CUBIC-Use cubic convolution with continuous data, such as satellite imagery or aerial photography.64_BIT- The pixel type will be a 64-bit data type supporting decimals.32_BIT_FLOAT- The pixel type will be a 32-bit data type supporting decimals.32_BIT_SIGNED- The pixel type will be a 32-bit signed data type.32_BIT_UNSIGNED- The pixel type will be a 32-bit unsigned data type.The values can range from -32,768 to 32,767. 16_BIT_SIGNED- The pixel type will be a 16-bit signed data type.16_BIT_UNSIGNED- The pixel type will be a 16-bit unsigned data type.The values supported can range from -128 to 127. 8_BIT_SIGNED- The pixel type will be a signed 8-bit data type.The values supported can range from 0 to 255. 8_BIT_UNSIGNED- The pixel type will be an unsigned 8-bit data type.The values supported can range from 0 to 15. 4_BIT- The pixel type will be a 4-bit unsigned integer.The values supported can range from 0 to 3. 2_BIT- The pixel type will be a 2-bit unsigned integer.1_BIT- The pixel type will be a 1-bit unsigned integer.The values of the cells in the raster will not be changed. LZ77-A lossless compression will be used.DEFAULT-The compression that is normally used by the raster dataset format will be used.
Pyramid Compression Type defines the method used when compressing the pyramids.

An expandable multidimensional raster dataset is created when you add a multidimensional data to an empty raster dataset using the Mosaic tool. The extent of an expandable CRF dataset is adjusted automatically by other tools that accept CRF as an input, such as the Mosaic, Copy Raster, Clip Rasters, and Resample tools.Īn expandable CRF dataset supports multidimensional rasters. The GIF format only supports single-band raster datasets.Ī raster dataset created in CRF format is expandable. When storing a raster dataset to a JPEG format file, a JPEG 2000 format file, or a geodatabase, you can specify a Compression Type value and a Compression Quality value in the geoprocessing environments. You can save the output to BIL, BIP, BMP, BSQ, CRF, DAT, Esri Grid, GIF, IMG, JPEG, JPEG 2000, PNG, or TIFF format, or any geodatabase raster dataset. You can then mosaic or load raster datasets into this location. When you create a raster dataset, you are creating an empty location to contain a single raster dataset.
