TiVec is a data processing program that enables the user to process Tiger Line files from the Census Bureau and convert them to MID/MIF or SHP/DBF files for use with major GIS and mapping suites. At the same time, it allows the user to select Lat/Long or Lambert projections, separate Tiger feature characteristics, smooth out data for compactness, create composite polygon files, and much more. It comes with a built-in MID/MIF and Shape file viewer, with full zooming and panning capabilities, that allows the user to immediately do a visual check for data coverage, look at multiple layers, etc.

It supports both TGR and ZIP source data archives, and has been updated to include new attributes introduced in the 2000 census release.
