Is a 175000 scale map a large scaled map?
The terms "small scale" and "large scale" are relative terms.
Compared to a street map (typically 1:30000 or less) it is a large
scale. Compared to a world map (1:10,000,000 or higher), it would
be smaller.
But because a 1:175000 does not show much detail (1 cm = 1.75
km), it would usually be considered a large scale map. It could be
used for a metropolitan area highway map.
