Terrain Stability Mapping


Description:  Terrain Stability Mapping (TSM) is a RISC standard approach used to delineate areas of stable and/or unstable terrain including the assessment of the probability and any associated risks of landslides occurring. For information on FIA eligibility see: http://www.for.gov.bc.ca/hcp/fia/landbase/index.htm. For Resource Inventory Activity Area Expectations see: http://www.for.gov.bc.ca/hcp/fia/landbase/activities/resource_inventories.htm

Process: All projects will require an auditable workplan, clearly stating project objectives, methodology, and deliverables. The Terrestrial Ecosystem Information (TEI) Guidelines for Developing a Project Plan (PDF 232KB) provide an outline of the recommended process and a list of potential considerations pertaining to overall TEI project planning. (TEI projects include Terrestrial Ecosystem Mapping, Predictive Ecosystem Mapping, Sensitive Ecosystem Inventory, Bioterrain, Terrain, Landslide Inventory, Terrain Stability Mapping,  Wildlife Habitat Ratings, Species Distribution Modelling, and Soils projects.)  Recipients of FIA funding are required under their agreement with PricewaterhouseCoopers (PwC) to adhere to RISC standards, LBIP Standards, or an approved variance from the standards. A request for variance must be submitted to PwC who may then forward that request to the data custodian for review.

Delivery:  Project deliverables must in accordance with the Mandatory Standards listed below. All deliverables must be submitted to the appropriate data repository and the data custodian must be notified following the submission (see the Terrestrial Ecosystem (TEI) Information Data Submission page for details). Note, prior to data submission, a unique business area project identification number (BAPID), must be obtained from the data custodian (if a BAPID has not already been provided). The BAPID number is required for dataset/digital file identification. Requests for BAPID numbers should only be made once the detailed project plan is in place (see the Terrestrial Ecosystem Information (TEI)  Guildelines for Developing a Project Plan (PDF 232KB) for further information regarding this process).

Standards & Related Documents: The links below provides on-line access to the standards and other related documents including strategies, best practices, guidelines, and reports.

Before the commencement of any base mapping project, recipients must complete the Standard Operating Procedure. The purpose of this Standard Operating Procedure (SOP) is to provide direction to government agencies and partners with Government, in the documentation and procedures to be followed during the planning and implementation of mapping projects, inclusive of any aspect that relates to base mapping. The SOP will be applicable to mapping projects which have any component of Government funding for air photos, scanning, ortho photos, aerial triangulation and data exchanges involving such data.
