The Uganda Flying Labs (OpenStreetMap Uganda and Drone Nerds Africa) with support from Uganda Red Cross Society Uganda Red Cross Society recently instigated a mission to Bududa district to assess and determine extent of damage in the villages of Bukalasi sub-county after the landslides using GIS and drone technology. The mission was also to document the effects of the landslides in the villages of Bukalasi Sub-county using drone technology and to identify other areas in the region highly prone to mudslides. For this particular mission Uganda Flying Labs provided the expertise in GIS and drone technology and Uganda Red Cross provided emergency guidance and community entry. The two organisations worked collaboratively to enable the mission to be carried out successfully.
Aftermath of the Bududa Landslides
In conclusion the mission to assess the affected areas of Bududa District was a success. Both the affected and prone areas were successfully mapped. Pictures of the affected areas were captured. The team of experts demonstrated their willingness to respond voluntarily and quickly to a humanitarian crisis, and we also received offers of help from the drone community worldwide.

The data captured will be processed, analyzed and manipulated to produce a map showing the hot and cool zones of landslide prone areas of Bududa district. This information will provide stakeholders with a a better perspective of the nature and magnitude of impact, and support informed decisions to resolve the needs of the community. The orthophoto created will be uploaded to OpenAerialMap and used to set up a remote mapping tasks on the HOT tasking manager for the global OSM community to map all the features affected by the mudslide.
