在利用ArcGIS处理数据时，有时需要对整个工作区域进行规则网格划分，这个在ArcGIS中是一件非常简单的事情，现在就将利用ArcGIS生成规则网格的步骤详细的介绍一下。 首先我有一个工作的范围，比如图一所示的范围： 图一 研究区范围 我要在研究区的范围内生成一个规则的网格，使其覆盖整个研究区域。比如说在整个研究区域生成5 km×5 km的网格。 （1）在ArcToolbos中，依次找到Data Management Tools—>Feature Class—>Create Fishnet，如图二所示。 图二 Create Fishnet位置 （2）在打开的对话框中进行如图三的设置，完成后点击确定即可生成网格，效果如图四所示。 图三 Create Fishnet设置 图四 生成的Fishnet效果 在图三中，Cell Size Width为网格宽度，Cell Size Height为网格高度，其单位为地图投影的单位；Number…

Why do we use the HSV colour space so often in vision and image processing?
The simple answer is that unlike RGB, HSV separates luma, or the image intensity, from chroma or the color information. This is very useful in many applications. For example, if you…
