InletTracker: A Python tool for monitoring ICOLL entrances and shoals from publicly available satellite imagery

Start time: 12.00pm AEST. Join us for an introduction to InletTracker, a new tool for reconstructing and monitoring the dynamics of intermittent coastal inlets and similar landforms over the last 30+ years.
InletTracker: A Python tool for monitoring ICOLL entrances and shoals from publicly available satellite imagery

Despite their high ecological and socio-economic significance, there is often a lack of knowledge on the long-term dynamics of intermittent coastal inlets such as those found at intermittently open and closed lakes and lagoons (ICOLLs) or barrier islands. Australia alone is home to 305 (21%) of the 1477 globally mapped ICOLLs and for many of them, there are no long-term records of their time-evolving entrance state, which represents a challenge for coastal managers and decision-makers. 

In this talk, Tino will introduce InletTracker, a new tool for reconstructing and monitoring the dynamics of intermittent coastal inlets or similar landforms over the last 30+ years from publicly available Landsat 5, 7 and 8 and Sentinel-2 satellite imagery. InletTracker is a Google Earth Engine enabled python tool that uses a novel least-cost path finding approach to trace inlet channels along and across the berm, and then analyses the resulting transects to automatically infer the minimum channel width and whether an inlet is open or closed. The tool is free and easy to use and provides users with long-term data on the location and shape of entrance channels, the width of entrance channels at the bottlenecks (i.e., at the throat) and the open vs. closed state of an inlet. To demonstrate the usefulness of the tool for coastal engineering and research, Tino will provide a variety of application examples for ICOLLs around Australia as well as other parts of the world.
