EMAP Western Pilot Site Selection Process
- Driven by survey design specifications
- Create GIS coverage for boundary of study area
- Create hierarchical grid covering study area
- Ensure <1 point per grid cell
- Ensure grid cell small enough to be included in small regions of study area
- Create GIS coverage for sample frame
- Intersect frame coverage with grid coverage
- Determine multi-density multiplicative factors for unequal probability
- Select sites
- Create Design File

Step by Step Site Selection Example - Finite Population of Discrete Entities
Finite Population of Discrete Entities - 2 or more sites within cell
Continuous Linear Network Population - Streams
Continuous Areal Population - Estuary Example
