Polygon Digitizer Help
This extension extends the capability of ArcView’s polygon digitizing. The capabilities include:

  • The ability to enter attribute values during digitizing.
  • The ability to allow the user to select which fields in the theme values will be entered.
  • Automatic creation of a unique ID for each record.
  • The incorporation of logic so that adjacent polygons, islands and discrete polygons can be digitized using the same button. This helps avoid overlaps and slivers in the polygon data.

Note: This extension has only been tested with ArcView 3.1 and 3.2 running on Windows 95/98 and Windows NT operating systems.

Loading the extension onto your computer
Using Windows Explorer, copy the PolygonTool.avx file into the /Esri/Av_gis30/Arcview/Ext32 folder. Typically this folder is on the C: drive.

Loading the extension into ArcView
In ArcView, select the "File" menu item in the project window and click the "Extensions" option. A dialog box showing a list of available extensions are shown. Check the "B.I.T.S. Polygon Tool" extension and then press the "OK" button.

Using the extension
In the View window, a "Polygon Tool" menu item should have appeared. Select the "Start Polygon Tool" option to start the application. The following dialog box should appear.

Every button on the application should be grayed except for the Help button. Create a new polygon theme or load a polygon theme into the view. Make the theme editable. The application should now look like this:

 

Entering data as you digitize
If you want to enter data as you digitize, push the "select fields" button. A list of available fields in the shape file will appear. Select the fields that data will be entered in and press OK. Before you start digitizing, make sure that the "Add values to selected fields" radio button is selected.

Note: If the "Add values to selected fields" radio button is picked and there are no fields in the shapefile the application will return an error. Also note that there are certain field names that cannot be populated by this application. These field names are:

1. shape
2. ID
3. Area
4. Perimeter
5. Date
6. Xcoor
7. YCoor
8. Poly_ID

This version of Polygon Tools does not support the input of data into date fields other than the date field described below.

Automated population of attributes
If either the "Add values to default fields" or the "Add values to selected fields" radio buttons are selected, three fields will be created and populated automatically. These fields are:

1. Poly_id
2. Area
3. Date

The POLY_ID field is populated with a unique ID number for the record. The number is determined by determining the largest number currently used in the field and adding one to that value. A minimum number of 100 is used.

The AREA field is populated with the area of the polygon in the map units of the view. Note that the area is calculated after each polygon is digitized. If the polygon is changed, the area field is not updated.

The DATE is the current date (the date the polygon was digitized).

Select the "Add no field values" if you do not wish any fields to be populated.

Digitizing Polygons
To start digitizing, press the "BARR" button. This will start the digitizing tool (similar to pressing the "Draw Polygon" button on the button bar). Start digitizing the polygons. Double click on the last point to complete the polygon. The application will determine if the polygon should be snapped to an adjacent polygon, is an island within existing polygons, or is not connected to any other polygons (a discrete polygon). The application uses most of the same logic as ArcView’s polygon tools (polygon draw and draw line to append polygon). The exception is that this application will create true islands. You do not have to use the "Subtract Features" option in the edit menu.

If you need to undo an edit, just press the "Undo Change" button. You may have to press the button several times if you are manually or automatically entering attribute values to the theme’s table.

If used correctly, this application will create a theme that should not have any slivers or polygon overlaps. However, there may be some cases where overlaps and slivers may occur. It is highly recommended that the theme be inspected for such occurrences.

New Features in Version 1.1
Automatic Panning—f you wish to have the application pan automatically, select the Automatic Panning checkbox. As the mouse approaches the edge of the view display, the view will automatically be recentered to allow for uninterupted digitizing.

Color and Width of Digitizing Line—The color and width of the line created when digitizing can be modified by selecting values from the Color and Line Width drop down lists. These values can be changed at any time, even while digitizing a polygon.


 Layout Table Wizard Help

This extension creates a button on your layout tool bar and works similar to the legend wizard that is included in ArcView 3.1.

Note: This extension has only been tested with ArcView 3.1 and 3.2 running on Windows 95/98 and Windows NT operating systems.

Loading the extension onto your computer
Using windows explorer, copy the TableWizard.avx file onto the /Esri/Av_gis30/Arcview/Ext32 folder. Typically this folder is on the C: drive.

Loading the extension into ArcView
 In ArcView, select the "File" menu item in the project window and click the "Extensions" option. A dialog box showing a list of available extensions are shown. Check the "B.I.T.S. Layout Table Wizard" extension and then press the "OK" button.

How to Run Table Wizard
After loading the TABLE WIZARD in your project, select the "TABLE WIZARD" tool button and then click your mouse on the layout where you want the table placed. A dialog box appears that will give you a list of current tables in your project. Select the table from the list. The application provides options to select what fields you want to display, what field you want to sort by, the font size, and the order you want to display the selected fields.

Note: You must have a selection set made before the table will be placed in the layout. You can query the table from the dialog box by using the query tools shown.

Caution: This application creates a graphic that does not have a dynamic link to the table. You must recreate the table graphic in the layout if you want to display changes made in the table.
