Left but Not Forgotten: Mapping Waste Residue Piles in British Columbia using LiDAR and Photogrammetry

July 5, 2019/in Presentations/by Ted MacKinnon

The Canadian forestry sector is undergoing a period of rapid change due to the advancement and increasing affordability of modern geospatial technologies.

To support field operations, and to anticipate changing legislation within British Columbia regarding the measurement of waste residue as a product of logging operations, the presentation describes a case study performed by the Scaling and Remote Sensing departments at TDB Consultants comparing traditional field survey methods to both airborne LiDAR and photogrammetrically derived point clouds.

Assessing Set-Aside Old-Growth Forests with Airborne LiDAR Metrics

June 30, 2019/in Presentations/by Ted MacKinnon

Old-growth forests provide a variety of services to human populations such as water, carbon storage and ecotourism. Despite the value of old-growth forests, this resource is constantly under anthropogenic pressure. Airborne LiDAR Metrics were applied to estimate attributes of old-growth forests (ex. height, canopy cover, vertical complexity, understory density) and develop an index for old-growth forests.

This research brings light to OGMAs’ definition and their evaluation through the use of a relatively new technique, LiDAR. More importantly, the identification of the amount and location of old-growth forests over the landscape can aid to the conservation of this rare resource and its services .

Annapolis Valley Trails Coalition: An Enterprise GIS Solution

June 26, 2019/in Presentations/by Ted MacKinnon

Annapolis Valley Trails Coalition (AVTC) manages and maintains the Harvest Moon Trail that runs from Grand-Pré to Annapolis Royal through little towns, agricultural fields and along the Annapolis River. Over the course of the fall semester, students at COGS (Centre of Geographic Sciences) explored scalable Enterprise GIS solutions to manage trail assets. They modelled and built a spatial database and integrated it within desktop and web GIS solutions.

Dormant inland lifeways of Graham Island, xaadlaa gwayee

June 21, 2019/in Presentations/by Ted MacKinnon

In this talk I will demonstrate where one such trail is located. I shall describe the landscape archaeological approach I used to do indicate where the trail is, which employed a GIS to contain, map and analyse the results, and Google Earth to provide three dimensional views.

Updating the Online National Vector Cache Maps

June 15, 2019/in Presentations/by Ted MacKinnon

Esri Canada has developed an automated process for updating online national vector cache maps using the latest in contributor data. This presentation discusses the process and software used to do so.

10 Years of The Selkirk College – Columbia Basin Watershed Network Mapping Program

June 13, 2019/in Presentations/by Ted MacKinnon

Since 2008 Selkirk College’s Geospatial Research Centre (SGRC ) has provided the Columbia Basin Watershed Network (CBWN ) with mapping support.

Multi-faceted Approach to Studying Glacier Mass Change in the Columbia and Rocky Mountains

June 12, 2019/in Presentations/by Ted MacKinnon

Glaciers in the Canadian Columbia River Basin are in a state of retreat in response to climate change. Regionally, sparse data limits our ability to understand and quantify present and future changes to the alpine cryosphere.

Canada’s Human Footprint; Finding the Wild, Intact, and Human Dominated

June 8, 2019/in Presentations/by Ted MacKinnon

Canada is one of the signatories on the Convention on Biodiversity and its Aichi Biodiversity Targets. With these ambitious conservation targets, there is a need to better understand the distribution of threats to natural systems across the Canadian landscape. Global footprint maps have shown Canada as relatively ‘wild’ however, the threats mapped represent only a subset of threats relevant to Canada as the country still lacks a national scale cumulative threat study. Mapping threats to biodiversity on a national scale will help determine what systems are most intact and which areas are heavily threatened.

The Process and Challenges of Producing High Resolution Orthoimages in the Thousands Using Agisoft Photoscan

June 3, 2019/in Presentations/by Ted MacKinnon

With a total project area of 4363 km2 (more than 1.5 times the area of all of Luxembourg), producing 2136 orthoimages of the area surrounding BC’s Kootenay Lake (clipped to 1:2500 scale tiles at a 10 cm resolution) presented a host of challenges to be identified and surmounted.

Alberta Triple Prescription Program Atlas

June 3, 2019/in Presentations/by Ted MacKinnon

The purpose of the Triplicate Prescription Program Atlas is to provide an overview of provincial TPP medication utilization. It presents the data as tables, graphs, and maps.
