1. Georeferencing, Geocoding and Address Matching
GEO GIS Practicuum

2. Georeferencing
essential in GIS, since all information must be linked to the Earth’s surface
Georeferencing must be:
Unique, linking information to exactly one location
Shared, so different users understand the meaning of a georeference
Persistent through time, so today’s georeferences are still meaningful tomorrow

3. Geocoding
Geocoding is the conversion of georefencing (spatial information) into digital form.
Geocoding involves capturing the map, and sometimes also capturing the attributes.

5. Geocoding methods for maps
Digitizing
Scanning
Field Data Collection
Vector and Raster
In ArcView Feature Data Source, Image Data Source
Often involves address matching

6. Address Matching
A system for giving a street address a geographic coordinate
Measure a distance along an arc from a fixed point, most often an intersection
