Question

Does anyone know how to generate a map with FME, I met a resolution issue when creating base map. The wms link looks good in QGIS, but when use FeatureReader in FME, use bbox to get the wanted are, the resolution is super low.

What have you set for the Map Height and Map Width parameters on the WMS reader?

I tried with the bbox which is also the map area's width and height, but the resolution didn't change

The values you enter there are the pixel size of the result you're getting back, so depending on the units of the data and the native resolution of the underlying raster data using the bounding box size will not yield a high-res result.

 

Try changing them and see what happens.
