osmnx 获取的建筑标签的准确性

【问题标题】：acutality of building tags fetched by osmnxosmnx 获取的建筑标签的准确性
【发布时间】：2021-05-11 10:27:35
【问题描述】：

有人能对建筑物及其标签的现状说些什么吗？
例如。我通过 OSMNX 获取https://www.openstreetmap.org/way/557584181，它说 building=construction，但在 OSM 上它说 building=office。我看到它是在大约 1 个月前编辑的。

不幸的是，我正在使用 OMSNX v. 0.9，因为我正在使用其他限制我使用 pandas=0.23 的软件包。

有什么想法吗？

编辑：

我猜它被缓存在某个地方。

【问题讨论】：

  • 您能否提供一个可重现的代码 sn-p 以便我们可以根据您使用它的确切方式查看 OSMnx 生成的内容。根据您的查询，OSMnx 会检索 OSM 的任何内容。

标签： osmnx


【解决方案1】：

如果您使用缓存的响应数据，它们将反映您缓存它们时 OSM 上的任何内容。您可以使用 config 函数关闭缓存。这是一个最小的可重现代码示例。

import osmnx as ox
ox.config(use_cache=False)
point = (47.6654265, 9.4464618)
gdf = ox.geometries_from_point(point, tags={'building':True}, dist=500)
gdf.shape #(137, 38)
gdf.loc[gdf['osmid']==557584181, 'building'] #office

一切正常。请注意，此时 v0.9 已经有好几年了，此代码示例使用 v1.0。
