在R中创建道路网络数据集 [英] creating road network datasets in R

问题描述

我有一个包含道路的线shapefile，我想用它来创建网络数据集.在ArcGIS中，我可以使用Network Analyst扩展程序(请参见

I have a line shapefile containing roads, and I'd like to use it to create a network dataset. In ArcGIS, I'd do this with the Network Analyst extension (see here).

是否存在具有等效功能的R包?我已经检查了 Bivand的Cran任务视图用于空间分析数据，我在SO和 GIS SE 上进行了一些搜索，但我尚未找到任何好的线索.我还浏览了Bivand等人(2013)应用R进行空间数据分析.

Is there an R package with the equivalent functionality? I've checked out Bivand's Cran Task View for the analysis of spatial data, and I've searched a bit on SO and the GIS SE, but I haven't found any good leads. I've also looked through Bivand et al.'s (2013) Applied Spatial Data Analysis with R.

我已经使用R一段时间了，但没有用于空间数据处理和分析.对于任何有关其他资源的包装建议或技巧，我将不胜感激.

I've been using R for a while, but not for spatial data processing and analysis. I'd appreciate any package suggestions or tips about other resources.

推荐答案

您可以检查shp2graph软件包.它允许输入SpatialLines或SpatialLinesDataFrame(即通过maptools库中的readShapeLines函数加载的线shapefile)来创建网络.然后通过功能points2network将点数据集集成到现有网络中.例如，这些点可以是城市质心的坐标.然后，通过igraph程序包，您可以分析网络.

You could check the shp2graph package. It allows to input a SpatialLines or SpatialLinesDataFrame (ie. a lines shapefile loaded through the readShapeLines function in the maptools library) to create a network. And then through the function points2network integrate a points data set into an existing network. For example, these points could be the coordinates of city centroids. Then, through the igraph package you could analyze the network.
