This is spatial data depicting the cut block boundaries and year of harvest for crown lands within British Columbia. It is created from the provincial Forest Cover, from The RESULTS Reporting system, from Forest Tenures applications and from satellite imagery using change detection processes. It represents the gross opening area when derived from forest cover, RESULTS or Forest Tenure data and does not exclude non harvested 'reserved' areas. Satellite image change detection represents the area harvested each year and may not be the entire cutblock area and will not include non harvested 'reserve' areas.

Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

To help analyse the footprint of harvesting activities in BC.

Data Quality

This data is reasonably accurate for the last 10 years , and usable for the last 20 years, It is unreliable for anything older than this.

Object Description

Object Name: WHSE_FOREST_VEGETATION.VEG_CONSOLIDATED_CUT_BLOCKS_SP

Short Name: CNS_CUT_BL

Column Name Short Name Data Type Data Precision Comments
VEG_CONSOLIDATED_CUT_BLOCK_ID CUTBLOCKID NUMBER 10 VEG_CONSOLIDATED_CUT_BLOCK_ID is a system generated unique identification number.
OPENING_ID OPENINGID NUMBER 10 OPENING_ID is a system generated value assigned by RESULTS to uniquely identify the opening.
HARVEST_YEAR HARVESTYR NUMBER 4 HARVEST_YEAR is the year of harvest, derived from the disturbance start date of the data source or from the year the disturbance was detected using Landsat change detection.
DISTURBANCE_START_DATE DSTRBSTDT DATE 7 DISTURBANCE_START_DATE is derived from the data source. RESULTS describes it as; derived from the first reported disturbance activity reporting. This date is used to calculate the silviculture obligation milestones.
DISTURBANCE_END_DATE DSTRBEDDT DATE 7 DISTURBANCE_END_DATE is derived from the data source. RESULTS describes it as; derived from the last disturbance activity reporting record based on the disturbance activity's completion date.
DATA_SOURCE DATASOURCE VARCHAR2 20 DATA_SOURCE is the highest priority source of data for the disturbance polygon. The order of priority used is VRI, RESULTS, FTEN and then Landsat Change Detection.
AREA_HA AREAHA NUMBER 10 AREA_HA is the system calculated polygon area in Hectares, calculated to 2 decimal places.
FEATURE_AREA_SQM FTAREASQM NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M FTLENGTHM NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
SE_ANNO_CAD_DATA S_NN_CD_DT BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
