  "Description": "Creates survey designs for distance sampling surveys.\nThese designs can be assessed for various effort and coverage\nstatistics. Once the user is satisfied with the design\ncharacteristics they can generate a set of transects to use in\ntheir distance sampling survey. Many of the designs implemented\nin this R package were first made available in our 'Distance'\nfor Windows software and are detailed in Chapter 7 of Advanced\nDistance Sampling, Buckland et. al. (2008, ISBN-13:\n978-0199225873). Find out more about estimating animal/plant\nabundance with distance sampling at\n<https://distancesampling.org/>.",
