Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Spatial Analyst Extension.

Remarks

pointDataset

an input point featureclass or feature class descriptor containing the points of interests to identify cell values from the input raster.

valueRaster

an input Raster, RasterDataset, RasterBand, or RasterDescriptor.

The geoDataset contains the cell values which determine the output RASTERVALU attribute of the output point geoDataset.

[interpolateValues]

a boolean specifying if the value of the RASTERVALU attribute will be interpolated between neighboring cells or given the value of the cell in which it is found to occur.

If TRUE, then the attribute value will be determined by the bilinear interpolation method.

If FALSE, then the attribute value will be determined by the cell value from the input raster. This is the default option.

[allAttributes]

a boolean specifying if the all attributes from the input value raster are to be included in the output geoDatatset.

If TRUE, all attributes of the input raster are included in the output.

If FALSE, attributes from the input raster are not included. This is the default option.
