Cost page (for Grid Cell sampling)

This page of the sample design dialog allows input and analysis of costs associated with the sample design.

This page contains the following controls:

Total Area to Sample

Displays the total area of selected sample areas on the map. If no map is being used, this control allows you to input a theoretical sampling area.

Units

Units associated with the sampling area.

Grid Units

Units used to display the total area of grid cells to be sampled.

Gridded Sampling Costs

Fixed Planning and Validation Cost

This is the fixed cost associated with the design. This amount does not change with the number of samples.

Setup Cost per Area

This is the cost associated with mapping and preparing the sample area or room for grid cell sampling.

Sampling Cost per Grid

This is the cost associated with collecting and analyzing an individual grid cell.

Total Cost

This is the total cost for the sampling design, using the formula:

Total Cost = (Fixed Planning and Validation Cost)

+ (Setup Cost per Area) * (Number of Sample Areas or Rooms)

+ (Sampling Cost per Grid) * (Number of Grid Cell Samples)

 

For an illustration of how to analyze costs, please refer to section 5.4 in the VSP User’s Guide.
