Last February 9-11, the Philippine Red Cross (PRC) and the Croix-Rouge Francaise hosted a 3-day OpenStreetMap workshop in Bogo, Cebu, as part of their Northern Cebu Risk Mapping project. This participatory project aims to improve the base geogspatial data coverage of Northern Cebu for use in disaster response, climate adaptation, risk mitigation, and support other humanitarian initiatives. It was attended by local government staff from Bantayan, Daanbatayan Island, Bogo, and local PRC volunteers.

• Day 1: Introduction and Basic Editing on OSM

Day 1 consisted of an introduction to the PRC project and a general overview of OSM and OSM-Philippines. A presentation of the objectives of the data collection and an introduction to the mapping components were also given. Before the discussion of the OSM website, we had an activity wherein participants were asked to draw their vicinity map and explain their maps afterwards.

One map caught our attention, though… it’s 3D!

• Day 2: Field Data Collection Tools and Tasking Manager

On the second day of the workshop, participants were taught how to use some tools for field data collection like Field Papers, GPS handheld devices and OsmAnd for smart phones.

Luckily, we were given an access to Digital Globe’s WorldView-2 satellite images taken on February 15, 2015. These images were humbly provided by the MapGive Project, through Celina Agaton’s initiative Map the Philippines. The image is orthorectified for terrain corrected geographic precision. Furthermore, the image has been contrast stretched using a custom stretch and processed into a Tiled Map Service (TMS) for performance. It allows the participants to use the imagery and digitize features on the map.

Tasking Manager:

We set up a Tasking Manager for this workshop. You may access the task here.

Statistics of the Bogo Tasking Manager; As of February 19, 18% of the mapping tasks was done. Long way to go!

• Day 3: Fieldwork and Quality Editing

The last day of the training involved an actual field data collection in Barangay Libertad and data processing from the field.

Here is the recorded GPS track and waypoints of #TeamFeye:

… and some group photos ;) :

Before we end the workshop, we asked the participants to divide themselves according to their LGU groups and to present their plans of future data collection activities using OSM.

We would like to thank Mikko Tamura of Philippine Red Cross and Lucas Schott of Croix-Rouge Francaise for making this happen. We hope to see more edits from the participants in Northern Cebu.

– Thank you from OSM-Ph trainers (@rally, @GOwin, @feyeandal)!
