Restoring magnetic anomalies

Data processing chain for high spatial resolution magnetic survey: Application on the Neolithic site of le Pontet (Charente‐maritime, France)

“…and others. Many authors had developed various processing to eliminate and correct these errors to obtain a quality magnetic map (Becker, ; Ciminale & Loddo, ; Eder‐Hinterleitner et al ., ; Gallo et al ., ). Thus, it is essential to process the magnetic data and we use three discriminate criteria to identify and remove outlier values (Figure ): The first criterion is the difference between the two magnetic values recorded by sensors (left and right) for the same measurement (Figure (a)).…”

“…Processing has been proposed and undertaken to correct these effects (e.g. Eder‐Hinterleitner et al ., ). Nevertheless, in the last few decades, researchers have used complementary instruments for recording the location of magnetic measurements such as real time global positioning system (GPS) (Gaffney, Gaffney, Cuttler, & Yorston, ) or total station (Ard et al ., ; Böniger & Tronicke, ; Lehmann & Green, ).…”

“…Furthermore, it requires advanced data processing to recover as much possible information on archaeological structures. Many authors consider these topics for characterizing disturbance sources and errors and also propose algorithms to correct them (Ciminale & Loddo, ; Eder‐Hinterleitner et al ., ; Gallo et al ., ). These processing steps show their effectiveness and utility for the enhancement of the magnetic map and their interpretation.…”

Advances in Reconstructing Archaeological Magnetic Signals; an Algorithm for Filtering Noise due to the Ploughing Effect

“…After that, they were visualised as 8 bit raster images to identify the presence of the most common undesired contributions (spikes, stripes and zigzag effects) (Figure a) which very often affect recorded data, thereby reducing the readability of archaeological signals (e.g. Scollar et al ., ; Eder‐Hinterleitner et al ., ). In order to correct such noise, a software package (Ciminale and Loddo, ) was successfully applied.…”

“…Dans un second temps, la médiane de chaque profil a été mise à 0 afin de retirer les effets de linéation parallèle dues aux différences de réglage des capteurs et à l'alternance du sens de parcours des profils (Eder-Hinterleitner et al, 1996). Les données ont ensuite été interpolées selon une maille de 0,5 × 0,1 m en utilisant la méthode de courbure minimum.…”
