Scott has 28 years’ experience in surveying and mapping, remote sensing imaging and GIS sectors. For the past 15 years Scott has be involved with airborne and mobile LiDAR applications.
Mobile LiDAR (Light Detection and Ranging) has become an established method for collecting very dense and accurate survey data for civil engineering applications. Mobile LiDAR surveys have several advantages over conventional ground survey techniques, including faster data collection, more detailed survey data, safer remote collection and cost effective for larger surveys. Mobile LiDAR systems can safely capture complete 360° coverage of corridors and survey assets in the systems field of view while driving at normal speeds.
The presentation will cover an overview of several of Tulloch’s recent engineering survey projects where mobile LiDAR played an integral part of the success of the survey. The focus will be on high accuracy surveying projects for transportation and municipal water/sewer applications, where mobile was used to increase the speed of the field work and greatly improve safety by keeping surveyors out of busy corridors. Each of the projects will be reviewed for the field data collection, required survey control data, processing methodologies, feature extraction and product generation to final engineering drawings. Including in the transportation project overviews will be projects covering MTO 400 series highways, Light Rail Transit (LRT) and the $4 billon Metrolinx Rail Electrification project. The talk will also cover a survey for the Brampton Victoria Feedermain project where mobile LiDAR data was used in conjunction with a conventional soft surface field survey to generate the final engineering survey plans for the 22-kilometre watermain.

Applying and developing remote sensing technology in the science and engineering areas has been an integral part of Mr. McArdle’s academic and professional career. Over the past 25 years, he has utilized hyperspectral, multispectral, microwave and LiDAR technology to provide visual solutions to quantify the changing world we live in. His LiDAR experience includes land cover mapping, flood inundations modeling, corridor feature extraction, route optimization, 3D shadow modeling for urban planning and dam safety assessment. Mr. McArdle was the lead author on the Canadian Federal Airborne LiDAR guidelines working with industry partners, academics and international organizations, including USGS to develop guidelines to support the National Elevation Strategy and floodplain mapping.
Airborne LiDAR data is well established commercial technology providing a unique textual information about the surface terrain and the physical features on the surface to high degree of detail. Inherently, LiDAR data is a collection of ambiguous pulse returns in three-dimension space and it is not until we apply some intelligence through numerical processing can we attach meaning to these points. In this workshop, the presentation will cover topics on nuance of LiDAR data, understanding the structure of the data, tools to visualize and harness your LiDAR data and more importantly; moving from picture to knowledge illustrated through applying LiDAR data for floodplain mapping, utilities, transportation corridors, and urban forestry applications.
LiDAR for Vernal Pool Identification & Archaeology
Christopher Menary Hon. BA | GIS Technician, Information Management
Toronto and Region Conservation Authority
Chris Menary is a GIS Technician with the Toronto and Region Conservation Authority where he uses geomatics on a wide range of projects such flood protection, erosion control, natural & cultural heritage studies, and agriculture. Chris holds an Honours Bachelor of Arts in Archaeology from the University of Toronto and further studied GIS at Ryerson University.
Vernal Pools are seasonal depressional ephemeral wetlands that are seasonally inundated and generally isolated from other watercourses. They provide a unique habitat with many organisms relying on them for their life cycle, such as Salamanders. These features are difficult to locate outside of their inundation period, and are also found in forests which limits the use of traditional orthophotography in their discovery. Two aspects of Lidar can be used to remotely detect Vernal Pools: a high-resolution DEM to detect depressions in the terrain and the intensity value of the returns to detect wet areas. A methodology was developed to identify areas that were both depressional and wet. This was then field-tested to examine the results and to further refine the process.
LiDAR can be used as a remote sensing tool to detect archaeological features. The only limitation is that it can only detect where the ground has been modified; this means it cannot be used in the detection of most indigenous sites in Ontario. By using the bare-earth DEM, Hillshade & Slope rasters features such as foundations, earthworks, and old agricultural plowlines can be observed even under tree cover. Detection can be manual, such as examining an area where a known farm was located, or automatic such as a script that identifies a combination of slope/aspect/flow direction and can survey a large area.

Credit Valley Conservation was covered by LiDAR products flown between Spring, 2015 and Fall, 2017. Acquiring LiDAR was a strategy to provide highly accurate data for various projects and programs across the organization for a cost that is constantly proving to be very reasonable. Some projects are now based completely on LiDAR, such as some of Mississauga’s creeks floodplain mapping and the Flood Damage Risk Assessment. In many site and neighborhood scale projects, the details that LiDAR is providing is substituting the need for field surveys and saving time and resources. The Cities of Mississauga, Brampton and Orangeville are actively using the LiDAR products for wide scale projects within CVC jurisdiction.

He is currently working with Topcon/Sokkia as a senior manager in the Mass Data section which includes mobile LiDAR, Terrestrial Scanning and UAV applications.
The supply of high resolution and survey grade geolocation data is one of the largest growing requirements in construction and engineering with BIM (Building Infrastructure Modeling) components. Along with applications in asset and as-built engineering projects the need for rapid and accurate survey grade information is paramount.
The presentation will deal with the technology and techniques in collecting datasets from active and passive systems and the use of such information in static environments as it pertains to critical engineering projects. The information presented will discuss the physical technology and theories, along with the software and potential workflows that can improve the desired results.
LiDAR for Urban Forestry
Forsite - Forest Management Specialists
Craig Robinson graduated with a Bachelor of Science in Forestry from the University of Toronto and has worked in the GIS and forestry industry for over 25 years as an analyst, developer, sales, and manager. Craig has worked in many business verticals throughout his career, providing solutions for industry, consulting, and all levels of government. Craig is currently an Analyst and Senior Project Manager with Forsite Consultants Ltd. Forsite provides unique value-added LiDAR products throughout Canada that focus on trees, forests, wildlife habitat, and terrain.
In this presentation, we’ll talk about adding value to LiDAR data for applications with trees and forestry. In general, there are two approaches to creating inventories of trees and forests from LiDAR. An area-based inventory approach provides a continuous estimate of key tree attributes ‘wall-to-wall’ – across an area of interest, often represented as a raster layer. Forsite is also putting a lot of emphasis on individual tree inventories, where LiDAR is used to create a wall-to-wall inventory of individual stems, with specific characteristics associated with each tree in the inventory. We’ll discuss some of the techniques and applications we are currently using for LiDAR-derived tree inventories.
