Raster Displays with "Holes" after Building Pyramids

[RandalGreene1]

Good day,

We have a large 16-bit unsigned integer raster in GRID format in 9.3. Before building pyramids it displays fine when zoomed out to the entire layer (see before.jpg, attached).

After building pyramids to improve display performance, it displays with "holes" (see after.jpg, attached). When we zoom in, the holes go away. What is causing this and how can we overcome it?

Thanks in advance,
Randal Greene

Hi Roger,

To determine if this is a bug, we would need to obtain some data to test with.  I would suggest contacting Esri Support, so they can look over this, and log a NIM if needed.
