We conducted another Beginning OpenStreetMap Workshop. This time in Lembang, Kab. Bandung, West Java, on 24-28 September 2012, precisely at the Grand Hotel Lembang. The participants appreciated this workshop just as much as the previous participants in the Padung workshop last week.
The Bandung participants represented 15 BPBD Provincial & Districts, Public Health Service, LIPI, IOM, Red Cross, and the PRB Forum Wanadri in West Java Province.
Wulan asked questions to one of the participants, Mr. Hersuparyoto, a representative of BPBD West Java Province. More specifically, he works in the Operations Control Center of BPBD West Java. He was one of the few participants who had OSM experience from a workshop before. However, this was the first time he learned how to edit in JOSM. Previously he had only used the online editors, namely Potlach. Pak was using OSM to map the Bogor region. He was also using ArcGIS and MapInfo to aid in the mapping process.
Although you probably cannot tell by his humor and relaxed demeanor, he often participates directly in the field when disasters occur. Sometimes even as the coordinator of the response team. He currently helps with Tangkuban Parahu activity monitoring.
He said, the most common threats in West Java are floods, landslides and earthquakes.
He admitted OSM is very convenient and easy to use for creating maps, especially for beginners. “OSM is easier to use because satellite images are used as our base to make maps readily available and free, the one with the image of Bing Sat. When using Map Info you have no satellite image data”, said Mr Eko, his nickname. However, he regretted that the OSM could not be used for disaster vulnerability mapping. Because of what appears on the OSM map illustration only what is on the surface. For the future he will continue to use the OSM mapping data mapping and hope that there are more complete, because everyone can contribute here.
The rest of the workshop ran smoothly. On the first day, participants were introduced to OpenStreetMap (OSM), told how to register and what the basic stages of making a map with OSM were. Most of the participants were people who work directly in the field, so this workshop provided them with the skills to begin using maps in their work. Besides Mr. Eko, none of the participants had previous OSM experience.
After the introduction of the OSM, the participants were introduced to Java OpenStreetMap, the offline editor. Some of the participants had difficulties with JOSM, but they keep their spirits up. Us trainers were ready to provide solutions and answers when difficulties arose.
Activities in this workshop were not only carried out in the room, but also in the field. Field surveys were conducted using GPS and Walking Papers to obtain accurate and current data. Participants were divided into six groups and sent to areas around the District of Lembang to map buildings and existing public facilities. Remarkably, the participants still keep their spirits high even when they had to walk under the harsh sun and up and down steep paths.
On the fourth day of training, we surveyed one of the high risk volcano areas, Tangkuban Parahu, near the village of Cikole. Mount Tangkuban Parahu had just re-opened on 22 September 2012 after being closed due to volcanic activity, which had increased on August 23, 2012. Tangkuban Parahu is an active volcano that is closely monitored.
Disaster vulnerability maps are necessary tools for decision makers in disaster management. To make these maps requires important spatial data. The more details that these maps contain, the more detail and precise the response can be.
