On February 1-2 and 9-11, 2016, HOT, in cooperation with ADRA (Adventist Development and Relief Agency), did a mapping activity in Karawang. The four villages that were chosen by ADRA are located in Karawang’s coastal area which have a high potential disaster threats. The villages are Ciparagejaya Village, Pasirjaya Village, Cikuntul Village, and Muara Village. These four villages sent some of their village officials to map their own village.
This mapping activity started with a data collection training using OSM on February 1-2, 2016 in Pasirjaya Village’s office. On the first training, the participants were taught on how to map their area with OSM. Before the training started, the participants were asked to discuss what kinds of objects that they want to put on their village map output. Most of them wanted to map the land uses (farming and fishponds), road network, buildings, farm roads, river, and irrigation channels. After the discussion ended, the participants were introduced to GIS and OSM concepts as a general view on what they were going to learn during the training. The first thing they did after learning about the concept were signing up to the OpenStreetMap website. Each village has its own account, the activity then continued on how to map using JOSM and some tips on digitation technique. Later on the day, the participants also learned how to make field papers and did a practice session on using GPS.
On the second day the activity started a bit late because of bad weather. It was raining in the morning caused some participants to arrive late. At 10 AM the rain began to reduce, the activity started with dividing participants into 3 different field survey simulation groups. In this simulation activity, participants brought field papers, survey forms, and a GPS unit then tried to collect public facilities data such as kiosks, mosques, health clinics, and schools. Some participants also did some interviews with local communities to collect data about sanitation facility available in their homes and their behaviour in disposing household waste. This field survey simulation was done at 12 PM and continued with inputting the data from GPS and survey form into JOSM then digitized and uploaded them into OSM server. At the end of this activity, the participants were given a debriefing session about their plan on mapping their own village for 6 days after the training ended. This 6 days survey purpose was to collect a complete data and map their village, mapping the public facilities, health facilities, and household, using the same tools that they’ve used during the field survey simulation.
Then the activity for these 4 villages continued on February 9 – 11, 2016 at Cikuntul Village office. This follow up activity generally intended to input the data that they’ve collected in their own villages and process the data to produce a print ready map using QGIS. The participants were asked to input the survey data right away then upload it into OSM server. Unfortunately, there was one village that couldn’t join the training for 2 days due to their internal event. The villages that attended the survey data input were Ciparagejaya Village, Muara Village, and Cikuntul Village. Each of these villages was assisted by one HOT facilitator. Each facilitator also assisted the village officials to fix their village boundaries and added some hamlets and sub villages boundaries as well. Out of 3 villages, only Cikuntul village that could managed to collect 223 household data while the other 2 villages couldn’t collect that many. The data input activity was ended at 5 PM. At the end of the day, all public facilities for 3 villages were successfully inputted into OSM, while some of the administrative boundaries were being digitized by facilitators.
On the fourth day we started with QGIS application installation in every participant’s laptop. This day’s training was focusing on how the participant can obtain the data that they’ve inputted into OSM in order to be processed and symbolized and created into a map for each village. To get the OSM data, they used a QGIS plugin called QuickOSM for each village. After getting the data, they were taught on how to see the data attributes from each village and how to perform data filtering based on each village’s needs. After taking a lunch break, they continue choosing colours and shapes (symbology) froe their data depends on the land uses, road networks, water network, and building types. They also learned to convert polygon data into point data. This was needed because the public facilities that they’ve inputted were mostly in the polygon shape, to give a specific symbol they need to convert the data into points first.
Last day of the training was started by continuing the symbology session that was delayed from the previous day. After that, they created their own map using Map Composer in QGIS. Before they started creating the maps, the facilitators created a competition where participants with the most beautiful map design could win a gift from HOT. Cikuntul Village was the winner of the map competition due to the colours and beautiful composition that they use in the map so it was easier for people to understand their map. After the map creation session ended, they also learned how to use InaSAFE to see the impact of a disaster in their own areas. They were taught on how to use their own exposure data from their villages and a hazard data they’ve got from the depiction of impacted area in the field papers.
After the whole activities ended, the next step that will be delivered by ADRA is to motivate and support each villages to continue mapping their area and also to collect household data as much as they can, in the hope that the OSM data in their village becoming richer.
