BaseOps User's Guide, Chapter 4: Introduction to Cases

A BaseOps case is a collection of all information associated with a Noisemap noise analysis. A case includes...

Cases are stored in files that have the extension .baseops. BaseOps is a tool for editing these case files. As you work with its various user interface components (the list pane, the case options dialog box, etc.), you edit the case that is currently open. This is analogous to using Microsoft Word to edit a .doc document file.

This chapter discusses the basics of creating and editing cases. Later chapters discuss the various elements of a case in detail.

Creating a New Case

To create a new case, follow these steps.

  1. Choose New from the File menu. The standard Windows dialog box for selecting a file name is displayed. Familiarity with the use of this dialog box is assumed.

  2. Navigate to the directory where you want your case file to be created. Type the name of the file that will contain the new case. Then press Save.

  3. A new, empty case appears in the BaseOps window.

Opening an Existing Case

To open an existing case, follow these steps.

  1. Choose Open from the File menu. The standard Windows dialog box for opening files is displayed. Familiarity with the use of this dialog box is assumed.

  2. Navigate to the directory where your case file is located, then open the file. Case files typically have the extension .baseops.

  3. The case appears in the BaseOps window.

Note:

BaseOps can also open other types of files: .bps (old-style BaseOps files); .ops and .opx (NMap/AAM/RNM input files); .inp (old-style MRNMap input files); and .ins and .inx (MRNMap input files). If one of these types of files is opened, a .baseops case file containing the imported data will automatically be created.

Saving a Case

BaseOps has no explicit save command. Cases are automatically saved at key moments (when BaseOps is shut down, when a new case is opened, etc.). In addition, BaseOps periodically saves your case as you work, so that even if your computer should crash, you will lose, at most, a couple of minutes of work.

Renaming a Case

To rename a case file, following these steps.

  1. Choose Save As from the File menu. The standard Windows dialog box for selecting a file name is displayed. Familiarity with the use of this dialog box is assumed.

  2. Navigate to the directory where you want your renamed case file to be located. Type the new name of the case file. Then press Save.

Alternatively, you can use Windows Explorer or My Computer to move and/or rename the .baseops case file.

Editing Case Data

Case data consists of all information used as input into the noise models: runways, flight tracks, weather information, etc. Case data is viewed and edited using the three panes (the list, text, and map panes) of the BaseOps main window. For more information, see A Brief Tour of BaseOps; Working with the List Pane; and Working with the Map Pane.

Editing Case Options

Case options control how BaseOps presents information to you. Examples of case options include the units used for entering distances and the color of flight tracks when they are drawn on a map.

Use the Case Options dialog box to view and edit case options. To display the Case Options dialog box, you can:

The left portion of the dialog box displays a list of option categories. One category in this list is always selected. The right portion of the dialog box displays controls that allow you to change the options in the selected category.

The Case Options dialog box is a Multiple Page dialog box. See Multiple Page Dialog Boxes for more information.

Editing an Object's Options

Many of the objects (runways, flight tracks, flight profiles, etc.) that make up a BaseOps case have options that you can edit. To edit the selected object's options, you can:

The Object Options dialog box is displayed.

The left portion of the dialog box displays a list of option categories. One category in this list is always selected. The right portion of the dialog box displays controls that allow you to change the options in the selected category.

The Object Options dialog box is a Multiple Page dialog box. See Multiple Page Dialog Boxes for more information.

Setting the Case Coordinate System

The case coordinate system is used by BaseOps to specify geographic locations. This is the coordinate system used to enter the location of objects such as runways and navigational aids, and to display locations in reports and on the status bar.

Use the Coordinate System page of the Case Options dialog box to set the case coordinate system.

Select the coordinate system. You have two options.

Tip:

You can change the case coordinate system at any time. Any previously entered locations will be displayed in the new coordinate system.

Setting the Case's Physical Units

The case's physical units are used by BaseOps to specify distances, temperatures, etc. These are the units used to enter object properties such as runway widths, and to display values in reports and on the status bar.

Use the Units page of the Case Options dialog box to set the case units.

For each measurement category, select the desired units. The following categories are available.

Tip:

You can change a case's physical units at any time. Any previously entered values will be displayed in the new units.

Using Undo and Redo

BaseOps has an undo feature that allows you to reverse any changes you have made to a BaseOps case. This feature is similar to the undo feature found in most word processors --- each time you choose undo, the BaseOps case is restored to the state it was in before the most recent edit.

To undo an edit, you can:

To redo a previously undone edit, you can:

Note:

You can disable the undo system if the amount of memory it uses becomes problematic. You should need to do this only in rare circumstances, such as when you are using a computer with very limited memory.

To disable the undo system, choose Application Options from the Tools menu, go to the Undo System page of the BaseOps Application Options dialog box, then uncheck the Undo system enabled box.
