Extract by Attributes

Summary

Extract raster pixels based on logical queries. If the input raster has a DBF attribute table, you can query by attribute fields or pixel values, and the output result will not include an attribute table; if there is no attribute table, you can query by pixel values.

Usage

ClickData Management> Raster Tools > Extract by Attributes

Settings

• Select File:：Select raster file. Common formats such as tif, tiff, dat, and img are supported.
• Where Clause：Use SQL query statements. If the evaluation result of the query is True, the pixel value at that position will be set to the corresponding pixel value in the input raster. If the evaluation result is False, the pixel value at that position will be assigned NoData; if the input raster has no NoData, it will be filled with 0. You can combine queries by adding conditions.
• Output Path: Output Path: The result output folder path. After execution, the clipped raster will be output, supporting tif, tiff, and img formats.
