Description	VSP (Visual Sample Plan) provides statistical solutions to sampling design using mathematical and statistical algorithms, and a visual interface, while answering two important questions in sample planning: How many samples are needed, and where should the samples be taken ? The algorithms involved in determining the number of samples needed can be quite involved and intimidating to the non-expert. The program can calculate the number of samples needed for various scenarios at different costs. Sample placement based on personal judgment is prone to bias. The method provides random or gridded sampling locations overlaid on a user-input site map.
