Extract Values To Table (Geostatistical Analyst)

Available with Geostatistical Analyst license.


Extracts cell values from a set of rasters to a table, based on a point or polygon feature class.


  • This tool is primarily designed to analyze the output from the Gaussian Geostatistical Simulations tool.

  • All the rasters must have the same spatial reference and cell size.

  • If a point feature class is used, the output table has a record for each point and each raster that has data. Polygonal data will be treated as point data. The cell center of the input rasters will determine the number of points and will also be used to decide whether the cell is contained within the polygon or not.

  • Values outside the raster's extent will be ignored.

  • Multipart feature classes are not supported.

  • In the case of coincident points, the last one encountered will be used and the rest will be ignored. In the same vane, if overlapping polygons are encountered only one of the intersected features will be processed.

  • If Spatial Analyst is available, the Sample tool can also be used. However, the output table needs to be transposed if the values are to be graphed.


ExtractValuesToTable(in_features, in_rasters, out_table, {out_raster_names_table}, {add_warning_field})
ParameterExplanationData Type

The points or polygon features to be created.

Feature Layer

The rasters must all have the same extent, coordinate system, and cell size.

Raster Layer; Mosaic Layer

The output table contains a record for each point and each raster that has data. If polygon features are input, they are converted to points that coincide with the raster cell centers.


Saves the names of the Input rasters to disc.


Records if input features are partially or completely covered by the Input rasters.

  • ADD_WARNING_FIELDWarning field is added to the output table and populated with a P when a feature is partially covered by raster values.
  • DO_NOT_ADD_WARNING_FIELDWarning field is not added to the output table.

Code sample

ExtractValuesToTable example 1 (Python window)

Extract the cell values from a raster to a table, based on a point feature class.

import arcpy
from arcpy import env
env.workspace = "C:/gapyexamples/data"
                              "C:/gapyexamples/output/outEVFR.dbf", "", "")
ExtractValuesToTable example 2 (stand-alone script)

Extract the cell values from a raster to a table, based on a point feature class.

# Name: ExtractValuesToTable_Example_02.py
# Description: Extract the cell values from a raster, based on 
#              a point feature class, to a table.
# Requirements: Geostatistical Analyst Extension

# Import system modules
import arcpy
from arcpy import env

# Set environment settings
env.workspace = "C:/gapyexamples/data"

# Set local variables
inPoints = "C:/gapyexamples/data/ca_ozone_pts.shp"
raster = "C:/gapyexamples/data/inraster"
outTable = "C:/gapyexamples/output/outEVFR.dbf"

# Execute ExtractValuesToTable
arcpy.ExtractValuesToTable_ga(inPoints, raster, outTable, "", "")
