3.GapsandChallenges

Identification of flooded villages• DEM resolution not adequate  (z = 5m), hiding low lying villages 

• Tree cover and building materials density hiding surface water

Image: MAEU Myanmar, 2015

Image: FAO Myanmar, 2018

Image: Maung Maung Than, 2018

3.GapsandChallenges• Possible under‐reporting

• No capture of flash floods• Image not always taken at the peak of the flooding

• No platform for collection of field observations• No mechanism in place to collect near real‐time observations• No link between incoming data, Damage&Loss and flood mapping

• Late delivery for Government briefing• First maps 1 week after the disaster

Analysis limitations

• No data of flood duration (nb days of submergence)• No national system to track flood historical data over time

Limited access to baseline datasets

• No population data at village level• No list of evacuation sites • Restricted data on critical infrastructure: bridges,  health 

facilities, electricity grid, telecom tower, etc.• Possible over‐reporting due to lack of baseline info 

(paddies)

4.GapsandChallenges

Damage and loss analysis is made difficult

5.Arethesemapsuseful?

Relevant at National level• Evidence Base to brief the Government and decision‐makers• Prioritization for resource allocation ‐ UN Agencies and INGO• Area estimation for recovery planning ‐ DDM• Analysis ‐ FAO & MoALI joint crop assessment

Limited use at local level• General Administration Dept village list• No habit to read maps, good local knowledge• Limited bandwidth and printing capacity (no plotter)• Little GIS capacity in the field

Research• Flood modeling (Yangon Technological University)

6.WayforwardHow can we improve?

• Data preparedness• Villages• Infrastructure• Evacuation centres• Vulnerability data• Supporting development of a national coding system to enable interoperability of data from different sources

• Collect rapid field observations• Strengthening collaboration with local actors• Linking with national systems as and when they come into place (such as a national DALA)

• Building local capacity for mapping• QGIS, Google Earth, mobile GPS trainings
