With some of the most carbon dense forests in the world, British Columbia has long been a prime target for logging. These forests, which contain vast swaths of old growth and vital caribou habitat, are at risk of irreversible biodiversity loss. The areas most at risk are those that are within reach of pellet mills — facilities that convert lumber into wood pellets. These areas, known as “haul zones,” overlap with critical old growth habitat.   


Risk Map: Pellet Facilities Threaten Primary Forest and Caribou Habitat Research Group  |  September/November, 2021 


In an effort to identify the extent of old growth and caribou habitat at risk, WarthogIS, in collaboration with Research Group, conducted risk-based analyses by modeling network service areas of wood pellet mill haul zones across British Columbia. WarthogIS found the area of overlap between known old growth and caribou habitat and wood pellet mill haul zones to be nearly 845,000 hectares.  

In collaboration with Applied Survey Research (ASR), WarthogIS assisted in implementing the 2023 Point-in-Time (PIT) Count across several counties in northern California. PIT counts approximate the number of people experiencing homelessness in each community and assist the federal government in better understanding the extent and nature of homelessness nationwide.  The PIT count is conducted by survey researchers on a census tract by census tract basis and requires a visual enumeration of unsheltered persons and families experiencing homelessness, including those sleeping outdoors, on the street, or in parks, tents, or vehicles.  

2023 Point-in-Time (PIT) Count

Applied Survey Research (ASR)  |  November/December, 2022 


In order to accurately conduct the PIT count, survey researchers were assigned a census tract and provided with a detailed map delineating the assigned census tract as well as adjacent census tracts, roads (with labels), and parks.  In order to produce the 208 maps required for the PIT count, WarthogIS utilized complex geovisualization techniques to automate the production of maps without losing detail or vital geographic information. Once the maps were produced, a comprehensive review of all maps, one-by-one, was conducted to ensure that each map was legible and detailed enough to successfully guide the survey researchers in the field. 


To account for maps containing census tracts of varying size and street densities, detailed work with scale and map extent was required. For example, large census tracts containing a large portion of uninhabited space while also containing small areas of communities with a high density of streets required WarthogIS to split census tracts by hand and manually adjust the scale and extent of the maps until the required level of detail was achieved.  


By providing ASR with the necessary materials to carry out and report findings for the 2023 PIT count, WarthogIS played an important role in assisting service providers, policy makers, funders, and local, state, and federal governments in not only gaining a better understanding of the persons experiencing homelessness, but also measuring the impact of current policies and programming, and future planning efforts. 

With the growing concern among train derailments across the U.S., there has been a greater need for information regarding the extent and spatial distribution of rail lines carrying hazardous materials.  In an effort to shed light on this issue, WarthogIS was tasked with developing a nationwide dataset of rail lines carrying hazardous cargo, including locations of reported rail accidents.  


In order to produce an accurate, high resolution dataset at a continental scale, WarthogIS meticulously executed the process of manually selecting rail lines that met specific criteria based on historical rail accident data as well as rail classifications across the country. From this dataset, 1-mile buffers around every rail line carrying HAZMAT cargo were produced to both delineate evacuation zones and illuminate areas of greatest concern, such as those where rail lines carrying hazardous cargo ran through dense population, near water, and/or next to utilities.  


To convey this information in a meaningful and informative way, WarthogIS produced an interactive dashboard displaying the 1-mile evacuation zones, rail accident points, urban areas, and schools. This dashboard not only allowed users to click on features to learn more information, but as the user panned and/or zoomed around the map, the number of reported rail accidents (including the type) automatically updated to display information within the current map extent.  


In this way, WarthogIS achieved project goals by 1) creating a high quality dataset guided by a careful, comprehensive review of existing data and relevant attributes, and 2) producing an informative dashboard application for geospatial data that maintained a high level of detail and information at both large and small scales.
