We wanted to explore two urban agglomerations: Iasi (47 ́09N; 27 ́37E) and Roman (46 ́55N; 26 ́54E) distant about 50 km from one another in straight line. Industrial zones are implanted in these areas. We went to explore the vertical distribution of the pollutants above these two areas. Moreover, a European road passes by the north of the two cities. We also went to track traffic emissions. Trace gas species measured during the flight were NOx, O3 and CO. Our goal is to establish the lower troposphere distribution of these pollutants in the area, in order to evaluate the photochemical production of ozone in an urban/industrial plume. The aim of our experimental strategy is to cover a horizontal and vertical dimension of the region. 1. Flight preparation To prepare the flight, we localized the urban pollution emis...

The remote sensing methods as LIDAR backscatter technique are allowing the elaboration of a high precision ( 5cm vertical and 3 points/m 2 horizontal resolutions) Digital Terrain Model (DTM) as basis of the hydrological modeling. Here is presented the airborne LIDAR technique, the usefulness of the DTM outputs for hydrologic applications and the potential application for the Romanian Danube Flood Plain assessment strategy.

REELD campaign (elaboration of a precise numerical model of the terrain over the whole Romanian Danube Plain with more than 600,000 ha distributed along 1,000 km and variable widths from 1 to 80 km large were scan from 600 m altitude) represented an opportunity for the analyse of actual geomorphology processes. After a brief introduction about airborne LIDAR technique and a short description of parameters and methodology used in the field campaign, this paper consider the application of the airborne LIDAR technique to the provision of elevation data at accuracies and spatial densities suitable to use with the current generation of high-resolution hydraulic models.

From 2004-2005 periods, localities system within north-eastern part of Romania has undergone severe transformation, some of the villages upgraded to the state of cities, without meeting the minimum conditions of legally definition, in terms of quantitative and qualitative indicators. By the use of the GIS technique and statistics, the current network of cities from Moldova (21 municipality and 33 towns) was analyzed from the perspective of 16 urban indicators. The indicators ranged from demography, access to safe water, sewerage, central heating, number of beds in hospitals, number of doctors to education facility access, cultural and sports, hotels, road access and wastewater treatment facility. All of the 16 indicators were summed and a final urban coefficient was obtained. The results were interpreted and particularly pointed out in GIS environment.

Since the 2003-2005 stage, the settlement system in North-East Romania has undergone severe transformation. Thus, some villages were raised to the rank of towns, without meeting the legally defined minimum conditions, in terms of quantitative and qualitative indicators. By using the GIS technique and basic statistics, it was possible to analyse the current network of urban settlements in Moldavia (21 cities and 33 towns) from the perspective of 16 urban indicators. The indicators ranged from demography, access to safe water, sewerage, central heating, number of beds in hospitals, number of doctors to education facility access, culture and sports, hotels, road access and wastewater treatment facilities. All of the 16 indicators were summed and a final urban coefficient was obtained. The results were interpreted and particularly pointed out in GIS environment. The conclusions emphasise that, after nearly a decade, none of the current towns meets the minimum conditions of being an urban settlement.

Deși o serie de instituții publice încearcă să copieze comportamentul spațial în propriile structuri regionale, soluția aleasă se dovedește a fi o decizie pur politică, fără o justificare științifică. În schimb, mediile private nu urmăresc caroiajul non-administrativ al acestora, structurile lor regionale fiind definitivate ca urmare a unor tendințe adaptate noilor cerințe socio-economice.

We analyzed a site with both methods: the classical topographical survey and a 3D scanning laser measurement, with a focused idea on to the second technique. The area which we survey lies in the city of Iasi and represents a thermal local power station. We tried to respect the same technical parameters for both techniques. In the end we came to the conclusion that the 3D laser scanning we used matches the application, in this case civil engineering, but, in Romania, the authorities and the legal situation are not yet prepared to accept that.
