Abstract – The paper deals with the problem of comparison of Digital Terrain Models,
which were gained by diff erent technologies for the same area. In the article a test area is examined
and the data generated from laser scanning, topographic mapping and photogrammetric
evaluation of aerial images are compared. In the article the scope, the accuracy and
the reliability of the diff erent methods are compared and evaluated; the results are demonstrated
visually and in form of tables.

Abstract – The paper reports on the problem, how to optimize the the image matching process
after the aerial triangulation. The image matching algorithm is used to measure the
tie points on the adjacent photos. Recent autocorrelation implementations cannot off er or
suggest the optimal parameters. Therefore we need to investigate it before launching the
automatic image matching process for the whole photogrammetric block. In this research
the results of 3D modeling including the accuracy requirements for the ground coordinates
and exterior orientation elements are demonstrated. For testing large scale (1:8000)
scanned aerial photos were used in three diff erent pixels sizes between 7-52 microns. By
this way we can compare also the eff ectiveness and accuracy of software coming from different
companies. This comparison can be useful also for the solution providers acting on
the photogrammetric market.

Abstract – The paper reports on urban eco-environmental research activities carried out in
the West Transdanubian region in three cities (Sopron, Szombathely, and Szekesfehervar).
During the integrated environmental analyses, soil, hydrological, climatic and biological
factors were studied which were integrated in a complex GIS system. In each city, the
land cover map of the urban areas is created by using remote sensing data sources. In-situ
sampling also is carried out and these data are combined with remote sensing data. The research
topic related to the eco-environmental study area has a new innovative approach in
studying as a complex and integrated system which concluded in creation of a geographic
in-formation system (GIS) database.

Abstract – The HJ-1 A/B satellites are the remote sensing satellites used for environmental
and disaster monitoring with high spatial resolution, high time resolution, high spectral
resolution and wide coverage. This paper presents an overview of the status of the instruments
on the HJ-1 A/B platform and the urban eco-environment products derived from
HJ-1 A/B satellites’ data. The retrieval method of Leaf Area Index (LAI), one of the key urban
bio-physiology parameters is introduced. Segmentation and object-oriented processing of
