  • Priority: Medium

Overview

The Philippines, due to its geographic location, is regularly subject to various natural disasters. The Northern Cebu Risk Mapping using OpenStreetMap(OSM) is a participatory mapping project of the Philippine Red Cross to improve the base geospatial data coverage of North Cebu for use in disaster response, climate adaptation, risk mitigation, and support other humanitarian initiatives.

Bogo is a sixth class component city in the province of Cebu, Philippines, with a population of 69,911. Located in the northeastern coast of Cebu province, on the principal island of Cebu. It is 101 kilometres from Cebu city.

The Philippine Red Cross continue their humanitarian missions, with partners including the Croix Rouge Francaise, the local government of Bogo, community stakeholders in North Cebu, in collaboration with advocates from the OpenStreetMap Philippines community.


Task Difficulty

Some of the grids are marked as difficult, and are best handled by more experienced mappers.

Imagery

[imagery url available only after accepting the license]

Access to this imagery is limited by the NextView license agreement.

You need to review and acknowledge the agreement.


Mapping

Map the following features:

  • Settlements, tag landuse=residential for groups of houses over five;
  • missing roads
  • tag new buildings with building=yes (if you have local knowledge, be specific, e.g. building=chapel), and delete old building features which no longer appear in current imagery. If the building has a damage tag (e.g. typhoon:damage=yes) from 2013, you may safely remove them.
  • waterways (e.g. waterway=stream)
  • Improve alignment of existing roads, buildings, and waterways when necessary
  • Update landuse polygons (i.e. landuse=farmland)

Please follow the mapping conventions described on the Philippines OSM wiki.
