Asset Mapping & Gift Inventories
James, sorry so long in responding.
I would suggest that asset mapping must be done by community members themselves, so it is shared through personal connections. From my perspective asset mapping is a process of Identifying people's gifts and passions, asking them to share their gifts with their neighbors based on their passions and connecting people with the same passions to act collectively.
