DEPARTMENT OF LANDS AND FORESTS FOR 1947 145 



DIMSIOX OF SL'RXEYS AXD EXGIXEERIXG 



The furtlicr development of the natural resources increased the activities 

 of the Department as a whole and this was reflected in the work undertaken by 

 this Division. In so far as qualified personnel were available, efforts were made to 

 cope with the backlog of field and office work that had accumulated as the 

 result of personnel shortages during the past jears. 



In the Forest Inventory Project as undertaken b\- the Department over a 

 five >ear plan, the Division of Surveys and Engineering is responsible for covering 

 18.000 square miles b\' vertical photography and the preparation of planimetric 

 maps to a scale of four inches to one mile. An area of 5,054 square miles has 

 been photographed during the past fiscal year. Ground control surveys were 

 undertaken in the Districts of ("ochranc and Thunder Ba>' to pro\-ide accurate 

 and sufficient ground control points in areas previoush' unsur\-e\ed. 



The preservation of our surve\" records, representing land surveys carried 

 out o\-er the length and breadth of the Province over the past 150 >ears, is most 

 important. The work of microfilming the field books was commenced this \"ear 

 and the films stored in fireproof containers. 



The following aerial and ground surveys were undertaken during the fiscal 

 }ear ending March 31st, 1947:
