The tile size specified for fixed size tessellation is smaller than the tolerance as specified in the layer metadata.
The tile size specified for fixed size tessellation is smaller than the tolerance as specified in the layer metadata.
See the Oracle Spatial documentation for an explanation of tiling levels, tile size, and tiling resolution. Ensure that the tiling parameters are set such that any generated tile is always larger than or equal to a tile at the maximum level of resolution. This can be achieved by using a fewer number of tiles per geometric object or specifying a smaller tile size value than the current one.
