描述----------Description----------
Sink drainage route detection.
灌排水路由检测。
用法----------Usage----------
rsaga.sink.route(in.dem, out.sinkroute, threshold, thrsheight = 100, ...)
参数----------Arguments----------
参数:in.dem
input: digital elevation model (DEM) as SAGA grid file (default file extension: .sgrd)
输入:数字高程模型(DEM)SAGA的网格文件(默认文件扩展名:.sgrd)
参数:out.sinkroute
output: sink route grid file: non-sinks obtain a value of 0, sinks are assigned an integer between 0 and 8 indicating the direction to which flow from this sink should be routed
输出:片路线的网格文件:非汇获得的值为0,接收器被分配0和8之间的一个整数,表示这片流动的方向应改为
参数:threshold
logical: use a threshold value?
逻辑:使用阈值吗?
参数:thrsheight
numeric: threshold value (default: 100)
数字:阈值(默认:100)
参数:...
optional arguments to be passed to rsaga.geoprocessor, including the env RSAGA geoprocessing environment
可选参数传递给rsaga.geoprocessor,包括env RSAGAGEO处理环境
值----------Value----------
The type of object returned depends on the intern argument passed to the rsaga.geoprocessor. For intern=FALSE it is a numerical error code (0: success), or otherwise (default)
返回的对象的类型取决于intern参数传递的rsaga.geoprocessor。对于intern=FALSE它是一个数字错误代码(0:成功),或以其他方式(默认)
注意----------Note----------
I assume that flow directions are coded as 0 = north, 1 = northeast, 2 = east, ..., 7 = northwest, as in rsaga.fill.sinks.
我认为流动方向被编码为0 =向北,1 = 2 =东东北,...,7 =西北部,在rsaga.fill.sinks。
This function uses module 0 from SAGA library ta_preprocessor.
此功能使用模块0,从的SAGA库ta_preprocessor。
