This tool creates a table or a point feature class that shows the values of cells from a raster, or set of rasters, for defined locations. The locations are defined by raster cells, polygon features, polyline features, or by a set of points.
Some example applications of this tool include the following:
If Use current map extent is checked, variables or bands of the layer that are visible within the current map extent will be analyzed. If unchecked, variables or bands of the full layer will be analyzed, even if they are outside the current map extent.
A single image or a list of images whose values will be sampled based on the input location data.
To sample all slices from a multidimensional imagery layer, it must be the only input raster.
Data identifying positions you want to sample.
The input location data can be a raster, or a point, polyline, or polygon feature class.
A field containing a different value for every location or feature in the input location raster or feature class.
Specify the time, depth, or other acquisition data associated with the location cells or features.
For each dimension, there are three options of specifying the acquisition information associated with location cells or features:
This parameter is only available when the Choose imagery layer(s) to sample parameter is a multidimensional raster.
The specified distance around the location data features. The buffer distance is specified in the linear units of the location feature's spatial reference. If the feature uses a geographic reference, the unit will be degrees.
Statistics will be calculated within this buffer area.
This parameter is only available when the Choose imagery layer(s) to sample is a multidimensional raster.
The type of statistic to be calculated.
This parameter is only available when the Choose imagery layer(s) to sample parameter is a multidimensional raster, and the Choose location layer parameters are polylines or polygons, or Specify buffer distance field or value (Optional) is specified.
This value can range from 0 to 100. The default is 90.
This parameter is only available when the Choose statistics Type parameter is set to Percentile.
Resampling algorithm used when sampling a raster.
Specifies whether sampled values appear in rows or columns in the output table.
This parameter is only available when the Choose imagery layer(s) to sample parameter is a multidimensional raster and contains one variable and one dimension, and each slice is a single-band raster.
Specifies whether to generate a point feature class with sampled values in its table, or only a table with sampled values.
The name of the layer that will be created in My Content and added to the map. The default name is based on the tool name and the input layer name. If the layer already exists, you will be prompted to provide another name.
You can specify the name of a folder in My Content where the result will be saved using the Save result in drop-down box.
