TIGER To MapInfo Translator (TMT©)

Product Specification (PDF File)

First Introduced In 1992, TMT© Now Translates TIGER/Line Shape Files Into TAB, MIF/MID and Shape. TMT© also includes a custom geocoder for working with the roads TMT© builds.

The TIGER To MapInfo Translator (TMT©) from International Computer Works, Inc. (ICW) was the gold standard for translating TIGER/Line® Files to MapInfo TAB format through out the 90’s.  Our next generation TIGER translator, UTT© replaced TMT© with some overlap in time frame and file formats. UTT© is offered as an integrated module of the MapEdit ToolKit©, first introduced in September of 1995. UTT© is also offered as a stand-alone product.

Our TIGER Update Software (TIGERUS©) allows the user to make topologically correct edits to versions of the TIGER/Line® Files from 1995 through the 2006 Second Edition and consists of MapEdit ToolKit© and UTT©.

With the introduction of the TIGER/Line® Shapefiles by the US Bureau of the Census in March of 2008, ICW introduced GeoAuthor® for working with the topology of this new generation of Census digital geography.

While the TIGER/Line® Shapefiles can be translated directly from their native shape format to PBBI/MapInfo TAB files, the results are not suitable for day-to-day desktop mapping applications. Even for use in ESRI products TIGER/Line® Shapefiles need to be converted to a data structure designed for the desktop mapping user. TMT© performs this function.

TMT© also includes a custom GeoCoder that utilizes the left and right side ZIP Codes contained with the address data. This eliminates the need for ZIP Code polygons when geocoding to the roads TMT© builds.

Your geocoding hit rate and accuracy improve with this geocoder when working with the TIGER/Line® Shapefiles or any road network that carries the left and right side ZIP Codes with the ranged address data.

TMT© will translate the TIGER/Line® Shapefiles which can be downloaded to a local computer from the Bureau’s web site. The following is an extract from the Bureau’s website located at http://www.census.gov/geo/www/tiger/:
