analyseMagnetic: Analyse geomagnetic data from archaeological context

In ISAAKiel/magAAR: Process geomagnetic field data from archaeological contexts

Description

Analyse geomagnetic data from archaeological context

Usage

analyseMagnetic(anomalies_sdf, magnetic_raster, searchradius = 2,
  dipolfactor = 2, angle_steps = 10, get_profile_values = FALSE,
  get_dipol = FALSE, method = "avg", cut_value = 1.5, dipol_minima = -4)

Arguments

anomalies_sdf	Spatialdataframe: Point data containing the Anomalies
magnetic_raster	RasterLayer: Geomagnetic data (nT)
searchradius	The Radius around every anomaly that is under observation
dipolfactor	1. version of defining a dipole: The factor used to descripe a dipole; A dipol is defined by |minimal value * dipolfactor| > maximal value
angle_steps	Profiles are generated around the anomalie points in steps of angle_steps degrees
get_profile_values	Calculating the values of all profiles (TRUE)
get_dipol	Identifing the dipoles (TRUE)
method	method for calculating the profile values avg = Average width of all profiles; median = Median width of all profiles
cut_value	nT-value at which the width of the amplitude will be determined
dipol_minima	Additional defining of a dipole: All anomalies with min nT < dipol_minima in the profile are defined as dipoles

Value

A spatial data frame with the results of the dipole identifing (0/1) or/and the width and heigth of the amplitudes

Examples

sum(1:10)
