Development Seed data team has been supporting the HOT community for a long time collaborating in many mapping projects in response to disasters, health, transportation.

The main objective on the participation in these disaster projects in these cities is to mitigate and reduce the impacts of natural disasters, thus helping the population to save lives and reduce the victims of events.

In the last months, Development Seed data team have been working in Ebola 2018 campaign, in this campaign 58 projects were created on tasking manager that have been developing since May, the Development Seed data team supported a project in the Congo, other projects where our team helped were in the project of the eruption of a volcano in Guatemala, earthquake in the city of Takatsuki in Japan, and also in floods in the cities of Kurashiki and Sojya - Japan.

More detail about each project and our support in each one can be seen below:

- Ebola virus disease in Democratic Republic of the Congo

### - Project 2018 Ebola #49, Lac Tumba south 2

On 2018 May 8th, the Ministry of Health has announced the 9th Ebola outbreak in the Democratic Republic of the Congo. This task was aims to map the buildings in the villages south of Lac Tumba, in Equateur province.

The purpose of this mapping is to track all buildings that exist in the area to be able to visualize the population that exists in the area, which could be affected by Ebola disease if the spread of the disease is not prevented.

Since May 8, 2018, 21 suspected cases of Ebola (including 17 deaths) have been reported in DRC (Democratic Republic of the Congo) in Equateur province, in the Bikoro health zone. So far, 2 cases are confirmed. The full extent of the outbreak is still unclear. The doctors are already working in the field.

This OpenStreetMap crisis mapping project is set up to help efficiently respond to the outbreak.

This is how the OpenStreetMap mapping community came to work in order to help with the mapping by creating tasks throughout the area where the disease is spreading, more than 40 tasks were created throughout the area, in these tasks the activities were to map the use of residential land, roads, rivers and buildings, this task is done in two phases, the first face is to locate the populated areas and then add the buildings detected by the satellite images, the satellite images used were Bing and ESRI .

The Developmentseed team came together to help map the area for two weeks, in which approximately 10,000 objects were added.

Below we can see the map where the tasks were created by the community.

Currently, many roads in the US are misaligned and out of date according to the satellite imagery, but also exists a bunch of missing roads that should be added and named according to the information provided by the Delta Tiger layer, which is updated until 2015. There were detected 126,981 errors in the cities of EE.UU, so to handle them we use OpenStreetMap Java editor (JOSM), which has some additional plugins such as tofix to solve errors detected in the tiger delta task.

We should install the JOSM plugin by going to the preferences icon, then to the plugin option icon where we search for tofix and finally, check the box and press OK.
