DESCRIPTION:Culverted waterways and minor drainage features are physically 
 present but persistently absent in OpenStreetMap — limiting flood and de
 ngue risk analyses alike. This lightning talk documents a YouthMappers-led
  effort to map hidden urban waterways infrastructure and shows how improve
 d completeness changes spatial risk outputs.
