The coastline of the Turbo municipality (Urabá, Antioquia, Colombia) is highly dynamic due to both coastal erosion and sedimentation, particularly along the Eastern coast of the Urabá Gulf. As consequence, multiple coastlines have been mapped in OSM. In addition, many fishing villages are not found in the OSM.

I would like to lead a long-term mapping program to update the coastline and other features such as human settlements. I plan to promote a mapping marathon, anyone interested in supporting this effort?

Please check two popular papers I wrote a while ago using high resolution aerial imagery to highlight the issues on sustainability in this coastal area:

The aerial photo mosaic (ortophotomosaic) would be available soon to the public:
