Community Mapping For A Resilient Bamako

The Community Mapping for a Resilient Bamako project focuses on specific challenges facing Bamako city, Mali, such as rapid urban growth, increased prevalence and risk of flooding and associated challenges with solid waste disposal and collection, access to clean water and sanitation, and access to key services such as public transport, health and education. Focus areas for this project will be determined by a combination of interviews with stakeholders, Focus Group Discussions, and in coordination with the World Bank Task team.

In this project HOT builds on proven approaches for community-based flood mapping and monitoring developed under the World Bank Ramani Huria (Tanzania) program, Open Cities Africa programs, as well as the GFDRR/DfID Challenge Fund global open exposure data project. HOT, the OpenStreetMap Mali community (OSM Mali) and the Croix-Rouge Malienne (CRM) have teamed up for all phases of the project and will build upon relationships with multiple government agencies and civil society stakeholders in Bamako.

Data collected as part of Community Mapping for a Resilient Bamako project conforms to a model. The Data Model specifies what types of attributes are collected, what answers are possible, and the style in which they are displayed on the OpenStreetMap website's rendering and the Community Mapping for a Resilient Bamako's own atlases (essentially QGIS styles). The model consists of three basic layers:

1. Items that appear in the OpenStreetMap standard rendering, and therefore conform to an essentially universal schema - they should look, by and large, identical in the street map in any country. Examples include the usual classifications of roads and buildings; the usual elements of the street map.
2. Items that conform to OpenStreetMap standard tagging, but don't necessarily render on the standard map style. These should nevertheless be invariant across multiple countries and contexts. Examples include drainage, which does not appear in detail as part of the usual street map style, but is nevertheless universal and should be tagged consistently regardless of the local context.
3. Items that are specific to the local context, which do not (fully) appear in the OpenStreetMap standard rendering and are not particularly universal, but which are useful to support the specific goals of the local project and community. Examples include local health-care infrastructure which is organized in a context-specific fashion by the national Ministry of Health, or administrative divisions that don't easily fit into an Adm1, Adm2, Adm3 schema.
