CartaLinx

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

Extensive import/export capabilities, including:

• ArcView, ArcInfo, Autodesk World, MapInfo and IDRISI
• Access and xBase database files
• reads US Spatial Data Transfer Standard (SDTS), Digital Line Graph (DLG) vector profile data files, and selected Ordnance Survey (UK) NTF 2.0 formats
• georeferenced raster bitmaps supported in IDRISI, BMP, TIF, DRG, JPG, TGA, CLP, PNG, DCX, PCX and WMF formats
• full geodetic projection and datum transformation -- over 400 reference systems supplied including all US UTM and State Plane zones

• Pentium-based PC (Pentium III or higher recommended) running Windows NT, 2000, XP, 95 or 98/ME
• Minimum display of 800 x 600
• 16 MB RAM (32 or greater is recommended)
