Ecosystem Services Social Values Model

The Ecosystem Services Social Values Model works in conjunction with the Value Mapping Model to generate Value Index maps and landscape metrics describing the location and attibutes of areas that selected survey respondents value for reasons such as aesthetics, biodiversity, or recreation. The Ecosystem Services Social Values Model must be processes before the Value Mapping Model is used. It allows for the selection of a particular public use and an attitude or preference regarding that use for a subgroup of survey respondents. If no use and atittude or preference are selected, the model will run for all survey respondents; however, if either the public use or the attitude or preference parameter is selected, then both must be selected. Once the model finishes processing, a table named ClusterStats can be accessed through the ArcMap table of contents Source tab. The table includes average nearest neighbor statistics for each of the 12 social value types. The user can use these statistics to identify specific social value types they would like to examine using the Value Mapping Model. The Value Mapping Model can be processed repeatedly for each social value type of interest. For additional information regarding the Ecosystem Services Social Values Model, select the "Tool Help" button or consult the SolVES user manual.


Illustration


The Ecosystem Services Social Values Model generates weighted kernel density surfaces for each of 12 social value types. It then identifies the maximum value contained in each of these grids. Finally, it generates a constant "Maximum Grid" containing the highest single value found among all the weighted kernel density surfaces.

Model

Elements
Name Explanation
Create File GDB (2)

Creates the Results file geodatabase for final data.
Create File GDB

Creates the Scratch file geodatabase for intermediate data.
Survey_Parameters_Submodel

Converts user-entered public use and attitude or preference paramaters to a SQL statement which is used to select appropriate point features.
Make Feature Layer

Creates a feature layer from points selected by the Survey_Parameters_Submodel.
Value_Allocation_Stats_Submodel

Calculates the total value allocated to each social value type, which is later used for weighting kernel density surfaces.
Add Join

Joins the total allocated values calculated by the Value_Allocation_Stats_Submodel to their associated selected point features.
Copy Features

Copies the joined points and values to a seperate feature class to be processed by the Kernel_Density_Submodel.
Kernel_Density_Submodel

Calculates the weighted kernel density surface for each of the 12 social value types and generates a Maximum Grid. Also calculates the average nearest neighbor statistics for each of the 12 social value types. Currently all kernel densities are calculated with a search radius of 5000 meters and an output cell size of 450 meters.
