Frequently-anticipated questions:

What does this data set describe?

Title: Forest Land Inventory Arcs (2001): FMU 12
Abstract:
This represents the Forest Land Inventory (FLI) Arcs for Manitoba's Forest Management Unit (FMU) 12 in 2001. The FLI is based on recommendations made by the Manitoba Forest Lands Inventory Technical Advisory Committee (FLITAC) . These specifications were developed specifically for Manitoba and were based on Manitoba's previous forest inventory as well as Alberta's AVI (Alberta Vegetation Inventory) specifications (specifically the draft AVI 2.2).
Supplemental_Information:
The feature class name (LCV_MB_FLI_LAND_FMU12_2001_ARC) components include:
1. ISO 19115 Topic Category Name (LCV for land cover); 2. Location code (MB for Manitoba); 3. Intuitive or descriptive name (FLI_LAND_FMU12 for forest land inventory - land feature class - within forest management unit 12); 4. Date (2001 representing the year of photography); 5. Data type (ARC representing arc or line features)

Why was the data set created?

The FLI is ecologically-based and is designed to accurately represent the location and characteristics of the forest resource. An ecosystem field sampling (volume sampling) program was undertaken in conjunction with the inventory to help characterize the forest resource in terms of total and merchantable timber volumes and to help identify ecological characteristics of the sites.

How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    Type_of_Source_Media: filmstrip
    Source_Scale_Denominator: 15000

  2. How were the data generated, processed, and modified?

    (process 1 of 3)
    The general approach to the forest inventory interpretation was as follows:
    1. familiarization (e.g., review of 1:15,000 and 1:60,000 scale photos and existing digital data, including permanent sample plots (PSPs) and pre-harvest surveys); 2. initial stratification (including revisions to accommodate leaf-off understorey information) and ground truthing plot location selection; 3. ground truthing (air calls and ground plots); 4. transfer of polygon linework to orthophoto; 5. digital loading of polygon boundaries; 6. polygon numbering; 7. detailed interpretation; 8. coding of attributes (in format compatible with digital database); 9. verification and quality control measures.
