iClient-JavaScript maplibre-gl-enhance 的style->sources->type: 'raster'设置tileSize: 512无效

如题，在使用maplibre-gl-enhance，加载wtms服务时设置tileSize: 512，经验证设置为256或者不设置或者设置512，地图都只能加载256的wtms服务

谢谢你提的issue。你是说OGC的WMTS服务吗？可以先确定下你的服务是否支持512的瓦片。请提供下下你的代码和WMTS服务的能力文档，便于我们跟踪问题。

使用的标准的EPSG:4498坐标系，代码如下：

你的wmts服务能出512的瓦片吗，通常情况下wmts都只是256的瓦片，请提供下你的wmts capabilities文档

你现在得现象是什么，wmts getTile请求是否发出，回来得是否是512得瓦片？

Sep 26 '24 07:09 songyumeng

能否提供在线的wmts服务地址

返回的瓦片不在范围内，我们数据涉密，不能提供在线的

没有能调试的服务，我只能猜测下问题原因:

通过你设置的bounds :2.0184047248447325E7，2103881.962779923，2.0815952751552675E7，5714206.250336334 可得bounds宽度为631905.5031053498，高度为3610324.287556411。

maplibre-gl-enhance 内部的逻辑为，宽高的最大值/512为第0级的分辨率，即3610324.287556411/512=7051.414624133616。r然后用bounds的左上角和计算出的第0级分辨率，构建瓦片金字塔。

但是该WMTS服务的0级分辨率为1234.1904357526364。这可能就是无法请求到正确瓦片的原因，并不是去请求了256的瓦片。

你提供的WMTS的Capabilities的内容格式错乱了，猜测其中的5714352.0 2.0184047248447325E7是TopLeftCorner，即该WMTS服务的瓦片左上角。根据前面提到的maplibre-gl-enhance 内部的逻辑，要让maplibre-gl-enhance内部的瓦片金字塔与你的WMTS服务的瓦片金字塔匹配，new CRS的bounds左上角需要是TopLeftCorner的值，即bounds应该调整为2.0184047248447325E7，2103881.962779923，2.0815952751552675E7，5714352.0

maplibre-gl-enhance目前不支持自定义级别对应的分辨率。所以为了能出图只有尝试修改new CRS的bounds，让mapboxgl-enhance内部计算的瓦片金字塔0级分辨率与WMTS的0级分辨率对应上。在左上角固定的前提下，WMTS服务的第0级分辨率为1234.1904357526364，可知bounds的最大宽高都应该为1234.1904357526364*512=631905.5031053498。那bounds应该调整为2.0184047248447325E7，5082446.49689465，20815952.751552675，5714352.0。

这个bounds和本身服务的bounds差别很大，需要确定是否能完全包含你的数据，如果没有完全包含的话，就会出现地图加载不完整的情况。

综上：如果根据我的解释计算出的bounds能概括你的数据范围，可以尝试加载。如果没有完全包含，那目前maplibre-gl-enhance无法加载你提供的这个服务。

maplibre-gl-enhance支持自定义级别对应的分辨率的功能我们正在规划中。
