Why you need to capture GPS data during enumeration
DRS are Worldwide specialists in Census data capture www.drs.co.uk
Reasons for doing this are:
• Geocentric Census – UNSD handbook 1st Draft
• Captured GPS locations can be used as a reference point for future Census activities:
– Buildings and GPS points do not change; designated EA areas and building numbers can
• Information captured with GPS locations has major benefits to other government departments such as:
– Emergency Planning & Humanitarian Response– Flood plain modelling– Planning of social and Educational services– Poverty Analysis– Utility service Planning– Labour force analysis– Marketing analysis– Voting district delineation– Epidemiological analysis– Agriculture Planning
