TPQ files are map files associated with TOPO! software from National Geographic Maps. They contain map imagery or related data used to display topographic maps in the application.
The files are part of the software's map resources rather than general-purpose image files. The TOPO! State and Weekend Explorer programs use them together with the other data required for their digital map collections.
TOPO! State and Weekend Explorer was released for multiple desktop platforms. The format is a legacy, proprietary format, so it is primarily useful with compatible TOPO! software rather than current general-purpose mapping applications.
Open a .tpq file with a compatible TOPO! program, such as TOPO! State and Weekend Explorer. The file may need to remain with the other files from the same map collection for the software to load it correctly.
Because TPQ is a proprietary map format, it is not normally opened directly by standard image viewers or GIS applications.
There is no known general-purpose converter for the tpq file extension. The file is intended to remain in the proprietary format used by TOPO! software.
