The first Bulgarian capital – the medieval town of Pliska is one of the most significant
archaeological sites in Bulgaria. Non‐destructive remote sensing and GIS methods were
combined with technologies for archaeological terrain surveys and modelling of the – Pliska and the National Historical and Archaeological Reserve Kabiyuk, together with a team from
the National Institute of Archaeology with Museum – BAS (11, 12, 13). The ongoing work within a project proved that the integrated application of remote sensing and ground‐based data are very useful in preventing turning regions into endangered archaeological structures areas (14).
It was found that the narrow‐band VIs from EO‐1/Hyperion, field spectroscopy data measured with ASD HH FS granted by ASD Goetz Instrument Support Programme 2011, the broad band VIs from very high spatial resolution (VHR) multispectral satellite data from

BulArgo a Bulgarian research infrastructure as a component of the Euro ARGO network
The purpose of the project is to develop a new national marine research infrastructure for in situ observation in the Black Sea based on autonomous profiling floats. This represents the Bulgarian contribution to the EuroArgo network, which is a part of the Global Argo programme. BulArgo is a project funded by the Bulgarian National Science Fund (NSF) and the Ministry of Education, Youth, and Science (MEYS). The project partners are: the IO‐BAS; the Department of Meteorology and
Geophysics at the St. Kliment Ohrdiski University of Sofia; the NIMH‐BAS.
Under the BulArgo program, three Argo floats were deployed in the Black Sea in the Bulgarian EEZ
during the cruise of the Akademik research vessel (R/V) on 17‐19 March 2011. Each float measured
temperature and salinity between the surface and a pre‐determined depth (1500 m) at intervals of 5 days. As a result of this study, an interesting variation of the Black Sea halocline depth in the salinity
data gathered from Argo float 6900804 (Emona) was found. The trajectory of the float is shown in
Figure 6 (a) and the data in the 200 m thick layer are shown in Figure 6 (b). Correlation between sea water salinity and Jason’s altimetry data can be noticed as well, Fig. 6 (c) (32).

Trang 16At the Faculty of Geodesy of the University of Zagreb in 2012, the following curricular activities
related to remote sensing were held: compulsory programmes Remote Sensing (undergraduate
studies, 5th term) and Advanced Remote Sensing (graduate studies, 2nd term), and facultative
programmes Applied Remote Sensing (graduate studies, 1st term) and Remote Sensing – PROJECT
(graduate studies, 2nd term). Remote sensing research carried out at the Faculty of Geodesy of the
University of Zagreb are related to the FP7 project Toolbox Implementation for Removal of
Anti‐personnel Mines, Submunitions and UXO (TIRAMISU), which commenced on 1st January 2012 and should last (provided the research results prove worthy of a follow‐up) until the end of 2015. The project‐related research aims at improving (technically and methodologically) the present operative Advanced Decision Support System, in order to assist humanitarian demining experts in making decisions regarding defining the mine suspected area. The Faculty of Geodesy of the University of Zagreb and the Croatian Mine Action Centre – Testing and Training Centre (with the latter, the co‐owner of the said System, the Agreement on Technical Cooperation was signed) are two partners
in the consortium of a total of 24 partners from 11 European countries.
The Chair for Photogrammetry and Remote Sensing of the Faculty of Geodesy participated in the 22nd International Society for Photogrammetry and Remote Sensing (ISPRS) Congress, which was held 25th August – 1st September 2012 in Melbourne, Australia, with a paper Increase of readability and
accuracy of 3D models using fusion of Close Range Photogrammetry and Laser Scanning, authored by
M. Gašparović and I. Malarić. A brief report by M. Gašparović may be found on http://fodi.geof.hr/images/e‐knjiznica/izvjesca/izvjesceisprs2012.pdf. A new Order on Air Imaging was passed (procedures for acquiring approval for photographing have been harmonised with European norms).
