Grid-hierarchical Sampling

Define a hierarchical grid to sample from. Sampling from a grid simplifies all data processing and links to other data sources. Cost and logistics usually require sampling, so that sample locations appear clusters in the landscape. Choose top-level grid with a size that is appropriate for the dimensions of your strata example. Choose the lower level grids using the standard dimensions recommended. Display your selected grids on a map. Here we need a simple map as an example than the complex hierarchical modeling.
