These data contain observation and null polygons for waterfowl aerial surveys of Lake Michigan collected through the years 2009-2014. Polygons were created adjacent to either side of the flight lines (transects). The right and left offset of the polygons from the flight path, was determined using the average altitude of the plane along the transect and the observation angle through the plane’s window. Observed birds were counted and identified by species. This count data was attributed to the polygon closest to the point along the transect where the observation occurred, and on the side of the plane in which the observation took place. The point data represent counts where each point represents a single species....

Geographic patterns can change through time and/or across space, and these changes can lead to differences in the movement pattern and body condition of organisms, their interactions with each other and their environment, and ultimately lead to population and community-level changes. When quantifying landscape patterns using remotely sensed data, it is important to recognize that each pixel (i.e. picture element) has a temporal and spatial context. A pixel’s temporal context refers to its past and present classification. The spatial context of a pixel depends on the classification of neighbouring pixels, and the size of the area considered as the neighbourhood. Despite the fact that pixels are the basic unit of...

This ArcGIS Add-In tool assigns telemetry receivers a “river address,” with the National Hydrography Dataset (NHD) flowlines providing the river name (analogous to a street name in a postal address) and a distance along flowline (the house number in a postal address). Using this information, it is possible to sequence receivers along a flowline. Once sequenced, receiver data can then be analyzed to identify where receivers are being bypassed by receiver tags, or if there are instances of improbable tag movement between receivers.

Batch Kernel Density Tool Author: Timothy Fox, Upper Midwest Environmental Sciences Center, 2630 Fanta Reed Road, La Crosse, Wisconsin 54603 Platform developed: ArcMap 10.5 Addin The Batch Kernel Density Too is an ArcGIS ArcMap add-in developed at UMESC. When using this tool, a user can perform a magnitude-per-unit area analysis using point or polyline input data across multiple search radii (Figure 1). Files -FoxBatchKernelDensityTool.esriAddInn this is the compiled ArcGIS AddIn file that can be added ArcGIS 10.5 Installation: To install this tool: within a session of ArcMap 10.5, open the Add-in Manager dialog click the Options tab add the folder location to where you locally download the file FoxBatchKernelDensityTool.esriAddIn...

Executing the Dwell Time analysis condenses receiver/tag records into readable records of fish movement and receiver effectiveness. Fish movement is described by a temporal sequence of receiver/tag events (durations), where a tag is visible to a specific receiver or collection of receivers. The number and frequency of contacts within a receiver/tag event are summarized by the analysis. A receiver/tag event ends, and a new receiver/tag event begins when the tag is visible to a different set of receivers. Additionally, the Dwell Time analysis identifies which receivers have overlapping detection ranges and identify which receivers are potentially being bypassed by tagged fish. The SQL code included here is run...
