Humanitarian OpenStreetMap Team Indonesia Maps Infrastructure Data for Disaster Management in Surabaya
Early this year, major parts of Surabaya were inundated by floods. Occasional event such as this may paralyze economic activities and put its citizens’ well-being in danger, especially in a densely populated urban city, such as Surabaya. In order to minimize the impact, concerted efforts are undertaken. This includes collectively updating the city’s base map data, which is crucial to support the creation of an accurate contingency plan in the unfortunate case of disaster.
A tool to improve the overall risk assessment, early-warning and disaster-management decision making, InAWARE, developed by the Pacific Disaster Centre (PDC), alongside with the National Agency for Disaster Management (BNPB), is being enhanced by data from Peta Bencana–Massachusetts Institute of Technology (MIT) and the Humanitarian OpenStreetMap Team (HOT).
Tasked with mapping Surabaya’s infrastructure data, HOT commenced with training for the recruited project Data Entry (DE) and Quality Assurance (QA) specialists at the new office in Surabaya. A total of 16 DE and 4 QA specialists were trained in a three-day program, covering the use of the Tasking Manager, Java OpenStreetMap and OpenMapKit. The standardization of OSM objects and attributes, the process of collecting and validating data remotely and on the ground, resolving imagery offset and conflicts were just some of the topics of focus.
The city consists of 31 sub-districts (kecamatan), each containing a varying number of villages (kelurahan) within their boundaries, with 160 in total. The mapping approach for the time in Surabaya will be carried out by separating the city into two sections, where each team consisting of 8 DE and 2 QA will be assigned 15-16 sub-districts. The map below shows that division between the North (15 kecamatan/sub-districts and 80 kelurahan/villages) and the South of Surabaya (16 kecamatan/sub-districts and 80 kelurahan/villages).
For this month, our team is focusing on digitizing building footprints, road networks and waterways in the following 7 subdistricts, prior to a mapathon with Sepuluh Nopember Institute of Technology (ITS) in early November.
1. Kecamatan Bulak [http://tasks.hotosm.org/project/2063]
2. Kecamatan Genteng [http://tasks.hotosm.org/project/2066]
3. Kecamatan Gubeng [http://tasks.hotosm.org/project/2067]
4. Kecamatan Mulyorejo [http://tasks.hotosm.org/project/2079]
5. Kecamatan Sukolilo [http://tasks.hotosm.org/project/2078]
6. Kecamatan Tambaksari [http://tasks.hotosm.org/project/2074]
7. Kecamatan Tegalsari [http://tasks.hotosm.org/project/2068]
Over 350,652 edits and 59,133 buildings were added during the training through the listed Tasking Manager projects. The tool is being used to divide up the mapping by kecamatan and to strategically organise the data, it also allows individuals from around the globe to participate in mapping for the project. Participation of our community members, especially those living locally within the vicinity of the listed villages can assist the success of this project, which is crucial for improving Surabaya’s real-time hazard monitoring and early warning system.
Listed as part of the Missing Maps project, the data collected from this process will be free and open, and be made available to the public to better respond to crises as well as to innovate for other economic development purposes. We invite our community members to contribute towards the InAWARE project and support the disaster management of the city of Surabaya, Indonesia, by remotely mapping through the provided Tasking Manager links above. First-time mappers are welcome to learn how to contribute here
