ArcView Task Manager: Key Features and Usage

Posted on Jan 8, 2025 in Computers

1. Components of the ArcView Task Manager

The ArcView Task Manager comprises several essential components:

  • View: Used for creating and opening maps.
  • Table: Functions as a database, allowing the creation or opening of databases.
  • Chart: Enables the creation of graphics.
  • Layout: Provides a print preview.
  • Script: Facilitates programming using Avenue.

2. File Types Supported by ArcView Project Manager

The ArcView Project Manager can open various file types, including:

  • .SHP
  • .SHX
  • .DWF
  • .APR
  • .DBF

3. Transporting .APR Files to Another Computer

When transporting an .APR file to another computer, it’s crucial to maintain the directory structure of the developed project.

4. Purpose of the File/Extensions Command

The File/Extensions command enables or disables the system’s capabilities to access different external file formats.

5. Elements of an ArcView Window

An ArcView window typically displays the following elements:

  • Left side: Subjects and their keys.
  • Center: The map itself.
  • Top: The corresponding toolbar for working within the view.

6. Adding and Positioning a New Theme in a View

To add a new theme and make it visible in the background:

  1. Add the theme using either the Add Theme icon or View > Add Theme.
  2. Check the theme’s checkbox.
  3. Drag the theme to the bottom of the list of themes.

7. Structuring an SQL Query for Income Range Exclusion

Given a field named “INCOME”, where value X is less than Y, to select all records not included between X and Y, use the following SQL query:

((INCOME) <= X) OR ((INCOME) >= Y)

8. Case Sensitivity in the FIND Command

The FIND command is not case-sensitive. You can enter the search term in either uppercase or lowercase.

9. Function and Activation of the PROMOTE Icon

The PROMOTE icon, used with tables, allows you to visually move selected records to the top of the table. To activate it, you must first select the desired data.

10. Considerations Before Performing Buffer Operations

Before performing an area of influence (buffer) operation, ensure that the working units are properly enabled.

11. Modifying Incorrect Values in a Database

To modify an incorrect value in a database:

  1. Open the database.
  2. Start editing the table.
  3. Make the necessary modifications.
  4. Stop editing the table.

12. Resolving Theme Overlap in a View

When adding a polygon theme to a view with existing line and point themes, the new theme may overlap and obscure the others. To resolve this:

  1. Activate the polygon theme.
  2. Drag it to the bottom of the content list.

This will allow all themes to be visible.

13. Linking vs. Joining Tables

Tables should be linked instead of joined when there is a one-to-many relationship between records.

14. Isolating a Specific Basin from a Regional Map

To isolate a specific basin from a regional map containing watershed divisions:

  1. Identify the basin.
  2. Select the basin.
  3. Convert the selected basin to a new theme, assigning it a desired name.

15. Requirements for Geocoding by Address

To perform geocoding by address, you need:

  1. Structured Arcs: Main roads structured as arcs, with their length and direction (left and right) at the start and end of each arc.
  2. Event Data: A field containing the geocoding address structure, corresponding to the file format set up for the axes.
