OpenStreetMap Training at Institut Teknologi Bandung, Bandung

Fasting month did not prevent people to be productive. This was proven on July 25th, 2013 when Humanitarian OpenStreetMap Team (HOT) Indonesia visit Insitut Teknologi Bandung (ITB) and have a chance to share knowledge and experiences on OpenStreetMap (OSM) to several Master and PhD students from Civil Engineering and Geology department. The main focus is on the OSM ability to collect building data. The event also attended by Kristy van Putten and Charlotte Morgan from Australia Indonesia Facility for Disaster Reduction (AIFDR) and Hyeuk Ryu from Geoscience Australia which try to apply Earthquake Risk Model (EQRM) to estimate earthquake impact on building.

The training was located in Pusat Penelitian Antar Universitas (PPAU) ITB and attended by five participants. The event committe explain that this training was intended to limited number of participants to enable intensive interaction and discussion between trainer and participant so that a more comprehensive understanding could be attained.

In this one day training, HOT taught OSM basic to introduce the participants what is OSM, what kind of exposure data can be collected through OSM, and how to collect those exposure data in the field. Below are the rundown of the training session.

On the first session of the training, HOT explained OSM basics and how to make account in OSM. The participants follow the steps enthusiastically and some of them even already had OSM account. The next session is Java OpenStreetMap (JOSM) installation and the basic technique to draw and edit in JOSM. Since the participants background are from engineering and already familiar to use similar software, there are no hurdles to draw in JOSM. The main difference in JOSM is that they need to add preset to each objects that they created. In the next session, various drawing tips in JOSM are taught so that a good quality OSM data can be achieved.

On the outdoor session, participants were taught how to use GPS and Field Papers. Participants were grouped into two, where each group carried a GPS and Field Papers with satellite imagery background and OSM data as comparison. The target regions to be mapped are ITB campus complex which surround PPAU building. They mapped buildings in the area and add building data on it. After the field practice, each group input the data from GPS and Field Papers into OSM using JOSM.

On the last session, participants were taught private datastore, that is a feature from OSM which enables us to store private/secret data, unaccessible from public. This feature would be really useful when the object being mapped contain sensitive data, such as social mapping or building condition. Last but not least, participants practice how to obtain OSM data using Hot export and geofabrik. The result are shapefile (.shp) data which will be useful in spatial data processing in a project.

HOT would like to convey its appreciation to event committees and participants of the training, who keep their enthusiasm in the middle of fasting month. It is hoped that the shared knowledge will be useful and applicable.
