GE Wei-hua · Jisuanji gongcheng · 2009
To meet the needs of labeling magnetic gradient characteristic of aeromagnetic contour map,methods based on solid-shadow algorithm and directional filtering technique are presented.After relative ubiety of magnetic field data is distilled,two types of graded distribution are obtained by solid-shadow algorithm and directional filtering technique respectively.The results of solid-shadow algorithm and filter-refinement processing make surface gradient feature very sharp and effective,which is valuable for overlap analysis.
