1.Repair Geometry (Data Management) 几何图形修复，比如面图层不满足节点坐标逆时针
2.Raster Domain (3D Analyst) 获取栅格范围
3.Intersect (Analysis) 图层相交
4.Feature To Point (Data Management)
5.Create Random Points (Data Management)
Creates a specified number of random point features. Random points can be generated in an extent window, inside polygon features, on point features, or along line features.
6.Extract Multi Values to Points (Spatial Analyst) 从栅格图层提取点的属性值
7.Simplify Building (Cartography) 简化面图层的节点
8.Polygon To Line (Data Management) 多边形转换为线（ring） 多边形转换为多义线
9.Split Line At Vertices (Data Management) 将线从结点打断
10.栅格计算器 Raster Calculator (Spatial Analyst——Map Algebra)
11.栅格重分类 Reclassify (Spatial Analyst——Reclass)
12.将16位灰度图转换为8位灰度图。Mosaic to New Raster （Data Management Tools->Raster->Raster Dataset）
打开Mosaic to New Raster对话框，在Pixel Type（Optional）的下拉列表中选择8bit即可。
