Convert floating point raster to integer
WebSep 7, 2011 · Whenever possible, it is recommended to convert floating-point rasters to integer with the Int function. The following environment settings affect this tool: General: Current Workspace, Scratch Workspace, Output Coordinate system, Output Extent, Snap Raster. Raster Analysis: Cell size, Mask. WebOpen the raster, and in the Transform pane choose Copy. Choose int32 (or whatever other integer type you want) from the drop down list for Channel type. Enter a name for your new raster, and press Transform. Done. The default setting for Transforms is to use all CPU cores and all GPU cores, so it's fast with big rasters.

WebJun 4, 2013 · The first step is described as follows: "1.) Zpixel = Elevation of a pixel. Convert DEM pixels to points. VALUE field in attribute table contains elevations". I'm not sure which tool to use to achieve this conversion. The DEM of my watershed is a 32 bit floating point GRID raster. I tried the Spatial Analyst Tool, Extract Values to Points ... WebWith functions of type * (see table above), the result is float if any argument is float, integer otherwise. However, GRASS raster map layers can only store integer values. If the final value of the expression is a floating point value, this value is rounded to the nearest integer before storing it in the result raster map layer. Note that ...

WebConvert 1 bit data to 8 bit. (Optional) Specifies whether the input 1-bit raster dataset will be converted to an 8-bit raster dataset. In this conversion, the value 1 in the input raster dataset will be changed to 255 in the output raster dataset. This is useful when importing a 1-bit raster dataset to a geodatabase. WebUse 1 integer bit as the maximum value required for any Lanczos coefficient is 1.0; Use between 6 and 8 fraction bits. Typically, the filter coefficients produce noninteger floating-point values. To convert each floating-point coefficient into its closest quantized representation in the selected fixed-point format:
