Elevation data is a good example of a single-band raster dataset, often visualized with a color ramp, as shown in Figure 2.

高程数据就是很好的单级光栅数据的例子，它经常用颜色坡度，如图2所示。

Taking a 10-meter-by-10-meter grid and making one observation for each intersection (100 observations) would constitute a raster dataset.

比如 10 米乘 10 米的网格，取每个交叉点的值（共有 100组）就形成一个光栅数据集。
