence on the ecosystems in the surroundings,
mineralogical classification of the tailings and spoiled sed-
iments, assessments of the acid mine drainage, influence
on the surface waters, hydrochemical analysis of the lakes
etc.
The main topics in the preparation of the WG VII/7 for the
ISPRS Congress will be related to Remotely sensed data
and GIS applications in non-renewable resources man-
agement; Field data capture techniques, data fusion and
modelling; Risk assessment; Geological hazard zoning
and mapping (volcanic, seismic); Mountain hazards; RS
and GIS in environmental geological applications; Synergy
of remotely sensed data; Predictive modelling in geomor-
phology for environmental impact analysis; Geoenviron-
mental modelling; Integration of airborne and spaceborne
RS data, including hyperspectral data; Geophysical and
geochemical assessment in mineral exploration; Develop-
ment of software dedicated to resources management;
The role of the satellite industry, software developers etc.
versus the end user in the year 2000. Invited co-operating
ISPRS WGs: VII/2, VII/3 and VII/6. Co-operating organisa-
tions/institutions planned: ITC — Geological Survey Divi-
sion, MAFI and others.
Additionally, special emphasis will be given to the theme
mining and its impact on the environment i.e. the applica-
bility of remote sensing and GIS to sustainable develop-
ment in environmentally sensitive mining areas. This theme
includes: modelling of mining impact and site assessment,
