Chapter 17 Seasonal Migration Collection
The Seasonal Migration Collection allows agencies to incorporate annual movements of susceptible hosts to update risks across the landscape. The Seasonal Migration Collection is unique compared to the other data Collections, in that it stores and uses spatial data. The Seasonal Migration Collection is particularly useful while running the Hazard Model 2.0.
17.1 Understanding the Seasonal Migration Collection
Map layers must be uploaded in GeoJSON format, a common open-source format which can be created using most geographic information system (GIS) software.
17.3 Multiple migration paths are possible
Several CWD-susceptible cervid species may share select portions of the landscape, with different herds moving into and out of different areas. This Collection is able to capture as many polygons as necessary to accurately depict herds in each Administrative area.
In Visualizations, any feature attributes will be displayed in pop-ups.
