Data & Database: Data Development
The foundation of all GIS and database systems is data —
without complete and accurate data, the rest of the tools
and methods are useless. Building a functional GIS or other
information technology system means developing the necessary
data through one or more steps of data capture, data conversion,
data entry, data processing, and data validation. With geographic
data, these steps apply to both the spatial and attribute components
of the data.

This example shows a typical data development task: converting
paper maps into GIS format. Steps include scanning the paper maps,
geo-registering the scanned image to known coordinates, converting
the scanned features (streets, streams, buildings, etc) to GIS
elements (points, lines, polygons), and assigning attributes to
the GIS features. The maps here are FEMA
Flood Insurance Rate Maps (FIRMs), being converted to digital format
as part of FEMA's Map Modernization program.
