Earlier this week I encountered an interesting phenomenon. Some output TIFF images in ArcMap kept displaying like the one below. I tried deleting pyramids, rebuilding pyramids, but to no avail. However, the images displayed perfectly well at < 1:250,000 map scale. Then I noticed that the image was 64-bit depth. It turns out that even though Esri supports 64-bit rasters for display not all functions work properly. I forwarded this to Esri support and it turns out that this is a limitation of the software not a bug. There are plenty of workarounds for this problem. Simply converting to 32-bit works. As does converting to a file geodatabase format. However, I think that having this out there as a known limitation in the blogosphere might do some good. Check out the link below for the list of supported raster formats in ArcGIS 10.3.

With this blog I intend to share GIS, remote sensing, and spatial analysis tips, experiences, and techniques with others. Most of my work is in the field of Landscape Ecology, so there is a focus on ecological applications. Postings include tips and suggestions for data processing and day-to-day GIS tasks, links to my GIS tools and approaches, and links to scientific papers that I've been involved in.
