Normally strategic, though occasionally operational (e.g. urban search and rescue). Largely dependent on the scale and level of aggregation within the data.Basemap, baseline or situational?
Situational.When might it be produced?
Operational 3W maps might be required during user search and rescue phases. Strategic 3W maps will be required as the clusters and overall coordination mechanisms ramp up. 3W mapping is usually intended as a tool to help decision-makers track and allocate resources, filling gaps and avoiding over-resourcing. It's an essential planning tool in most emergencies.
Organisations - Governments (National or Local), UN, Clusters, NGOs, Donors and others;
Roles - Programme Managers and fundersInfluence on humanitarian decisions
The most commonly invoked rationale for 3W mapping is to identify gaps and overlaps in the relief effort and provoke the reallocation of aid as appropriate. A much more detailed discussion of the purpose of 3W mapping (from OCHA’s perspective) can be found here: OCHA 3W - Its Purpose Target Audience Scope and Products - V1 - May 2013. Note that cross-cluster 3W data is normally limited to recording ‘operational presence’ of agencies but is NOT expected to serve as a tool for monitoring volumes of assistance delivered.

Large 3W datasets can be mapped using Data Driven Pages (ESRI) or QGIS Atlas.
