LTExercise: Simulated line transect survey data

In Distance: Distance Sampling Detection Function and Abundance Estimation

Simulated line transect survey data

Description

Simulated line transect survey. Twelve transects, detection function is half-normal. True object density is 79.8 animals per km^2.

Format

A data.frame with 106 rows and 7 variables

• Region.Label strata names (single stratum)

• Area size of study area (1 in this case, making abundance and density equal)

• Sample.Label transect ID

• Effort length of transects (km)

• object object ID

• distance perpendicular distance (m)

• Study.Area name of study area

Note

There is no unit object associated with this dataset
