Python 使用MapProxy TMS缓存OSM
出于开发目的,我想在ESPG:25832中使用MapProxy缓存OSM磁贴,并将其作为代理TMS服务提供 WMS/WMTS服务在QGIS中看起来不错,但在QGIS和OpenLayers中,TMS调整不正确 我有一个配置mapproxy.yaml文件,如下所示:Python 使用MapProxy TMS缓存OSM,python,gis,openlayers,openstreetmap,Python,Gis,Openlayers,Openstreetmap,出于开发目的,我想在ESPG:25832中使用MapProxy缓存OSM磁贴,并将其作为代理TMS服务提供 WMS/WMTS服务在QGIS中看起来不错,但在QGIS和OpenLayers中,TMS调整不正确 我有一个配置mapproxy.yaml文件,如下所示: services: demo: tms: wmts: wms: srs: ['EPSG:25832', 'EPSG:900913', 'EPSG:2154','EPSG:3857'] layers: - n

我将层作为TMS添加到QGIS中的示例url是{z}/{x}/{-y}.jpeg
QGIS和OpenLayers强制将该层重新投影到EPSG:3857,并调整其几何体,使其远离应该的位置-不知道为什么。
EPSG:25832建议您使用一个自定义的平铺网格,在这种情况下,url中的
{-y}
在OpenLayers中不会像预期的那样工作,您应该使用tileUrlFunction。请参阅相关内容:有许多可能的问题,请参阅使用TMS到TMS mapproxy缓存,该缓存不会移动任何东西
