• 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)
