<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Background</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">The FAO Global Information and Early Warning System (GIEWS) Workstation is a web mapping application developed by FAO with the funding of the European Commission. The Workstation gives access to food security related information and serves as main information management tool at global, regional and national levels. The aim of the GIEWS Workstation is to</FONT></SPAN><SPAN LANG="en-us"> <FONT SIZE=2 FACE="Arial">harmonize food security and early warning data within/across countries and to strengthen analytical capacity of key national institutions to support food security policy formulation and emergency interventions.</FONT></SPAN><SPAN LANG="en-gb"></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">The GIEWS Workstation includes software tools to analyze food security implications of natural and man-made disasters. These tools allow users to process historical and recent data in order to detect anomalies of environmental and economic factors (e.g. drought; excessive increase of market prices) that may reduce local populations’ capacity to access key food items. The application also includes text management tools that facilitate the compilation and dissemination of early warning messages.</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">The application handles different types of information such as remote sensing data, GIS layers, databases and texts. The GIEWS Workstation is structured as a network in which individual instances of the application (e.g. GIEWS Workstations installed in the countries) represent the nodes of this network. The network architecture is the base for information sharing. A communication tool built on a peer-to-peer technology (the same architecture used for sharing music across the Internet) regulates the flow of information among nodes of the GIEWS Workstation network.</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">The application is entirely based on Java open-source technology to avoid license constraints and to allow free distribution. The application uses several Java frameworks such as Spring, Hibernate, BIRT, Google Web Toolkit (EXT-GWT), Openlayers, GeoServer, and several others. The DBMS is Postgres with the extension PostGIS.</FONT></SPAN></P>
<BR>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Duties:</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">The selected candidate will work with the Workstation team in FAO and will perform the following tasks:</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">1) Implement the new version of GeoServer (GeoServer 2.x) into the Workstation architecture and ensure efficient communication with the other Workstation components</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">2) Improve the existing technology to link datasets (tables) with layers; improve efficiency and user friendliness of the user interface</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">3) Implement Web Map Services (WMS) and Web Processing Services (WPS) in the Workstation</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">4) Ensure that adequate security is applied to the layers and mapping functions</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">5) Improve the current functionalities for importing layers in the Workstation</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">6) Enhance the capacities of the Style Layer Editor to include 1) dynamic calculation of the layer statistics in order to define the class intervals and 2) interactive tools to manually define the class intervals</FONT></SPAN></P>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">7) Other tasks as required</FONT></SPAN></P>
<BR>
<P ALIGN=JUSTIFY><SPAN LANG="en-gb"><U><FONT SIZE=2 FACE="Arial">Qualifications and Experience</FONT></U><FONT SIZE=2 FACE="Arial">: University degree or equivalent in information technology IT skills in the development Web-based, database-driven applications combining HTML, SGML/XML, XSL, Java and JavaScript</FONT></SPAN></P>
