#* Assessed flooded village
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)

Image: MIMU, 2018
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