The Geology and Geophysics Section
(Report by: Ivan Hećimović)
The members used remote sensing methods respecting thereby the set organisational, financial and market rules. At the Croatian Geological Survey, the application of remote sensing methods was
focused on the implementation of the programme The Geological Map of the Republic of Croatia,
which encompasses eight scientific projects. These are: the Basic Geological Map of the Republic of Croatia in scale 1:50.000 as the largest project; the Basic Hydrogeological Map of the Republic of Croatia; the Basic Engineers' Geological Map of the Republic of Croatia; the Basic Geochemical Map
of the Republic of Croatia; the Geothermal Map of the Republic of Croatia; the Structural‐Geomorphologic Map of the Republic of Croatia; and the Tectonic Map of the Republic of Croatia. The Ministry of Science, Education and Sports financed all the projects. The remote sensing methods
application is further articulated through the bilateral Japanese‐Croatian project Risk Identification
and Land‐use Planning for Disaster Mitigation of Landslides and Floods in Croatia, which focuses on
Trang 17tral library database. Taking the gained results into consideration, a quick and economic application
of multi‐spectral and hyper‐spectral imaging has proved necessary not only for the purposes of forest protection, but also for the needs of other scientific disciplines.
According to the plan for the year 2012, research aimed at inspecting the possibility of applying digital aerial photogrammetric images in various spatial resolutions for the purposes of forest inventory was carried out. The data acquired by classic terrestrial methods of forest inventory and the data acquired by photogrammetric methods were compared and analysed for the area under examination. To this aim, field measuring, aerial imaging, photogrammetric measuring, subsequent control field measuring, as well as statistic processing and analysis of the results were performed.
In isolated sections, a systematic sample of exemplary surfaces equalling to approximately 2 % of the total section surface were positioned. Exemplary surfaces had the shape of a circle with radius of either 8 or 12 m, depending on the stand density. On exemplary surfaces, chest diameters of all trees were measured, as well as were the heights of a defined number of trees, on the basis of which the height curves for all tree species were developed. Furthermore, qualitative stand/section description per cadastral plot was carried out. In the examined area, multi‐spectral (RGB and NIR) aerial photogrammetric imaging supported by GPS/IMU technology was conducted. Infrared and colour digital aerial photogrammetric images in spatial resolution of 10 and 30 cm are a result of aerial imaging. On the basis of digital aerial images, for the needs of the examined area, the digital relief model (DRM), the digital height model (DHM) and the digital orthophoto were developed in the digital photogrammetric station. On the basis of digital images in spatial resolution of 10 cm, DOF1 (pixel 10 cm, scale 1:1000) was developed; whilst on the basis of digital images in spatial resolution
of 30 cm, DOF5 (pixel 50 cm, scale 1:5000) was developed. Stratum delineation (stand isolation) was carried out in the stereo‐model, on the digital photogrammetric working station Racurs Photomod. In thus delineated strata in digital photographs, a net of systematic samples identical to the field sample of exemplary surfaces was positioned. The photogrammetric measuring of specified tree and stand elements, was carried out in the stereo‐model. On photogrammetric surfaces, tree heights, the width of tree crown, number of trees, and tree species were measured and evaluated. DRM and DHM were used for tree height evaluation. Based on the already known and the newly established correlations, tree chest diameters and other important parameters were defined in order to be compared to the terrestrially measured values. Regression models of the evaluation of chest
Trang 18diameters of major tree species including the diameter of tree crown and tree height as independent variables were prepared. Considering the results of the regression analysis, as well as the graphic and analytic testing of every individual model, it might be concluded that the prepared regression models could be used for evaluating tree chest diameter using the method of photogrammetric imaging. The comparison of the results of economic division confirmed that there existed no statistically significant differences; this was further confirmed and justified by stand isolation carried out through the photointerpretation of aerial images. By measuring the structural stand elements using various methods, no statistically significant differences were found in connection with photogrammetrically evaluated tree heights, tree basal areas, and volume at section levels.
