The peak of rain season has arrived, and as usual, Jakarta always got flooded around December until February each year. Information about where flood happen is very important, public need open access to know and understand where the affected areas are. But, of course textual information is not enough. That is why DKI Jakarta Provincial Disaster Agency (Badan Penanggulangan Bencana Daerah (BPBD) Provinsi DKI Jakarta) with assistance from Humanitarian OpenStreetMap Team (HOT), funded by Australia-Indonesia Facility for Disaster Reduction (AIFDR-DFAT Australian Aid ) is creating Jakarta flood map this year.

HOT team + AIFDR staff are creating maps for Jakarta flood response.

Everyone needs to know that all maps that have been published to the public are NOT produced with commercial or paid software. We are using free and open source softwareQGIS 2.0 which is available in for Windows, OSX, and Linux. We are putting this free software under stress to create good maps with fast and efficiently.

During the producing process, there are 3 phases:

  1. Data collection, data processing, and entry data
  2. Symbology setting
  3. Layouting

Tsunami Reduction Training in Padang, West Sumatra

An OpenStreetMap Training was held on 17 to 21 September 2012 at the Hotel Mercure in Padang. The city of Padang is affected by tsunami hazards due to their location on the west coast of Sumatra. OpenStreetMap will be helpful because it will help map critical infrastructure, such as public facilities, land use, roads, etc, that supports the reduction of tsunami risks.

Participants consisted of 22 representatives from BNPB, BPBD, NGOs and students of the University of Andalas. Mr. Yazid Fadhli, the BPBD chairman of West Sumatra, introduced the trainers and speakers. Then, Mr Henry Budianto introduced natural disaster contingency plans in West Sumatra. The first day’s training began with the introduction of OSM and to how to transfer data from a GPS to the computer.

The participants were very enthusiastic about following the material and learning how to use GPS devices in the field and on their computers. Overall, the training seeemd to be quite successful with only a few hiccups, such as tardiness, slow internet connections and lack of computer skills. However, it is useful to evaluate candidates for continuation in the future to be resolved so that the event run smoothly and successfully as desired.

The second day built on the first day’s curriculum with of the event is to collect data from the GPS, update OpenStreetMap data by uploading the changes to the database, create a JOSM preset that contains information about the building in accordance with requirements, provide materials about Walking Papers and sharing group for field trips and provide materials about editing with JOSM. On the second day the 6 small groups to practice the field using GPS and Walking Papers. The groups will be assigned to each location with a Walking Papers and GPS and collect building data.

On the third day before leaving for the field, the participants completed their first written test to recall the material that has been given previously. After doing the one-hour test consisting of 8 questions, the participants were divided back into 6 groups left for their respective locations. During the on-site participants to collect data such as building roads or other information entered into the GPS and Walking Papers. At the time in the field, there are many obstacles especially in populations that we went to collect the data. Characteristics of the population in each location is different there are enthusiastic and there is also disturbed by the activities we do in the field. This was overcome by the approach of each group explain ssedang activities performed in order to avoid misunderstandings later. After collecting the data the group returned to the hotel to continue the event is to enter data from the GPS receivers to JOSM and then make changes to the data according to information obtained after each group advancing to present any information obtained at the time in the field. Furthermore, participants digitised uncharted building according to the location covered by the Tasking Manager.

On the fourth day training event begins with the 2nd test consisting of 5 questions that cover material that had been submitted previously. After conducting the test, the participants went to the field again but with different groups and locations. The groups reduced from 6 to 4 with a more broad area to cover. Each group chose one location then they will collect the same data again the third day. Here the input data facilities at any location they choose various methods of retrieval from the recording using a car or on foot. After collecting the data, the group returned to the hotel to include data that has been obtained into the OpenStreetMap as well as edit the data. We had planned that after the lunch break the participants would return to the field, but because of the weather, training continued in data validation.

On the last day of training we focused on working with the Tasking Manager. We introduced the exported OpenStreetMap data available online: and After that participants did the final test containing 10 questions covering material from the beginning to the end of the meeting and filled out a evaluation of training. Then the ceremony continued with the closing prayer, the distribution of training certificates to the participants and comments from participants on this training. The next, and most important event, was a photo with all participants and trainers. This training has given many many useful knowledge to the participants so that they will use this knowledge for the safety of their territory from the risk of natural disasters.Selengkapnya »Tsunami Reduction Training in Padang, West Sumatra
