Sample design involves considering the management or research objectives of a project and tailoring the data collection process to satisfy them. This collection will continue to be updated and expanded as tools are developed to help to streamline the experience for project leads.
The Shiny spatially balanced sampling tool is intended to let users draw spatially balanced random sampling points within an area based on an ArcGIS polygon shapefile. If the shapefile includes multiple polygons and an attribute table field for stratification, the tool can take that into account to draw sample points by stratum as well.
A simple walkthrough of the tool can be downloaded here.
