In the key step of this method (the process of contour tracking), the paper puts forward the concept of grid right-correlation flag to determine the initial segment of tracking curve. In the tracking procedure, the trend of subsequent points are determined by the combinatorial values of neighborhood cells, and a method is designed to avoid contours crossing. In order to obtain high-quality contour line, it adopts it adopts the linear interpolative method to show a contour chart of accurate localization and better visual effect.

在该方法的关键过程中，提出栅格右关联标志的概念，并据此确定初始追踪段；追踪过程中依据邻域栅格值的组合特征确定后续点的走向，设计了避免等值线交叉的处理措施；为获得高质量的等值线图形，采用线性插值方法，得到准确定位和视觉效果较好的等值线图形。
