contour interval

An Algorithm for Extracting Contour Lines Based on Interval Tree from Grid DEM

基于区间树索引的等高线提取算法

But, present range of fall contour interval this risk, should say or have the suitable distance.

但是, 目前的降幅水平距离这个风险, 应该说还是有相当的距离.

Contour interval is 10 feet.

等厚线距为10英尺.

In order to cater the 3-D showing of contour line, we should generate different contour interval lines and compatible with each others.

为了满足等高线三维显示的需求，需要等高距不同但彼此相容的等高线。

The accuracy of flood area is mostly dependent on the contour interval of map, accuracy of digitizing map, accuracy of DEM, and interval of GRID, detecting resolution of pixels.

对于采用本方法计算淹没区，准确性受地形图等高距大小、数字化采集精度、数字地面模型（DEM）高程精度以及格网间隔大小、像素探测分辨率等因素的影响。

Such structural features can be identified by contouring directly on either top or bottom surface of the reservoir with a contour interval of1-5m.

直接以油层顶面（或底面）为准绘制小等高线间距（1&5米）构造图，可显示出微型构造特征。
