Georeferencing, Geocoding and Address Matching GEO 265 - GIS Practicuum

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

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

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

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
