Hi Andrea, The DEM layer is a raster with 2 meters grid cell size covering Oklahoma area. The DEM has been separated into a tileset of 3.25 minute square GeoTiffs in Geographic Coordinate System WGS 1984 (EPSG: 4326). The tileset is processed by the Image mosaicking plugin. Each tile contains a single band with Float32 datatype and the following overviews: 1739x1739, 870x870, 435x435, 218x218, 109x109, 55x55
Attached the SLD definition. Thanks, Tamas Andrea Aime <[email protected]> ezt írta (időpont: 2019. okt. 23., Sze, 18:28): > Hi Ian, > do you have overviews in your DEM?
