Tiger Line data
File type: GIS, GPS navigation and map file
Files with tgr file extension might be found as older Tiger Line files. Some sort of GIS format.
File type category:
GIS, GPS navigation and map file
Date updated: December 12, 2017
Record marked as obsolete and not updated for a long time.
The tgr file extension is mainly related to Tiger Line products from U.S. Census Bureau. TIGER is short for Topologically Integrated Geographic Encoding and Referencing.
Seems like older format replaced by newer standards.
