Extract Tool in Arcgis
The Extract tools let you select features and attributes in a feature class or table based on a query or spatial extraction. The output features and attributes are stored in a feature class or table.
There are four types of extraction tools available in ArcGIS;
ArcGIS Extract Tools
Extracts input features that overlay the clip features.
Use this tool to cut out a piece of one feature class using one or more of the features in another feature class as a cookie cutter. This is particularly useful for creating a new feature class—also referred to as study area or area of interest (AOI)—that contains a geographic subset of the features in another, larger feature class.
Extracts features from an input feature class or input feature layer, typically using a select or SQL (Structured Query Language) expression and stores them in an output feature class.
Splitting the Input Features creates a subset of multiple output feature classes.The Split Field’s unique values form the names of the output feature classes.
Selects table records matching a SQL expression and writes them to an output table.
ArcGIS Extraction Tools
The Extraction tools allow you to extract a subset of cells from a raster by either the cells attributes or their spatial location. You can also obtain the cell values for specific locations as an attribute in a point feature class or as a table.
The following table lists the available Extraction tools;
|Extract by Attributes||Extracts the cells of a raster based on a logical query.|
|Extract by Circle||Extracts the cells of a raster based on a circle.|
|Extract by Mask||Extracts the cells of a raster that correspond to the areas defined by a mask.|
|Extract by Points||Extracts the cells of a raster based on a set of coordinate points.|
|Extract by Polygon||Extracts the cells of a raster based on a polygon.|
|Extract by Rectangle||Extracts the cells of a raster based on a rectangle.|
|Extract Multi Values to Points||Extracts cell values at locations specified in a point feature class from one or more rasters.|
|Extract Values to Points||Extracts the cell values of a raster based on a set of point features.|
|Sample||Creates a table that shows the values of cells from a raster, or set of rasters.|
