The values stored in raster data pixels can be divided into integer and floating-point types. Plastic type and floating-point type each have their own bit depth, indicating the range of this pixel value, and signed type and unsigned type indicate whether their values can remain negative.

The most common is 8bit.

Unsigned

Integer in the range of 0-255. Pay attention to the setting of related options when using polygon to raster. If the result is not set well, it will be a color in arcmap, because for the range, the actual cell values are all gathered together, and the default rendering method is stretching, which is the effect.

For the attribute table, the generated plastic grid may have an attribute table, with one condition, which I don't remember clearly. You can view the help document, similar to the value range.

Table, that's probably the name.

In addition, the newly generated raster usually creates statistics automatically, which will affect its rendering effect in arcmap. If you have not created statistics, it is recommended to create them yourself.
