The aim of this paper is to demonstrate the utility of the methodologies based on Remote Sensing and GIS for highlighting, rehabilitation and monitoring of Land Reclamation works. Quality information means adequate and precise decision. Because GIS integrates data basis containing different information regarding the location, specifying the spatial position together with decision support data, they can be of real help in the management process of any complex company, having multiple and independent duties. GIS is a collection of hardware and software compounds and geo-referenced data, which, being used by qualified personnel is able to acquire, store, update, process, analyze and display/print information according with the needs of a specific application field of activity.The paper presents examples of GIS projects, developed in Romania, such as: LCCS Project (land cover classification system) using a methodology with a 900 classes for the land use category (highways, gas and oil networks); Land Reclamation geographic information system categorizing the land reclamation works and the relational data basis between them, taking into consideration the specific parameters to be emphasized for each work; GIS application during floods in 2005-2006, on Siret and Danube rivers, which simulated and performed a 3D virtual GIS to show the affected areas and the land configuration. Keywords: land reclamation, GIS, remote sensing, data base INTRODUCTION The aim of this paper is to present the advantage of using GIS and Remote Sensing for different kind of studies: feasibility, impact, social, economic, environmental and land reclamation investment projects. Geographical Information Systems (GIS) are part of a large category of informatics systems. Their main characteristic is that they treat information according to their position in space, using geographical/topographical coordinates to determine that position. GIS technology appeared over 30 years ago in order to facilitate complex geographic analysis that was difficult to be carried out in other existing systems (CAD, DBMS). Facilitating the analysis of spatial data taken both from classical sources (paper maps, plans, tables, etc.) and modern sources (satellite and aerial images, GPS, digital data bases, etc.), the GIS is the best solution to solve rationally and efficiently the problems regarding the management of natural resources. The applicability of GIS is, practically, unlimited, because the majority of human activities have something in common: spatial reference. Therefore, GIS is used in managing different networks (roads, railroads, pipes, cables, transportation, etc.), impact studies, surveying and mapping, etc.
