THE essence of spatial data can not be marginalized as no any Planning undertaking needs no spatial data. All GIS based approaches for open source data can be vital in planning for saving the vulnerable population. NOW,its a time to expose the vulnerable population’s location so that the humantarian efforts can follow up. By the time being. many of LDCs governments seems to invest less but there comes a time ahead when this field will be vital to them. AS an Urban Development and Environmental Management Planner, i do encourage all mappers and students especially those not taking SPATIAL PLANNING DISCIPLINES to invest much in GIS KNOWLEDGE.
