9. Data Processing

The Chapter highlights the important role of data processing in various stages of a forest inventory. Ideally, data processing (implying quantitative thinking) should begin at the very inception of a forest inventory. Once the inventory problem has been properly structured and worked out, data processing provides support to formulation of inventory design including information on spatial variation pattern, costs and time information to facilitate formu¬lation of cost effective sampling designs using the historic job-files. After finalization of inventory design, attention shifts to writing of field manual. This involves work on classification, coding and recording of data. Crew leaders have to be properly trained in filling forms in the prescribed format and check-crew work. The experience shows that training of crew members in the elementary data processing is always advantageous in the long run. Specially, if data processing steps have been planned in advance, most of the tables and graphics can be printed for direct inclusion in the final report.