The health condition of the trees in the City of Zagreb area was determined by applying remote sens‐ing methods. To this purpose, imaging aiming at developing satellite images of high spatial resolution – WorldView 2 (0.46–0.52 m panchromatic or 1.84–2.08 m multi‐spectral) was ordered. The satellite images of such a high spatial resolution enabled the interpretation of the damage of the major tree species in the Park Forests of the City of Zagreb, and the development of the theme maps of spatial damage distribution. In order to conduct the assessment of the health condition of two diagonal trees closest to the centre of the raster, out of the delivered satellite image, a digital infrared colour orthophoto of the area under examination and a systematic sample of the net of points 25 x 25 m were developed. Based on the results of the interpretation of satellite images, damage indicators were calculated (damaged; medium damaged; damage index; mean damaged of considerably dam‐aged trees) for individual tree species, for all interpreted species together and in total for the entire imaged area.

project, in which Croatia has been participating since 2004. The project consortium encompasses,
apart from the Croatian Meteorological and Hydrological Service, meteorological services from
Austria, Germany, Finland and Portugal. The project included drafting computer‐learning material for
interpreting satellite images and their linking to other meteorological data; and organising on‐line
training and seminars in satellite meteorology and satellite data application. In 2012, the working
radar stations (Puntijarka, Varaždin, Trema, Stružec, Gorice, Bilogora, Osijek and Gradište). The S
wave radars were used, and the measurements were carried out when necessary and when Cb
clouds appeared. The results were published in the documents issued by the Croatian Meteorological
Trang 20and Hydrological Service. Dr. Sc. Bojan Lipovšćak and Zvonko Komerički participated in the work of the European Radar Conference.
Lightning measurements
The LINET system lightning data were used in everyday forecast‐related work and in the scientific research on convective phenomena. Hence, in 2012, the lightning data were compared to the occurrence of overshooting convective CB‐cloud tops in order to define the characteristics of lightning in such situations. P. Mikuš and N. Strelec Mahović made the preliminary research results
public at the EUMETSAT conference in the form of poster entitled Characteristics of lightning activity
in deep convective cloud with the overshooting tops. The lightning data were further used in the
research aimed at estimating the accuracy of linking the satellite atmospheric instability indices to the convection development represented by the lightning data. Z. Bahorić published the research results in his graduation thesis. The follow‐up of both researches is underway.

(Report by: Bartul Šiljeg)
The analysis of web search engines and online surveys (ARKOD, Geoportal, Google Earth) continued with the aim of analysing the known archaeological localities and discovering new ones. B. Šiljeg and
H. Kalafatić photographed the Slavonian area between Čepin and Đakovo using a series of oblique images, which resulted in discovering new localities. V. Glavaš performed the photographing of the Velebit area; while on Hvar, the Field of Starigrad and the entire island are regularly imaged. Within
the scope of ERASMUS, an intensive programme entitled Ditecur (Digital technologies in cultural
landscape research) was held in Zagreb 30 January – 12 February 2012, where B. Šiljeg lectured on Aerial archaeology in Croatia. Two Croatian experts took active part in the International aerial archaeology conference AARG 2012 held 13–15 September in Budapest. V. Glavaš held a lecture

Research
Education and research are closely intertwined at ITC. From 1 January 2010 the research will not be managed and coordinated by a research institute ‐ as is customary at UT ‐ but by the faculty dean who has, to all intents and purposes, the same powers as a director of a UT research institute. But in
no way will ITC be an odd‐man‐out. The new rector, Professor Tom Veldkamp, certainly expects that integration with UT will raise the standard of research at his faculty even further. As UT staff members, the professors will be accorded independent rights to confer doctorates. In 2012 a total of
22 researchers received their doctorate degree from UT‐ITC.
As an example below are activity overviews for two departments of UT‐ITC namely the earth observation science department and the earth systems analysis department:
The department of earth observation science at ITC has a long record of knowledge and knowledge exchange in the domain of remote sensing. The focus is in the remote sensing domain at present on multispectral images, radar images, and lidar imagery. As the latter is mainly airborne or terrestrial, the below summarizes some of the recent achievements in satellite remote sensing. To a small degree the department also addresses hyperspectral images. Key issues are at this stage the following:
Superresolution mapping (SRM). With SRM efforts are successfully done to be able to identify within pixel information. On the basis of classification and segmentation techniques class proportions within pixels can be defined. To some degree it allows to develop and apply subpixel mapping.
