BoxletEstimatorSamplingFrame: BoxletEstimatorSamplingFrame

In Craig44/spatialsurvey: Gives access to a range of Design and Model-based estimators for two dimensional systematic surveys, particulraly systemtic spatial surveys

BoxletEstimatorSamplingFrame

Description

BoxletEstimatorSamplingFrame

Usage

BoxletEstimatorSamplingFrame(
  survey_polygon,
  quad_width,
  quad_height,
  quad_x_spacing,
  quad_y_spacing,
  boxlet_per_sample_width = 2,
  boxlet_per_sample_height = 2,
  trace = F
)

Arguments

survey_polygon	a spatial polygon that is the same coordinate reference as data.
quad_width	width of every sampling unit
quad_height	height of every sampling unit
quad_x_spacing	distance between sampling units on the x-axis
quad_y_spacing	distance between sampling units on the y-axis
boxlet_per_sample_width	is building 'boxlet_indicator_matrix' how many boxlets are in a sampling unit for x-axis, ignored if boxlet_indicator_matrix supplied
boxlet_per_sample_height	is building 'boxlet_indicator_matrix' how many boxlets are in a sampling unit for y-axis, ignored if boxlet_indicator_matrix supplied
trace	print messages as function progresses

Details

an auxillary functon that replicates the Boxlet variance estimator from Fewster 2011 Assumes rectangle/square survey region, assumes width and height of sampling units are constant quadrants or transects

Value

returns a list containing a fine lattice which represents all the boxlets.
