DSsim 0.1.0
-----------
Introducing the new Distance Sampling Survey Design package!
dssd implements the following designs:
* Point transects: Simple random sampling
* Point trasnects: Systematic grid with random start point
* Line transects: Parallel random lines
* Line transects: Systematic parallel lines with a random start
* Line transects: Equal spaced zigzags with a random start
* Line transects: Equal spaced zigzags with complementary set of zigzags
dssd also implements the following feature options:
* Ability to vary design angle
* Survey generation by number of samplers, spacing or line length (can generate by different criteria in each strata)
* Ability to use different designs in each strata (as long as they are of the same type, i.e. all point or all line transects)
* Generate plus or minus sampling surveys
* Generate zigzag design inside minimum bounding rectangles (angled along the design axis) or convex hulls
* Calculates the coverage of different design by simulation
* Produces summary statistics from the coverage design showing the variability in number of samplers, line length, % coverage across surveys from a given design
