CartaLinx is used to create coverages, consisting of the spatial definitions of features in vector format, and associated attribute values files. These data are then typically exported to a GIS.

CartaLinx accepts data from a variety of sources, including the use of a mouse as a coordinate input device, CoGo bearing and distance measurements, and any GPS device capable of outputting NMEA1 format data records over an RS-232C cable connection. Over 300 digitizing tablets are also supported through the Virtual Tablet Interface™, sold separately.

CartaLinx uses a full topological editor/digitizing system with capabilities for:

automatically building vector topology (connectivity between nodes, arcs and polygons)
automated generation of polygons and assignment of ID’s by means of polygon locators (label points)
insertion, deletion or movement of nodes, arcs or arc vertices
real-time projection/datum transformation of digitizer and GPS input data to meet mapping reference system specifications
feature filtering and extraction to new spatial databases based on feature attributes (filter) or location (clip)

CartaLinx also has significant analytical and mapping capabilities, including:

relational database query support, producing custom maps based on specific feature attributes
support for mathematical modeling, creating new derivative data fields using mathematical operations on existing fields
interactive feature inquiry, instantly displaying attribute data for any feature by simply clicking on that feature
real-time route monitoring using GPS with an image backdrop
text placement with scale-sensitive sizing
