Since 1992, implement decentralization reformin Mali has made it possible to empower populations in their own development planning. Resources distribution to local authorities requires detailed information of the constraints and the assets linked to their development. Data collected on rural area are often poorly defined, redundant or incomplete and inefficiencies for sharing due to a lack of applied standard tools. The information is too descriptive and it is difficult to extract useful one for decision making process. There is inadequate information upon which to base resource allocation decisions. The purpose of this paper is to define data that can be collected on rural municipalities or localities and handled by GIS to make information available for decision-makers, planners and beneficiaries. The data used from Malian poverty survey performed in 2001-2002 focused on the satisfaction of basic household needs. This concept is based on meeting those who lack access to basic living needs, which generally include clean water, sanitation, nutrition, primary health services, and basic education. The method used the platform of "MapGIS IGS, IIS6, Windows Server 2003, ASP.NET and MS SQL Server 2000" to develop an application GIS Web Service. Data are integrated and published as services by the platform. The product output have been tested successfully on the intranet of Wuhan Zondy Cyber in the term of interoperability and extraction of the information needed. With this tool, each local authority can be a potential collector of his own data and participates to update the database. The Web Services model of the GIS systems described provides to users, services and data they need, without having to install, learn, or pay for any unused functionalities. The extension of this standardization in all ECOWAS countries would be a great advantage regarding the sharing of geographic information between countries.
