Applying GIS and geospatial data to reference condition approach stream assessments : guidance for Canadian Aquatic Biomonitoring Network participants / by Adam G. Yates, Edward M. Krynak and Wendy A....: En84-337/2023E-PDF

"The purpose of this guidance document is to provide participants of the CABIN program with a broad overview of Geographic Information Systems (GIS) and geospatial data and how they can be applied to stream assessments in CABIN. Specifically, the document presents information related to two objectives. First, a series of general considerations are described related to selecting appropriate data and ensuring their utility through proper metadata generation and quality assurance and quality control protocols (QA/QC) for CABIN. Second, the document provides detailed guidance on how CABIN participants can apply geospatial data to meet three key stream assessment objectives: 1) selecting test sites and reference sites; 2) building assessment models; and 3) interpreting assessment results. Although this document provides general guidance for CABIN participants, it is not a how-to or step-by-step guide related to using GIS; rather, the following content is to arm participants with the knowledge of how GIS can support comprehensive, robust and informed stream assessments. However, this document outlines the basic process that the user would follow for each application, and detail key considerations when applying GIS to CABIN-based stream assessments"--Document purpose, page 1.
