Interpreting the Metrics
Many different metrics were calculated to define the various characteristics that make up the Kenai Peninsula. Below is a detailed explanation of the metrics that are used across the 13 maps. Within the viewer this information is displayed on the window on the left side of the screen under the identify tab.
