THE GEOGRAPHICAL DIMENSION OF CLIMATE DATA IN ALGERIA

Abstract

In Algeria, implementation, monitoring and exploitation of climate data, development and dissemination of periodic publications and climate assistance to users, are tasks of the National Climatological Centre (NCC). Moreover, the effective management of this large volume of data requires the use of new technologies such as Geographic Information Systems (GIS). In this context, the aim of the present work is to develop an IT solution on the Web, based on the use of Geographic Information Systems. The approach consists, first, to design databases to store various data used (climatic and topographic) considering the functional needs such as the dissemination of data in several modes (read, download) and the possibility direct data access from remote locations. Then the choice of technology and tools to implement a mapping solution that will allow, in addition to the functionality of storage and distribution of different types of data, analysis of climate observations by using a web service whitin the WPS (Web Processing Service) standard.
