Introduction

This script processes a table generated in GIS (ArcMap Pro 10.8.1) where cold-water features (e.g. seeps, springs) identified from thermal infrared imagery in July 2020 intersect with property parcels within Beaver Creek, Crooked Creek, Moose River, and Funny River in the Kenai River watershed, Alaska.

An online interactive map showing locations of thermal anomalies can be found at the following link: https://arcg.is/D18Hr

A full report on methods used by NV5 Geospatial Consultants can be found at the following link: Kenai River Tributaries - Thermal Imagery Technical Report.

For thermal imagery raster files, contact Kenai Watershed Forum at .


Full Table

This table displays all information associated with thermal anomalies identifed in the technical report, and the parcels on which they are located.
