The web scene viewer has additional tiling scheme requirements that must be met for tile layers to be displayed correctly. These include:
- Each scale level must be half of the preceding scale level within a tolerance of 8-9 decimals.
- The tile size must be 256 by 256 when sharing to Portal for ArcGIS 10.4.1 or earlier. When sharing to Portal for ArcGIS 10.5 and ArcGIS Online, the tile size can also be 512 by 512.
- The scale of level 0 must fit within the extent of the layer.
- If you have access to the source data, re-share the existing tile service layer using a valid tiling scheme. To create a new tiling scheme, use Generate Tile Cache Tiling Scheme.
- Remove the tile layer.
- Each scale level must be half of the preceding scale level within a tolerance of 8-9 decimals. For example, if you have a tiling scheme with 3 levels from 2000 to 500, the scales would have to be: 2000, 1000, and 500. This analyzer would be triggered if you used 1500 instead of 1000.
- Although additional sizes are available, the most common tile sizes used in tiling schemes are 256 and 512. The scene viewer requires a tile size of 256 when sharing to Portal for ArcGIS 10.4.1 or earlier. Portal for ArcGIS 10.5 and ArcGIS Online additionally allow a tile size of 512.
- The scale of level 0 must fit within the extent of the layer. If the scale used for level 0 in the tiling scheme is too large, the tiles in level 0 will extend outside of the extent of the layer. Using a smaller scale for level 0 will ensure the tiles fit within the extent of the layer.
