To celebrate Osmgeoweek2019 and Birthday of Dhaka College #DC179, we(Youth Mappers Dhaka College) organize a mapathon “Map for Humanity “ on 22 November 2019. We along with new members work on an vulnerable area where we try to give support of that region and different NGO’s so that they can take steps on that vulnerable area.In and around Bossangoa in the Central African Republic, MSF teams provide consultations in hospitals and health centres, and support a network of community health workers. A better map of the region will help the teams to understand the exact situation in the area and will allow them to make rough population estimations.So,we updated the maps to help them with drawing building, highways, waterways and so on. Some new students sign registration and participate in this mapathon. First we arrange a training session where we discuss about OSM,Youth Mappers,and Map related other questions. Then we gave them handson training,how can we make map, how can we contribute on OSM, how can we draw a building with proper shape?How can we draw a highway or a waterway or a waterbodies? After discussion and answering remote draw related questions, we along with our new members contribute on Hotosm Tasking Manager -Task No.#7033 - Missing Maps: Mapping buildings in Bossangoa (city) - Ouham , Central African Republic At last session we discuss how can we progress and what may be our future plans.We also make plan organizing another mapathon for celebrating our Victory Day 16th December. In the end,we all take part in tea party.
