神奇的Copy Raster
工具位置：
Copy Raster <- Raster Dataset <- Raster <- Data Management
功能如下：
1. convert raster to other format /修改数据格式相同于coversion tools中raster to other format raster。在output raster dataset中除了name of output，同时指定要转换成的file extension。如下：
- .bil for Esri BIL
- .bip for Esri BIP
- .bmp for BMP
- .bsq for Esri BSQ
- .dat for ENVI DAT
- .gif for GIF
- .img for ERDAS IMAGINE
- .jpg for JPEG
- .jp2 for JPEG 2000
- .png for PNG
- .tif for TIFF
- .mrf for MRF
- .crf for CRF
- No extension for Esri Grid
2. change “pixel type” /更改数据像素类型
- 1_BIT —A 1-bit unsigned integer. The values can be 0 or 1.
- 2_BIT —A 2-bit unsigned integer. The values supported can be from 0 to 3.
- 4_BIT —A 4-bit unsigned integer. The values supported can be from 0 to 15.
- 8_BIT_UNSIGNED —An unsigned 8-bit data type. The values supported can be from 0 to 255.
- 8_BIT_SIGNED —A signed 8-bit data type. The values supported can be from -128 to 127.
- 16_BIT_UNSIGNED —A 16-bit unsigned data type. The values can range from 0 to 65,535.
- 16_BIT_SIGNED —A 16-bit signed data type. The values can range from -32,768 to 32,767.
- 32_BIT_UNSIGNED —A 32-bit unsigned data type. The values can range from 0 to 4,294,967,295.
- 32_BIT_SIGNED —A 32-bit signed data type. The values can range from -2,147,483,648 to 2,147,483,647.
- 32_BIT_FLOAT —A 32-bit data type supporting decimals.
- 64_BIT —A 64-bit data type supporting decimals.
3. change "NoData Value" /修改NoData值！！更改的是NoData Value（NoData像素的标识值），而不是把NoData改为某个有效的Pixel value。
