IBasicGeoprocessor Interface

Provides access to members that control the basic geoprocessor.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

IBasicGeoprocessor provides access to the methods and properties of the BasicGeoprocessor object. The functionality of the BasicGeoprocessor object had been superseded by the new Geoprocessing framework of ArcGIS starting at version 9.0. Developers should utilize the new tools whenever possible.

Members

Classes that implement IBasicGeoprocessor

Classes	Description
BasicGeoprocessor	A basic geoprocessor.

Remarks

Dissolve aggregates features of an input layer based on values of a specified attribute; and can be used to create either a new layer or a stand alone summary table.

Merge combines layers of the same geometry type into a single feature class.

Clip extracts features of a point, line, or polygon layer based on the spatial extent of an overlay polygon layer. The attributes of the input feature class are carried over to the output feature class.

Intersect clips the features of a line or polygon layer with features of an overlay polygon layer. The output feature class will have the attributes of both input and overlay layers.

Union combines the features of two polygon layers into a new feature class that contains the attributes and the full spatial extent of both layers.

IBasicGeoprocessor.SpatialReference should be set to an appropriate to high or low precision based on the target workspace. For more details see the SpatialReference documentation, especially the ISpatialReferenceResolution interface.
