I use deep forestry experience and imaginative geospatial analysis to reveal landscapes of insight.

I’m Jerome, an innovative geospatial analyst with 20 years of experience developing and communicating creative insights into complex questions.

My professional exploration of earth science began at McGill University’s Meteorology program and was crafted by years of practical experience and education in forestry, GIS, and leading-edge technology. I continually upgrade my skills, most recently in cloud-based GIS, data science, and software development.

My personal exploration of earth science began as a child, poring over atlases and viewing the landscape from the cockpit of a glider. Together, these explorations showed me the power of data and maps. I combine science-based analytical skills and technical communication with artistic creativity.

 Experience

GIS Analyst

Carson Integrated
2019 - Present

At Carson, I work with GIS that has moved from the desktop to the Cloud. I administer, manage, and troubleshoot an ESRI ArcGIS Online platform where geospatial data is hosted and served to field crews working for clients across northern Alberta, who in turn collect GPS-referenced ground data for block and road layout, and upload it to online maps.

I conduct Timber Supply Analysis (TSA) using Patchworks software and carbon modeling using the Canadian Forest Service’s General Carbon Budget Model (GCBM).

At the company woodlot, I experiment with new technology for forest mensuration, such as terrestrial LiDAR, which can be combined with drone-based aerial LiDAR to map every tree in the forest. This will enable accurate modelling of carbon sequestration to earn credit in emerging carbon markets.

Selected Projects

Prioritizing Seismic Cutline Reclamation for Caribou Recovery

Problem

There are 100,000 km of seismic cutline within caribou ranges in the oilsands region of northeastern Alberta. Planning for caribou habitat restoration required a method of prioritizing lines for reclamation treatments.

Solution

In consultation with stakeholders, I developed a prioritization algorithm (“bang for buck”) that calculated, for each township, the reduction in disturbed habitat resulting from reclamation (the “bang”), per length of line restored (the “buck”).

Measuring Functional Recovery of Seismic Cutlines Using LiDAR

Problem

Seismic cutlines are a pervasive disturbance in the boreal region of Alberta, but there is no information on revegetation or recovery status. Vegetation height can be derived from a high-resolution LiDAR-derived canopy height model (CHM), but manually digitized line features are not accurate enough to be overlaid with the CHM.

Solution

I wrote a Python script to cursor through each line feature and automatically redraw the line to follow a least-cost path using the LiDAR canopy height model as a cost surface. The resulting line can be overlaid on the CHM and attributed with statistics on vegetation height. This dataset was used to determine thresholds of wolf movement speed as a measure of functional recovery with respect to wolf predation on caribou (Dickie et al, 2017).

Erasing Roads from a Digital Terrain Model

Problem

Roads are represented in a LiDAR-derived Digital Terrain Model (DTM) as raised features which interfere with the modeled flow of water.

Solution

I developed a geoprocessing workflow to interpolate elevations within road right-of-ways, effectively “erasing” roads from the DTM, thus enabling correct hydrological simulation and providing a pre-anthropogenic “reference” condition for Alberta’s terrain.

Defining Lake Watersheds

Problem

There are 127,000 lakes in Alberta greater than 1 ha in size, but their catchment, or contributing area, remains undefined. Any hydrological analysis of lakes first requires a delineation of the catchment.

Solution

Using a high-resolution LiDAR-derived DTM, I wrote a Python script to automatically define catchments for 8000 of the major lakes in the boreal region of Alberta.
