This SOP explains how to generate rotational transects using ArcGIS Pro (v 3.3.1 as of this update) for the Pacific Island Network (PACN) Established Invasive Plant Species (EIPS) Monitoring Protocol. The procedures outlined in this SOP must be performed to generate new rotational and alternate transects for each sampling frame; fixed transects do not change and therefore should not need to be generated in the future. As transect locations may be shared between this protocol, PACN Landbirds Protocol (Camp et al. 2011), and Focal Terrestrial Plant Communities Protocol (Ainsworth et al. 2011), guidelines for all three protocols should be considered when generating transects. This SOP is based on available tools for ArcGIS used by the GIS specialist and represents one of many ways to accomplish these tasks. Once transects have been generated, SOP #9 Conducting Invasive Plant Species Surveys describes how to install contiguous plots along each transect.
