Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the portions of land in four condensed maps which illustrate the kind of forest maps that were being prepared from air photographs with a minimum of groundwork by the Forestry Branch of the Department of Northern Affairs and National Resources in the 1950s. Such maps not

Radar-derived standwise forest inventory
IEEE Transactions on Geoscience and Remote Sensing, 1997The application of remote sensing methods in the estimation of forest stand characteristics, especially biomass and stem volume, has been intensively investigated during the last few years. The new methods, however, have not been accurate enough for operational standwise inventory with a required accuracy typically of 15% for main stand characteristics

Inventory of Forest Plantations
2013We review the research related to the application of inventory techniques utilizing airborne laser scanning (ALS) in intensively managed forest plantations. The single tree detection and area based methods originally developed in more complex forest types were found to be no less effective in plantation forests for the estimation of important stand ...

Metrication and Forest Inventory
Journal of Forestry, 1973Abstract A multistage forest inventory system with the dual capability of accepting either U.S. or metric inputs and outputting summarized results in either type of units is described. Interconversion of angle-gauge factors from U.S. to metric is facilitated by a compact table.

A Partial Ontology for Forest Inventory and Mensuration
16th International Workshop on Database and Expert Systems Applications (DEXA'05), 2006Keywords, restricted vocabularies (RVs), thesauri, and catalogues are introduced leading up to discussion of the need for full ontologies to describe the full logical and relational structure of e-information-objects (e-IOs) (data or docs). A re-ordered and (re-) structured NEFIS RV for forest inventory and mensuration (FIM) is (re-) presented, leading
