Frequently anticipated questions:


What does this data set describe?

Title:
Forest Land Inventory (2011 & 2013): Nelson River Forest Section
Abstract:
This represents version 3 of the Forest Land Inventory (FLI) polygons for Manitoba's Forest Management Units (FMUs) 83, 84, 85, 87 in 2011 and 2013. Collectively, these FMUs form the Nelson River Forest Section. Version 3 of the Nelson River FLI includes additional updates to some records for the STRATA, DENAGG (density class aggregate) and SIC (site index class) fields.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).Nelson River Forest Section (2011 & 2013) FLI has z-values and can be viewed in 3D in ESRI's ArcScene, or DA/TEM's Summit Evolution.
Supplemental_Information:
This dataset represents version 3 of the Nelson River FLI and includes updates to some records for the STRATA, DENAGG (density class aggregate) and SIC (site index class) fields.

Why was the data set created?

This represents version 3 of the Forest Land Inventory (FLI) for the Nelson River Forest Section (2011 & 2013) of Manitoba with enhanced attributes such as STRATA, SPP_SUM, etc. calculated. Version 3 includes additional updates to some records for the STRATA, DENAGG (density class aggregate) and SIC (site index class) fields.
The FLI is ecologically-based and is designed to accurately represent the location and characteristics of the forest resource.


How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    Type_of_Source_Media: None
    Source_Contribution:
    Interpreted Forest Lands Inventory (FLI) polygons from 2011 and 2013 aerial photography for Manitoba's Nelson River Forest Section

  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 of the general area; 2. ground truthing (air calls and ground plots); 3. delineation in Summit Evolution based on aerial photography; 4. interpretation of delineated polygons; 5. coding of attributes (in format compatible with digital database); 6. verification and quality control measures.

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


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: Polygons must not overlap; Polygons must not have gaps.


How can someone get a copy of the data set?

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