ABSTRACT:
The paper summarize the main concepts and principles of the national development program "Airborne Survey of Hungary"
discussing them also from the point of view of the introduction of airborne remote sensing methods in the field of geology,
geophysics and geochemistry in Hungary. Pertinent ideas have been elaborated and collected in the decision supporting report
prepared for the Hungarian government under the title: *Airborne Survey of Hungary" with the coordination and support of the
National Committee for Technological Development ( OMFB) and the Geological Institute of Hungary (MÁFD.
The authors will discuss the role of the geological sciences in understanding and solving problems of environmental protection.
The combination and integration of GIS based statistical data with those determining the actual state of environment (airborne or
remote sensing images) moreover those characterizing the surface scenery and sub-surface region of the environmental processes
(thematic geological, soil, etc. maps) will result in new marketable digital geo-spatial information products. As an application
example of data sharing, the compilation of airborne geophysical data together with the geological data packages for purposes of
mineral and oil exploration moreover for alternative utilization will be discussed. Examples for joint interpretation of satellite
images and geophysical parameter maps will be shown as well.
A proposal for airborne hyper-spectral multidisciplinary pilot project is mentioned for determining contamination from
hydrocarbons, heavy metals, the heath conditions of vegetation
mapping soil, and minerals. The need for the availability of hi
, the canopy, the DEM, detecting minerals, chemicals, salts,
gh quality data will be strongly emphasized as one of the main
targets of governmental expenditures in these fields. The role of data mining and knowledge management will be mentioned as
well.
Efficient development of GIS databases calls for concerted actions of different sectors of the government. The framework of
this is offered by the governmental propositions for the development of the geo-spatial data infrastructure. The authors will suggest
the establishment of geo-spatial clearinghouse node in MAFI and the creation and dissemination of metadata standards for geo-
databases accessible for Internet search engines.
1. INTRODUCTION
The subject of this paper is to give short review of the
conceptional framework and purpose of the “Airborne Survey
of Hungary” program, that is being prepared as part of the
modernization program of the country, and summarized in
the study prepared with the support and . The specific area
under discussion is part of a wider range of activities for the
development of geo-referenced and geo-spatial digital
database services.
On the one hand, the aerial survey program serves certainly
as part of an over-all modernization approach, giving
appropriate response to the challenges of the forthcoming
information society and to the effects of the globalization in
Hungary. Thus, it is part and parcel of the governmental
program package under preparation comprising a series of
projects for the development of GIS database services.
Moreover it is a direct continuation of same efforts started
already in 1992 (Bognar, 1998). Henceforth, its concepts and
recommendations are closely related with those of the
numerous white papers or blue books published on the issues
of information society ( White House,1996; Japanese
Telecommunications Council, 1994; The Council of the
European Union; 1994; UNESCO, 1996;
OECD,1996), that have been obviously taken into
consideration when formulating the Hungarian strategy for the
development of geo-spatial infrastructure.
However, there are a lot of specific problems that
characterize the small-sized CEC countries trying to fill in the
gaps in the European and domestic levels of technology and
social organization (Varga, 1998). Undoubtedly, the engine of
all developments should be the strong wish of the governments
and nations in Central- East Europe to access the EU. If, the
Bangemann report emphasizes the pressing time to do
measures for transition, how urgent the necessary actions are in
these countries lagging behind in the competition with the EU
countries in the last decades?
On the other hand, the aerial survey program represents a
possible response to the actual adaptation problems, that the
geological survey institutions all have in common in Europe.
Corresponding to the spirit of the study referred above, we
use the term “aerial” in this paper in a broader sense, wishing
to express the tendency, that both airborne and satellite-borne
sensors are necessarily involved in such “Earth Observation”
survey programs complementing mutually each other.
