Ontario Basic Mapping (OBM): City of Peterborough - Sheet 02 17 7130 49040 (1989)

This map is part of the historical 1:2000 City of Peterborough, Ontario Base Mapping (OBM) series, which was published in two phases between 1987 and 1989. The OBM Program, initiated by the Ministry of Natural Resources, aims to create detailed topographic maps of the province using high-resolution aerial photography and ground-level surveys. The Phase 1 series consists of 45 maps that primarily depict the developed areas of Peterborough, utilizing aerial imagery taken in April 1985. The Phase 2 series includes 36 maps that cover the fringe areas, with imagery captured in May 1988. In total, there are 81 maps, all produced under contract with J.D. Barnes Ltd., Surveyors, and adhering to the mapping specifications set by the Ministry of Natural Resources. Each topographic map features 1-meter contours and represents an area of approximately one square kilometer (22x23 inches). After scanning, the maps underwent processing that included alignment, color correction, and sharpening, before being exported at 300 dpi in RGB format. The georeferencing of the maps employed the UTM grid, utilizing a minimum of 8 to 12 evenly spaced control points and a second-order polynomial transformation.

Invasive Vegetation Areas and Management Strategies

Overview This feature service provides comprehensive spatial data on invasive vegetation within the Trent University Green Network, along with detailed records of management efforts aimed at controlling these species. The Land Stewardship Team at Trent University's Symons Campus has been collecting data on invasive species through both incidental and methodical surveys since 2022. Relevant Resources: [Nature Areas Management Plans] and [Ggwepnandizamin]. Feature Layers * Invasive Vegetation Areas: This layer maps the geographic locations of various invasive plant species found within the green network. It includes data on species type, abundance levels, community classifications, and size of affected areas. The layer also captures the collection methods used during surveys and identifies control constraints relevant to terrain or environmental conditions. * Invasive Vegetation Areas Management: This table documents management activities applied to invasive vegetation patches, detailing the management methods used such as herbicide application, pulling, and selective cutting. It also records the year when management took place and categorizes the invasive species being addressed. Geographic Coverage This service geographically focuses on the Trent University campus lands, providing targeted information for managing and monitoring invasive vegetation within this specific region.
Ecological Land Classification

The Land Stewardship Team at Trent University's Symons Campus conducted the initial mapping of vegetation units through aerial photo interpretation, followed by ground-truthing in the field to verify the type and extent of each community. Species identification and abundance estimates, ranging from dominant to rare (based on definitions from Lee et al., 1998), were performed across all four vegetation layers: canopy, subcanopy, shrub, and ground. This detailed botanical inventory enabled the assessment of botanical quality within the site. Smaller communities, typically less than 0.5 hectares, were delineated as distinct vegetation types where feasible, leveraging the improved resolution of aerial imagery and the smaller project scale. The practical applications of this detailed vegetation mapping include analyzing percent cover and habitat diversity, as well as identifying priority areas for preservation and restoration. Data collection was conducted in the field across various nature areas from 2021 to 2024, with additional gaps filled in 2025. North-south Environmental updated this layer in December 2025 using data from the Land Stewardship team. This data is used daily by the team during fieldwork and is updated every five years or as new habitats are restored or created. The ongoing use and periodic updates of this data ensure that the ecological integrity of the nature areas is maintained and enhanced, supporting informed decision-making for conservation and land management efforts. For more information, please refer to the Nature Area Management Plans, which contain classifications for each nature area as well as descriptions of the communities within them.
