“…The "cleanest" is dx. In an attempt to reduce noise levels, in addition to conventionally levelling methods, the micro-levelling method of Minty (1991) was applied to the data. However, despite significant time and effort there were no improvements and even some minor micro-levelling artefacts were generated.…”

“…Devido aos ruídos remanescentes do nivelamento convencional e associados às imperfeições do nivelamento das malhas após a interpolação, procedese ao micronivelamento (Minty 1991), que corresponde à aplicação de filtros que podem reduzir ou até excluir estas altas freqüências indesejáveis.…”

“…This effect was corrected by using a directional cosine filter (degree 6) along the flight direction, cancelling or at least reducing the distortions. More precise correction procedures (e. g., Green, 1987;Minty, 1991) were not available at the time the presented cps data were processed. Even so, the obtained maps are satisfactory tools for general geologic interpretations on a qualitative basis.…”
