是指在将栅格数据转换为多边形时,生成的多边形的节点数目。rastertoPolygons是一种常用的栅格数据处理方法,用于将栅格数据转换为矢量数据,以便进行空间分析和可视化等操作。 节点数是指多边形的顶点数目,它决定了多边形的形状和复杂度。节点数越多,多边形的形状越精细,能够更准确地表示原始栅格数据。然而,节点数过多也会...

The problem! Imagine you have this situation: you have several global raster files and a shapefile with a few areas (e.g. Natural Parks). You want to generate a raster file using as mask each of the polygons in the shapefile for each of the original rast
Clips a raster using a rectangular shape according to the extents defined or clips a raster to the shape of an input polygon feature class. The shape defining the clip can clip out the extent of the raster or clip out an area within the raster. ArcGIS Pro Basic Composite Bands Combines ...

Each edge of the polygon (e.g., a triangle) is represented by a linear edge function which classifies each pixel within the plane of the polygon. In particular, pixels having a value greater than zero are on one side of an edge and less than zero on the opposite side of an edge. ...
