Presentation ByPrabhat Kumar, National GIS Officer, UNDP ESPEwan Oglethorpe, Data Scientist, KLL
9 August 2015
Outline of the presentation
• Initial Assessments
• Areas of Mapping Applications
• Mapping Examples
• Data Availability and Access
• Integrated Geodatabasse
Initial Assessment
• Provide situational awareness to provide urgent needs and key humanitarian priorities based on publicly available information and secondary datasets
• Generate information products (Maps, District Profiles, Sectoral Analysis. Weekly and Monthly Situational Updates)
Initial Assessment Sources
