LiDAR Based Harvest Planning

Customer:
Location: Southern Interior of BC near Adams Lake
Timeframe: 2014

Silvatech has been producing detailed Total Chance Plans in BC for over 20 years using 3D stereo-plotters and digital imagery. We have been using LiDAR technology for the past 15 years. Operational planning has just gotten better with greater detail and consistency as LiDAR technology has advanced and costs have plummeted.

At Silvatech, we produce operational plans depicting block boundaries, access routes, road grades, slope themes, harvest types, deflection lines, landings, skid and yarding trails, leave areas, visuals etc. We can also enhance existing inventories making them more suited to operational plannig

Water/Wetlands Inventory

Location: NE Alberta, Canada
Timeframe: 1 month

Automated Water Feature Delineation from Lidar Data

Information on the location and extent of water and wetland features is essential for many applications, including various aspects of environmental planning and management. Accurate mapping of water feature information is often costly and time consuming as it is typically labour intensive.

The sample to the right exemplifies a project involving an innovative water delineation procedure developed by the Silvatech based on lidar data collected with the FUGRO FLI-MAP system, over-laid on orthophotography. This approach features a very short turnaround time.

Silvatech has also developed procedures to take advantage of the unique aspects of multi-spectral imagery and lidar data, enabling direct detailed delineation of water features present on the landscape at the time of data collection. The result is a timely, accurate, low cost solution for extracting water features.

Forest Harvest Planning

Customer: British Columbia Timber Sales (BCTS)
Location: Prince George, British Columba, Canada

Silvatech developed several Total Chance Harvest Plans (TCHP) including the Ducette operating area, Prince George Business Unit, British Columbia, Canada for British Columbia Timber Sales (BCTS). The plan is one of thirteen carried out by Silvatech over a 3 year period. It encompassed over 17,000 ha that had only seen limited historic harvest related activity.

Using soft copy stereo technology, Silvatech identified all harvesting opportunities and identified the optimal location of all transportation infrastructure requirements for the entire operating area. This plan was verified and /or modified with supplemental, targeted field reconnaissance providing additional validity to the plan.

The plan afforded BCTS the flexibility to accommodate for other non-timber resource values by having complete knowledge of the operating area and the relative merchantability of respective harvest areas. It entailed carrying out a merchantability analysis for the Ducette area incorporating the costs and values associated with each harvest unit. Road construction, silviculture, harvesting, log transport, manufacturing, overhead, and road maintenance costs were all incorporated into the cost structure of each individual harvest unit. These costs were offset by the stand value extrapolated from stand composition and site characteristics. The resulting merchantability value, combined with the TCHP product, provided planners a detailed information matrix in which to base future land base management decision.

On Time. On Target. On Budget.
