What does this data set describe?

Title: Forest Land Inventory Polygons (2001): FMU 12
Abstract:
This represents the Forest Land Inventory (FLI) polygons 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:
Although present, the following fields were not populated with data for all of FMU 12: SACOV1, SACLASS1, SACOV2, SACLASS2, COVARR, CANPAT, SPH, LANDMOD, LMODNO, TOPO, SLOPEPOS, SLPER, ASP, US2CANPAT to US5CANPAT, US2SPH to US5SPH and US2NNF_ANTH to US5NNF_ANTH. If data does exist for these fields within some records, these represent attribute values captured during the interpretation of FMU 14.
The feature class name (LCV_MB_FLI_LAND_FMU12_2001_PY) 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/Geometry type (PY for polygon)

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 1)
    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.

  3. What similar or related data should the user be aware of?

    Manitoba Conservation, Forestry Branch, November, 2009, Forest Land Inventory Polygons (2001): FMU 12.


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

  5. How consistent are the relationships among the observations, including topology?

    Topology Rules Applied:
    1. ENV_MB_FLI_LAND_FMU12_2001 must not overlap; 2. ENV_MB_FLI_LAND_FMU12_2001 must not have gaps; 3. ENV_MB_FLI_LAND_FMU12_2001 boundary must be covered by ENV_MB_FLI_LAND_FMU12_2001_ARC


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
