Can a raster be used to build a pyramid?
Geodatabase rasters with wavelet compression can also have pyramids built. There are three pyramid resampling methods available: nearest neighbor, bilinear, and cubic convolution.
How often do you need to build pyramids in ArcGIS?
Pyramids only need to be built once per raster dataset; after that, they are accessed each time the raster dataset is viewed. The larger the raster dataset, the longer it takes to create the set of pyramids. However, this also means you will save more time in the long run.
Where does the construction of a pyramid begin?
The construction of the pyramid begins at this coordinate and proceeds to the right and down. Mosaicking data to the left or above the raster dataset’s origin requires ArcSDE to shift it so that it remains the upper leftmost point. Shifting the existing raster dataset’s origin requires ArcSDE to rebuild the pyramid.
When to use bilinear interpolation for raster pyramids?
Bilinear interpolation is recommended for 1-bit TIFFs or IMGs. When mosaicking raster data in ArcSDE or in a file geodatabase, pyramids can be built on a raster dataset as raster data is being mosaicked into the raster dataset, or they can be built when the loading is complete.
When to use partial pyramid construction in ArcGIS?
ArcGIS allows partial pyramid construction, which rebuilds only the part of the pyramid overlapped by the source data during a mosaic operation. This helps when updating a mosaicked raster dataset, because if a new raster dataset is added, the entire raster dataset does not need to rebuild pyramids.
