 | This page is a work-in-progress. Generic message - Please note some detail may possibly be missing or incorrect. |
The FSX SDK QMID & LOD tables are inaccurate and can prove to be problematic when using resample.exe on source data that has been generated with the SDK values. Due to the rounding of the SDK values this can leave gaps one pixel wide in adjacent blocks of data.
This new table will hopefully resolve these issues in the photoscenery design process.
