coverage, a 1:10 million print of the entire nation, and a series of 1:1 million NTS primary quadran- 
gles are available as continuous tone prints with borders defined by the NTS grid and containing an 
overlay of map information to provide certain name, elevation and geographic detail. 
The Canadian Mapping Industry which consists of some 25 firms continues to be actively involved in 
both domestic and foreign commercial work. Their area of work varies from 1:50 000 National mapping 
to large scale 1:500 city plans. About 8 of these firms have our support capability.
