从 PostGIS 查询未公开的属性
Query not exposed attributes from PostGIS
我使用 osm2pgsql 将 osm 文件加载到 PostGIS 中。现在，我想查询具有特定属性的特征。例如："highway is not null" 和 "maxspeed is not null"。
PGadmin returns: "ERROR: column "maxspeed" 不存在"
我从 overpass-turbo 知道，我感兴趣的领域提供了这样的特性。
所以应该在场。
select * from planet_osm_line
where highway is not null and maxspeed is not null
我希望查询结果带有 "maxspeed" 的附加属性列，但是
PGadmin returns: "ERROR: column "maxspeed" 不存在"
看到一个similar question at gis.stackexchange.com. Quoting the answer:
The default.style file
https://github.com/openstreetmap/osm2pgsql/blob/master/default.style
does not pick maxspeed into its own column. Edit default.style or use
the --hstore option for writing all the tags into hstore.
