Abstract

GIS (Geographic information System) techniques, characterized by high accuracy of mapping and measurement, prove to be a competent tool in morphometric analysis. The main goal of the study is to analyze the hydrographic network in linear form (vector) by overlaying databases from different periods (vector layer made in 2003 and layer made in 2017) for a regional case study within Southwestern Romania. The database organized in layers aims to reproduce characteristics of the drainage network: the cartographic maps scale 1: 100.000, Geo-referenced in ArcGIS 10.4); the first version of the hydrographic network used in the first River Basin. The results of this analysis will be concentrated on the length of the river network correlated with the two layers and also on the relief based on a DTM (cell size 5×5 m) within the study area. The relevance of the discussions lies in highlighting the differences appeared over time regarding the hydrographic network spatially using GIS based quantitative morphometric analysis.

Using G.I.S. for identifying mobility problems in Milan city

Sorin AVRAM, Ştefan NEGREANU

Abstract: Becoming an indispensable instrument in the integrated management of settlements, GIS has become very useful for territorial organization, the fluidization of the traffic representing the priority problem from both the environmental and the social costs point of view. Thus, through various informatical systems and mathematical modeling, a series of thematical layers can be realized, taking into account different variables which enter the equation of the territorial mobility, which, once overlapped, can generate extremely precise information regarding the neuralgic points for mobility, the hours with congestions and the road arteries on which they take place, the finality of information hence obtained being integrated in the territorial organization planning that will solve the main town-planning problems taking into account the valid legislation.
