ArcView Extensions

This page is meant to be a place where the GIS professionals can find ArcView extensions that will help her/him to be more proficient in their craft. We hope you find the extensions here to be helpful in many ways. They are generally well written and are meant to be good examples. The extensions are here for your use and dissemination to others. If you would like the Project file (apr) that created the extension, please e-mail Keith Massie. The extensions were zipped using PKZIP.

Special thanks to Alan Holsted of Metro (Portland, Oregon). He wrote some of the extensions listed below.

• Field Definitions
  This extension adds an option to the bottom of the Table Menu, called "Field Definitions". When selected, field definitions for all fields in the active table are displayed in a Message Box. This is a handy way to find out the type and length of fields in a table. ( fielddef.zip 2K )


• Convert Polygons or Polylines to Points
  This extension converts each vertex in a polygon or polyline theme to a point. You can select to have a new point theme created, or just point graphics. If a point theme is selected, then you have the option of retaining the attributes. You can also select the points symbol (circle, triangle, or square), color, and size. ( vertex.zip 3K )
• Print a View
  The Print a View extension adds a print icon to the button bar (first row of icons) at the far right. This button automates the process of printing a view from ArcView. The extension takes the current view, counts the number of themes with complex legends (basically classified data), and creates a layout. The user does not need to know how to use Layouts, because the extension automates the entire map printing process.
  Two titles and two subtitles can be added, plus the map can be printed in one of four sizes. There is the opportunity to set the scale during the map printing process. ( printmap.zip 8K )

Other Recommended Extensions

• Xtools This extension contains useful tools developed, collected, or modified by Mike DeLaune, Oregon Department of Forestry. All of the more complicated tools have "Shift" click instructions. That is, you hold down the shift key and click on the menu item to get a description of the tool and instructions for running it. For Windows users, the description and instructions are copied to the system clipboard, so you can paste them into a text editor like Notepad or Word and thus print them out. Xtools is a user-developed extension aimed at meeting the analytic needs of ArcView users in the Oregon Department of Forestry. It is being made available to others with similar needs free of charge on an "as is" basis.
• Projector_ol (Oregon Lambert) Also created by Mike DeLaune, Oregon Department of Forestry. This extension allows the user to project a selected feature theme to a new shape file with spatial locations in any projection that ArcView supports. This extension is based on the Projector! extension provided by ESRI as a sample extension. It is provided as a new extension with the following enhancements:
  1.The Projector_ol extension creates a custom Oregon Lambert projection and adds it to the list of standard projections, with the permission of the user.
  2.The Projector_ol gives the user the ability to convert between Survey Feet (the ArcView standard) and International Feet, the Oregon Lambert standard. The conversion may be done either along with a projection change, or independently. Separate buttons are provided for these two options.
• Convert ArcView Shapefiles to CAD This extension was developed by Guthrie CAD/GIS of Adelaide, South Austrialia. Paul Guthrie wrote the program, and a free download is available. The product, Arcv2CAD is a stand-alone application that lets you convert ArcView / ESRI Shape files to AutoCAD DXF and DWG formats. This allows Shapefiles to be read by virtually all CAD software (eg AutoCAD, CADKey, QikDraw, MicroStation, AutoSketch, FelixCAD), as well as many other Mapping, Drawing and Graphics programs (e.g., CorelDraw).
• Analysis Extension
  This extension was developed by Mikael Elmquist of SWEGIS in Karlstad, Sweden. There is a free download available.
• Extensions Included with ArcView
  This page, maintained by the Silicon Valley ArcView Users Group, has an excellent listing of all the extensions that are provided with ArcView. These extensions are installed with ArcView or are provided as sample extensions in the samples subdirectory.