Object based segmentation and classification techniques are being applied successfully and
at an increasing range of applications. Important questions in our research are issues of spa‐tial data quality of the identified objects. Fuzzy and random set techniques are used for that purpose.
Multitemporal remote sensing has been applied to various studies. Critical aspects such as correspondence of flight lines, matching of resolution and changes between the seasons are taking into account.
Spatial interpolation of missing values. Serious work is done to fill the gaps in images. Starting with the obvious, small gaps, currently techniques are developed and applied to interpolate larger patches of missing data.
Use of remote sensing imagery in deterministic models. The combination of satellite images with field data and deterministic models has made recently a good step forward, where Bayesian networks have been applied successfully in the difficult modeling of GPP and LAI.
Spatial data quality issues are interesting an intriguing in the domain of remote sensing. Starting with the MAUP, currently attention is shifting towards the IFOV, registration precision and the effects of distortions at the earth surface and the atmosphere on derived products.
In terms of applications, a wide range of topics is addressed. Particular attention has been given to identifying trees in the city, to LAI and related Biomass determination, whereas at present steps are made towards hydrological modeling.
The Department of Earth systems analysis has recently launched a new research programme: 4D‐EARTH. Earth scientists at the Department of Earth Systems Analysis (ESA) strive at providing reliable earth science information that is used to understand and model earth dynamic processes in all three dimensions and variation over time. The research aims to find answers to sustainability and economic development issues: depletion of mineral resources and environmental effects of exploitation, geothermal energy, and mitigation of natural disasters caused by processes in and on the earth surface. The departmental research is embedded in a programme called 4D‐EARTH
Trang 23supported by two chairs: Sustainable Energy and Georesources (Prof van der Meer) and Natural
Hazards and Disaster Risk Management (Prof Jetten).
Dealing with such issues and problem areas requires that adequate spatial and temporal information
on earth systems and processes is available and accessible. A good understanding of the earth systems and processes, their dynamics in time and space, and their influence on society is necessary.
We combine this understanding with state of the art know‐how in remote sensing and GIS technologies, including spatio‐temporal process modeling, predictive modeling and geostatistics, object oriented remote sensing and contextual filtering, hyperspectral remote sensing, airborne and spaceborne geophysics and geochemistry.
Trang 24The Centre for Geo‐Information (CGI) is a joint undertaking of the laboratory of Geo‐Information
Science and Remote Sensing (http://www.geo‐informatie.nl) of Wageningen University and the department of Geo‐Information (http://www.wageningenur.nl/en/Expertise‐Services/Research‐
Institutes/alterra/About‐Alterra/Teams‐Alterra/Earth‐observation.htm) of Alterra. The Centre for
Geo‐Information comprises two full chairs: Geo‐Information Science with special emphasis on GIS,
Prof. dr. ir. A.K. (Arnold) Bregt, and Geo‐Information Science with special emphasis on Remote Sensing, Prof. dr. M. (Martin) Herold. In addition, one chair is affiliated with the Centre, namely the
former remote sensing chair holder Prof. Dr. Michael Schaepman, who is now at the University of
Zurich. The Centre focuses on education, fundamental research and applied research within the
This trend is reflected in the activities of the GRS‐group of Wageningen University that includes
about 40 researchers. Research always has a fundamental character, but with a clear link to the
Wageningen application fields. Research activities include spatial data infrastructures, spatial data
modelling, geo‐visualization, quantitative remote sensing, and national, European and global scale
land mapping and monitoring. Staff is working in collaboration with various national and international research institutions and organizations, including the government and private sectors
to provide research in geo‐information science in order to support policy development and the design and management of rural areas at various scale levels.
