Overview

simfish can be used to simulate movement tracks and acoustic detections in featureless and semi-realistic environments. Users can generate an environmental raster - a raster of land and water features - using the built-in generate_env function. This function generates both a land raster and two gradient rasters that are used to keep simulated tracks off of land via a potential function. Alternatively, users may supply their own environmental rasters (e.g., generated from an ESRI shapefile or similar) when a fine-scale simulation in a high-resolution environment is required.
