Arc

An ordered string of vertices (x, y coordinate pairs) that begin at one location and end at another. Connecting the arc’s vertices creates a line. The vertices at each endpoint of an arc called nodes.

      -

Axis

A reference line in a coordinate system

Automated Mapping

The use of computer graphics technology to produce maps. May include specialized CAD technology for digitizing and editing map features, and DBMS technology to produce thematic maps.

       -  

Automated Conversion

The process of converting maps and drawings into a digital format while reducing or eliminating operator intervention. Scanning is one form of automated conversion. Heads-up digitizing via tracing a raster image displayed on a computer screen is another form.
