matrix - OSRM距离矩阵

Question

我希望 OSRM 给我返回一个距离矩阵(就像 ArcGIS 的网络分析师一样)。

我注意到在 documentation这是通过调用 API 获得的。这适用于少量位置(就像示例一样)，但是，当我为 100 万个距离的矩阵提供 1000 个位置的列表时，它会削减我的 HTTP 请求，例如，即使是这个示例:

http://127.0.0.1:5001/table?loc=53.27528,-2.1271&loc=57.06322,-2.13991&loc=57.1913,-2.12272&loc=57.13205,-2.13559&loc=57.12008,-2.12476&loc=57.14234,-2.09557&loc=57.15555,-2.16155&loc=57.20477,-2.17626&loc=57.18151,-2.10008&loc=57.14901,-2.1&loc=57.15304,-2.13709&loc=57.14375,-2.1141&loc=57.14303,-2.11291&loc=57.14232,-2.11251&loc=57.13497,-2.12728&loc=57.14072,-2.12075&loc=57.12336,-2.13657&loc=57.12726,-2.11935&loc=57.14355,-2.10829&loc=57.13866,-2.09983&loc=57.13787,-2.08856&loc=57.13696,-2.0871&loc=57.10416,-2.08579&loc=57.06132,-2.12678&loc=57.06059,-2.12547

被截断为:

// http://127.0.0.1:5001/table?loc=53.27528,-2.1271&loc=57.06322,-2.13991&loc=57.1913,-2.12272&loc=57.13205,-2.13559&loc=57.12008,-2.12476&loc=57.14234,-2.09557&loc=57.15555,-2.16155&loc=57.20477,-2.17626&loc=57.18151,-2.10008&loc=57.14901,-2.1&loc=57.15304,-2.13709&loc=57.14375,-2.1141&loc=57.14303,-2.11291&loc=57.14232,-2.11251&loc=57.13497,-2.12728&loc=57.14072,-2.12075&loc=57.12336,-2.13657&loc=57.12726,-2.11935&loc=57.14355,-2.10829&loc=57.13866,-2.09983&loc=57.13787,-2.08856&loc=57.13696,-2.0871&loc=57.10416,-2

我想知道是否有其他方法可以将请求发送到本地主机服务器？理想情况下，我想要与 NA 相同的功能，我可以给它一个 50,000 x 50,000 个位置的矩阵，并在一天内对它们进行搅拌(截止时间为 20 分钟) - 这样的事情可能吗？

Answer 1

许多库在执行 HTTP 请求时都会限制 URL 的长度。 OSRM 本身对 URL 长度没有限制。不过，您需要更新一个 --max-table-locations 参数。

也就是说，对于相当大的请求，我建议使用我们的 node-bindings或 C++ 库 like in this example .
