  • 8. An international research program between a French team (ThéMA) and an Algerian research team (CRASC-Oran) 4 years (2007-2010) The main objectives : - Identifying, analyzing and evaluating the recent territorial mutations of the South-Western Sahara in Algeria - Proposing a synthesis of those evolutions - Developing the interactions with the local actors - Developing a modeling and instrumented approach to propose some elements able to participate in the territorial management process 10 researchers in Geography, Architecture & Urbanism 1. The research program - Background 1. The research program Studied area The mutations Background Themes 2. The project of T.O. 3. Interactive cartography The stakes Sustainability
  • 9. The 4 main themes of the researches 1. The research program - Themes 1. The research program Studied area The mutations Background Themes 2. The project of T.O. 3. Interactive cartography The stakes Sustainability Landscape and environment Work, mobility and networks Relationship between urban and rural spaces Creation of a territorial observatory A multi-thematic approach

  • 12. 2. The project of T.O. – Structure
    • The first step :
    • Collecting the data (stat., plans,
    • Reports…)
          • &
    • Developing a cartographic interface
    • to represent the data
    • A communication tool
    1. The research program 2. The project of T.O. 3. Interactive cartography Objectives Structure
  • 13. 3. Interactive cartography - Typology Source : J.-P. Antoni et al . 2004 Typology The data 1. The research program 2. The project of T.O. 3. Interactive cartography The tool
  • 14. 3. Interactive cartography – The data Data & thematic fields already included: Macro-regional: Sahara Wilayas and municipalities Typology The data 1. The research program 2. The project of T.O. 3. Interactive cartography The tool Networks : Hydrographic, Road Raster : MNT Contextual data Administrative status and limits Demographic data Migrations data Employment data Education data Thematic data Spatial scales
  • 15. Framework MapServer is an Open Source development environment for building spatially-enabled internet applications Layers Navigation tools and interrogation of data Spatial queries 3. Interactive cartography – The tool Dynamic zoom and spatial scales v Interactive navigation Geo-visualization Caption of the map Tools to print and save the map Typology The data 1. The research program 2. The project of T.O. 3. Interactive cartography The tool PMAPPER MAPSERVER
  • 16. Population by municipalities in 1987 Illiteracy rate by wilaya in 1998 Relief, road network and administrative status Road network and hydrography Multiscale Multi-temporal Multi-thematic Interactivity
  • 17. Conclusion – future outlines To increase the quality and quantity of data, and the number of the thematic fields and the spatial scales To put online the tool to work more cooperatively and easily with the Algerian team To develop the other dimensions of the territorial observatory: documentation… To structure the spatial indicators by thematic in regards of the available data and the expectations of the local partners
