- Standardization of satellite-borne and airborne survey
data, image- and map products of the GI- sector.
- Creation of modern digital topographic database
- Widespread creation of metadata for and auditing of
the existing database systems and services,
- the elaboration of a unified system of regulations
and legal background of data services
- establishment of organizations of interdisciplinary
coordination
B.) Data acquisition projects
- Digital ortophotos over the whole country. Initiated
by the Mapping Agency of the Hungarian Defense Forces (MH
TÉHI) as a self-contained project for cartographic purposes,
and offered also for extended utilization as part of the airborne
survey program.
It is recommended to accomplish surveys within
short period of time (e.g. 2-3 years at the maximum) as the
high resolution colour photos can be used for purposes of
environmental protection. It can be regarded as 0-
environmental state of the country and subsequent monitoring -
including satellite-borne data of less resolution - can be based
on this airborne photos. Merging airphotos of high geometrical
resolution with multi-channel (spectral) satellite images of less
geometrical resolution is highly recommended.
- Surveys with geophysical sensor.
It is recommended that this survey will be
structured, and implementation will be in line with the support
activities of concession prospecting. (Brezsnyánszky-Füst-
Kardeván-Nádor, 1998; Füst 1998) Data packages for oil and
gas exploration or building material can be compiled and sold
in conjunction with tenders for concession prospecting rights.
The time scheduling and linkage of concession and airborne
geophysical data acquisition activities is essential. The data
acquisition project should be linked with state-of-the-art
technology transfer especially in the field of interpretation.
- Pilot project for the utilization of airborne hyper-
spectral spectroscopy on thoroughly selected areas (Kardeván,
1998).
It is recommended to use European Union Large
Scale facility DAIS for hype-spectral data acquisition. The
project should demonstrate multi-utilization of spectral data,
and the benefits of data sharing.
C.) Application projects. Based on Cost/Benefits analysis
introduction of new technologies, development of training and
education, application of established methods.
The study Aerial Survey of Hungary (Kardevan, Bognar et
al, 1998) comprises numerous suggestions for possible
applications of the new airborne remote sensing techniques.
Some examples are:
- Remote sensing program for the establishment of
Defensive Information System (initiated by the Mapping
Agency of the Hungarian Defense Forces (MH TÉHI)).
- Compilation of airborne geophysical data packages for
supporting the concession prospecting activity in oil and gas
exploration. (Initiated by the Geological Institute of Hungary
(MAFI)).
- Monitoring of salt soil regions. (Initiated by the
Research Institute for Soil and Agrochemistry (TAKI))
- Complex environmental assessment in the region of
Mecsek Mountain. (Initiated by the Mecsek Ore Prospecting
Company (MEV), the Regional Ofice of Baranya County of the
Environmental Protection Inspectorate, the Regional Office
Baranya County of the Directorate of Water Management,
Geological Institute of Hungary (MÁFI)).
- Protection of water resources. (Initiated by the
Ministerial Commissioner for the Regional Development of
Velence Lake Region)
- Prevention of emergency situations in many cases
(initiated by the authors of the Study Aerial Survey of
Hungary)
1. ACTUAL ARRANGEMENTS OF MÁFI FOR THE DEVELOPMENT OF GI INFRASTRUCTURE.
Mentioned are here only the preparation within the frame
of the activity of the GIS working group of MeH IKI. As an
important step forward MÁFI is taking part in the pilot project
for establishing standardized metadata services in the public
administration at this starting phase (Sikolya, 1998b).
Members of pilot project are those of the GIS working group of
MeH IKI. The subject of the pilot project is among others
testing of FGDC metadata standards (Federal Geographic Data
Committee, US. Geological Survey (USGS.)), that will be
soon the pre-standards of ISO.
REFERENCES
Through the professional links between the USGS. and
MAFI a know-how transfer referring to the establishment and
maintenance of geo-spatial clearinghouse node can be
accomplished in the future according to plans. Due to the broad
overlapping of CEN and ISO standards and the expectation of
the convergence of several standards, MÁFI hopes to actively
take part in the European Union' programs for GIS metadata
services at an early phases through the acquisition of
experiences with FGDC and CEN standards. Future MÁFI
plans include joining Joint Research Institute's future FGDC
clearinghouse gateway project.
