Clip_Shapefile_By_Envelope

Description:

This sample purpose is to show pure ArcGIS Engine developers how to accomplish basic geoprocessing tasks using ITopologicalOperator. Applications like this are suitable for batch driven processing. The application takes a source shapefile and the extents of a clipping envelope. These are used to export the features inside the clipping envelope to a newly created shapefile.
Products:

Engine: C++, Java

Platforms: Windows, Solaris, Linux

Minimum ArcGIS Release: 9.0

How to use:
  1. Run the application.
  2. A new shapefile of the clip will be created.
[C++]

C++ Specific Notes

  1. Run the application with valid data for the following parameters:
    • input shapefile
    • outut shapefile
  2. Parameters for the envelope have been hardcoded. To use a different envelope, edit the following lines from the top of ClipShapefileByEnv.cpp: 

      double xMin = -130.0;

      double xMax = -114.0;

      double yMin = 31.0;

      double yMax = 41.5;

Java Specific Notes

  1. In the sample.properties file, uncomment the following arguments and add locations local to your system:
    • input.data.path : Path to input shapefile
    • output.data.path : Path to resulting shapefile
    • xmin : xmin value for clip envelope
    • ymin : ymin value for clip envelope
    • xmax : xmax value for clip envelope
    • ymax : ymax value for clip envelope
