Open source census across coastlines

Does anyone know if relief agencies & other local fieldworkers are expecting to complete some pooled standard questionnaire (if so what's in it and where are all data being mapped?). Questions might include: how many people are alive here? what food and drink needs? what health needs? how many dwelling needs? what infrastructure needs? - I imagine such details would be in phases: immediate survival, minimum sustainable community. Do you think having at least some minimal reporting collation be useful as well as establishing which is the agency or main contact point that overseeing the relief?
