I am new to OSM and I would like you to help me with some questions I have. I’m styling my raster map of Europe.
I have the data from the European DB (downloaded from download.geofabrik.de) on my own server, I have the data filtered, I have created indexes and made a rendering to have the images in cache. All this to make my map load faster. With tilemill (to learn I have seen that it is simple although it is old-fashioned) I have created my style sheet and added a raster layer to it. The data for the raster I have downloaded from srtm.csi.cgiar.org.
My doubt: • When applying the raster layer with the data downloaded, I have noticed that in the Black Sea an area appears as with squares (marked with red cross) in the center which I would like to know how to eliminate so that the entire sea / water can be seen the same as in the rest of the Map. Any solution?
