share. Very urgent adoption of international standards for
digital data, databases and metadatabase services is necessary.
Setting-up metadatabase services for the products of the
institute is part of the adaptation strategy.
- The advanced airborne data acquisition technology is
widely utilized in the geological survey programs. The large
beneficiary of the development of the airborne hype-spectral
spectroscopy was the geology, making possible to detect
several minerals, and elements (e.g. those causing heavy
pollution of the environment).
It is recommended, that the development action will be
concentrated mainly on the improvement of interpretational
skills and capabilities. High quality airborne remote sensing
data can be used for purposes of data mining that is the
strategy of interdisciplinary research activity.
3. ARRANGEMENTS IN THE GEOLOGICAL INSTITUTE OF HUNGARY FOR THE ESTABLISHMENT OF
DIGITAL DATABASE SERVICES
Still in 1995, the Geological Institute of Hungary as part of
the Hungarian Geological Survey initiated the nationwide
program for systematic generation of airborne data acquisition
and utilization projects including the utilization of data from
airborne geophysical sensors and optical cameras moreover
satellite-borne optical sensors at the first phase of
developments. The timing of the program proposition was ideal
as the development of geographical information systems stood
already in the centre of governmental modernization efforts at
that time (Bognár, 1998b) The National Committee for
Technological Developments (OMFB) defined the aerial
survey program as a new branch of the ongoing “3D
information national project (TNP)" (Bognár, 1998b).
The TNP project focused on the development of
topographic map-based digital database services comprising a
minimum framework of data content of the topographic maps,
including the dealing with issues of standards for digital maps,
GPS technology and even the agricultural utilization of
satellite-borne remote sensing data (crop monitoring) (Bognár
1998a.) The Hungarian government accepted the program
proposal as part of the national modernization program in
1996, and - with the support and coordination of the OMFB -
the decision supporting study under the title “Aerial Survey of
Hungary has been completed by the end of 1997 (Kardevan,
Bognar, et al, 1998).
The extension of the TNP project activity within the
framework of the Airborne Survey of Hungary project means
to include all those state data suppliers whose responsibility is
to collect data and maintain database services about the actual
state of the environment, - including the natural environment,
features and resources in addition to the built environment,
man-made objects (ordnance survey products, several kinds of
topographic maps, cadastre maps, etc.). Correspondingly, the
Geological Institute of Hungary has organized a consortium of
these digital data suppliers involving the FOMI Remote
Sensing Centre (FOMI) and the Mapping Agency of the
Hungarian Defense Forces (MH TEHI). The consortium
announced openness for extending membership:
as the main aim is to create marketable digital information
products. As next possible steps to involvement of the Institute
of Environmental Management (KGI) and the Hungarian
Regional development and Town Planning Public Service
Corporation ( VÁTI) is prepared.
The idea behind the marketing strategy of the Geological
Institute of Hungary, that the geological thematic products and
the valuable aerial survey data can be sold on the market when
they are optionally combined with each other and with
georeferenced statistical information. These products can
support governmental decisions, and used in regional and local
development programs of the industry and local governments.
The program proposal (Kardeván, Bognár et al, 1998)
emphasize the needs for concerted development of a
nationwide, integrated system of distributed digital databases,
information sharing, and a public service for ensuring easy
access to standardized metadata referring to geographic
information databases. These ideas were appreciated by the
government by the inclusion of the aerial survey program in the
governmental program package for the development of GIS
based database services including the “ Development program
for 3D information infrastructure”. This development activity
is coordinated by the Coordination Office of Governmental
Information Systems in the Prime Minister's Office (MeH IKI)
( Sikolya, 1998a; ITKB, 1998; ITKB-HUNGIS, 1998).
The discussion of the aerial survey program is in progress.
The Geological Institute of Hungary organized a workshop on
“GIS, Airborne Remote Sensing and Clearinghouse in
Hungary” as a precursor of the Symposium of ISPRS
Committee VII in Spetember in Budapest. Also the Committee
of Geodetical Sciences of the Department of the Geo-sciences
of the Hungarian Academy of Sciences has officially discussed
the “ Airborne Survey of Hungary” program. Both the
workshop's recommendations (Kardeván, 1998b), and the first
comments in the Session of the Academy's Committee
(Mélykuti, 1998) were expressed strong professional support
and hopes to make up for the lags in this field with the new
program.
As great emphasis is paid on the interdisciplinary approach
and resulting synergical effects, The Geological Institute of
Hungary established a working relationship with the working
groups of the International Society of Photogrammetry and
Remote Sensing, and the HUNAGI, The Hungarian Agency for
Geographic Information (Remetey, 1998).
Through this professional links it is hoped to speed up
integration of geological research activity with the work of the
international community of remote sensing.
4. THE STRUCTURE OF THE “AIRBORNE SURVEY OF HUNGARY” PROGRAM
The “Aerial Survey of Hungary” program designed to
consist of three packages of action programs.
A) The development of GI infrastructure. The establishment of
the domestic network of data hosts, capability improvements
for digital information (database) services
