First steps in Romania converging toward the GlobalSoilMap specifications
A National-scale assessment of the Topsoil Clay Content Map of Romania derived from the LUCAS survey

The clay consists of the tiniest particles of soil, which have a considerable amount of physical and chemical activity with influence on water and nutrient cycles, observable over several scales. Therefore, the Global Soil Map Project (GSM) has included clay content among the key properties estimated across the world at 100 m resolution. Subsequently, in 2015 the Joint Research Centre (JRC) of the European Commission produced a clay content map of

Soil legacy data rescue via GlobalSoilMap and other international and national initiatives

Legacy soil data have been produced over 70 years in nearly all countries of the world. Unfortunately, data, information and knowledge are still currently fragmented and at risk of getting lost if they remain in a paper format. To process this legacy data into consistent, spatially explicit and continuous global soil information, data are being rescued and compiled into databases. Thousands of soil survey reports and maps have been scanned and made

Monitorizarea culturilor agricole cu ajutorul datelor culese de sateliţi de rezoluţie spaţială medie
Satellite derived leaf area index from SPOT time series, In: Proc. Int. Geoscience and Remote Sensing Symp. IGARSS’03,Vol. 1, pp. 155-157
Evaluation of SPOT/HRV data over temporal series. In Proc. of Geoscience and Remote Sensing Symposium, 4, pp. 2209 – 2211. IEEE, 2003.

The objectives of this study is to evaluate SPOT/HRV data as acquired during the ADAM project. Between October 200 and July 2001, 39 SPOT/HRV images have been collected. They correspond to SPOT 1, 2 and 4. The consistency between images was analysed over a 10×10 km2 area of agricultural crops located near Bucharest in Romania. The day to day signals show significant variations that could not be easily interpreted in terms of the surface characteristics.

Surface soil moisture estimation from SAR data over wheat fields . In Proc. of Geoscience and Remote Sensing Symposium, 4, pp. 2885 – 2887. IEEE, 2003.

Surface soil moisture estimation from SAR (ERS-2 and Radarsat) images was investigated using the "water-cloud" model. It was verified that the "water-cloud" model can adequately represent the backscattering coefficients over winter wheat fields, during the entire growing season, as a function of canopy water content and surface soil moisture.

Evaluation of remote sensing data for urban planning. Applicative examples by means of multispectral and hyperspectral data. In Proc. of Remote Sensing and Data Fusion over Urban Areas , 1, pp. 201-205. IEEE, 2003.

Most city planners and managers already recognize that urban areas require careful design/re-design and considered management, based on resource sustainability criteria. Involved aspects range from protection of natural and human resources, wise energy and water management, reduction of air pollution and traffic control, health and well-being of population, safeguard of cultural heritage, comfort standards in residential districts, industrial production,

Relationship between leaf area index, biomass and winter wheat yield obtained at Fundulea, under conditions of 2001 year. In:Romanian Agricultural Research, 19-20, pp. 21-29, 2003.

Several data of the ADAM (Assimilation of Data within Agricultural Models) project were used to establish the relationships between agronomic variables of winter wheat. During the campaign 2000-2001, ten calibration units from seed production farms of A.R.D.I. Fundulea were selected based on several factors of variation, such as: the cultivar (Dropia and Flamura 85); the preceding crops, soils with different microtopography and nitrogen fertilization.

Sistemul Informatic Geografic al Resurselor de Sol ale României “SIGSTAR-200”: Metodologie de realizare şi principalele tipuri de aplicaţii. In Proc. of the XVII-th National Conference of Soil Science, Vol 34A, pp. 439-449. National Soil Science Society of Romania, 2004.

The Geographic Information System of Soil Resources "SIGSTAR-200" was developed based on the information contained in the fifty tiles constituting "The Soil Map of Romania at the scale 1:200,000", tiles published from 1964 to 1994. During the development of SIGSTAR-200, the mapped information was updated in accordance with a unique legend published in 1994. SIGSTAR-200 is intended for the administrative levels (ministries and county departments)
