网络分析：多边形服务区域

[英]Network Analysis: Polygon service areas

原文 2017-02-27 22:23:33 3 1 gis/ arcgis/ arcmap/ network-analysis

I'm trying to run a network analysis and was wondering if there was a way to have the service area facilities as polygons instead of points? 我正在尝试运行网络分析，并想知道是否有办法将服务区设施作为多边形而不是点？

I've tried the feature to point tool but this create one point which doesn't account for the whole area of the polygon. 我已尝试使用该功能指向工具，但这会创建一个不考虑多边形整个区域的点。

Is there a tool that creates multiple points that outline the polygon? 是否有工具可以创建多个轮廓多边形的点？

I'll try to answer the first paragraph (I am not sure I fully understand connection with the second part). 我会尝试回答第一段（我不确定我是否完全理解与第二部分的联系）。

Besides buffers, readily available in ArcMap, with an ArcGIS Desktop extension one can crate Drive Time polygons around point features: 除了在ArcMap中随时可用的缓冲区外，还可以使用ArcGIS Desktop扩展程序在点要素周围创建“驱动时间”多边形：

With Business Analyst extension, Drive Time polygons can be created using the eponymous tool: 通过Business Analyst扩展，可以使用同名工具创建Drive Time多边形：
http://desktop.arcgis.com/en/arcmap/latest/tools/business-analyst-toolbox/drive-time.htm http://desktop.arcgis.com/en/arcmap/latest/tools/business-analyst-toolbox/drive-time.htm
As they state, 正如他们所说，

You can create more advanced drive-time polygons with custom road networks, adding barriers, and the like with the ArcGIS Network Analyst tools 您可以使用ArcGIS Network Analyst工具创建更多高级驱动时间多边形，其中包含自定义道路网络，添加障碍等
With Network Analyst extension, Make Service Area Layer tool is available: 通过Network Analyst扩展，可以使用Make Service Area Layer工具：
http://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/make-service-area-layer.htm http://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/make-service-area-layer.htm

After creating the analysis layer with this tool, you can add network analysis objects to it using the Add Locations tool, solve the analysis using the Solve tool, and save the results on disk using the Save To Layer File tool. 使用此工具创建分析图层后，可以使用“添加位置”工具向其添加网络分析对象，使用“求解”工具解决分析，并使用“保存到图层文件”工具将结果保存到磁盘上。
With Network Analyst extension, Generate Service Areas could be used for setting up a service areas Geoprocessing service: 通过Network Analyst扩展， Generate Service Areas可用于设置服务区域地理处理服务：
http://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/generate-service-areas.htm http://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/generate-service-areas.htm

Creates a service area network analysis layer, sets the analysis properties, and solves the analysis. 创建服务区域网络分析图层，设置分析属性并解决分析。 This tool is ideal for setting up a service area geoprocessing service on the web. 此工具非常适合在Web上设置服务区域地理处理服务。 A network service area is a region that encompasses all streets that can be accessed within a given distance or travel time from one or more facilities. 网络服务区域是包含可以在一个或多个设施的给定距离或旅行时间内访问的所有街道的区域。

Example: 例：
http://server.arcgis.com/en/server/latest/publish-services/windows/gp-service-example-drivetime-polygons.htm http://server.arcgis.com/en/server/latest/publish-services/windows/gp-service-example-drivetime-polygons.htm
With an an ArcGIS Online for organizations account , one can consume a ready to go service: 使用an ArcGIS Online for organizations account ，可以使用随时可用的服务：
http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/itemdesc-generate-service-areas.htm http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/itemdesc-generate-service-areas.htm

It is a service that runs like a geoprocessing tool within ArcMap, can be accessed from other applications, and includes high-quality road data for much of the world. 它是一种在ArcMap中像地理处理工具一样运行的服务，可以从其他应用程序访问，并包含世界上大部分地区的高质量道路数据。
