Wasmer Consulting NMPlot User's Guide Setting NMPlot Application Options
Application options allow you to customize NMPlot.
Most application options are set using the NMPlot Application Options dialog box. To change these options, follow these steps.
Choose Application Options from the Options menu. The NMPlot Application Options dialog box appears.
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. Select the desired category by clicking on it.
The Application Options dialog box is a Multiple Page dialog box. See Multiple Page Dialog Boxes for more information.
Change the options as desired, then press OK.
Use the Default Datum page of the NMPlot Application Options dialog box to set the default datum.
If the majority of the geographic data that you work with is in a single datum, choose it as the default. Otherwise, set the default to WGS-84.
NMPlot will assume that all geographic data is in the default datum unless you specify otherwise. You will be able to override the default datum where necessary.
The cache is a portion of your computer's memory and hard disk that is used to store data for reuse. Typically, this data is either the result of a time-consuming calculation, or else is downloaded over a (relatively) slow internet connection. The cache is a performance optimization - if the data is needed again in the future, it can be quickly retrieved from the cache.
The files in the disk cache can be deleted at any time, with no effect on the application other than the performance penalty of having to recalculate or redownload the data when it is needed in the future.
Use the Cache Options page of the NMPlot Application Options dialog box to manage the cache.
Maximum memory cache size: Enter the maximum amount of your computer's memory, in megabytes, that the cache will use. Increasing the memory cache size can result in greater performance. But it also decreases the amount of memory available for data that does not reside in the cache. If you are experiencing out-of-memory errors from NMPlot, try decreasing the memory cache size.
Disk cache root directory: Enter the directory where disk cache files will be stored. As the disk cache can grow quite large, you may want to place the cache root on a drive with plenty of free space.
Show Cache Information: Pressing this button will display the number of items and the total summed size of both the memory and disk caches.
Empty Disk Cache: Pressing this button will delete all files in the disk cache. Normally, you would not need to do this. Each disk cache file has an expiration date, after which the file is automatically deleted, so the cache will not grow without limit. But it is possible for it to grow quite large. If disk space is low, you may need to manually empty the cache.
Use the Physical Units page of the NMPlot Application Options dialog box to set the units of measurement NMPlot uses to display information.
You can select the units used for:
Distance - The Distance units are used to display the distance between two points when using the Measurement tool.
Graphical Map Scale - These units are used when drawing a graphical map scale on a map. For example, if you select "1 inch = XXX feet" for the units, then the graphical map scale will look similar to the following example.
Use the Mouse Location Display Coordinates page of the NMPlot Application Options dialog box to set the geographic coordinate system NMPlot uses to display the location of the mouse on the status bar.
Select whether to use the coordinate system of a plot's primary grid, or to specify a global coordinate system used for all plots. If you select a global coordinate system, set the system's options. See Coordinate System Control for more information on setting coordinate system options.
Use the Client-Specific Extensions page of the NMPlot Application Options dialog box to configure any extensions installed in your version of NMPlot. Client-specific extensions give NMPlot additional capabilities when working with grids created by specific third-party sources.
The Client-Specific Extensions page lists all installed extensions. Press the Information button to learn more about an extension. Press the Properties button to change an extension's options.
NOISEMAP is a suite of computer programs used to calculate the noise impacts of aircraft operations. It consists of several noise models (NMap, AAM, RNM, and MRNMap), BaseOps (a GUI application used for entering data and running the noise models), and NMPlot (used for displaying the results of the noise models).
The NOISEMAP extension to NMPlot lets you interactively run the NOISEMAP models from within NMPlot. Both grid and point-of-interest calculations can be performed. The extension also allows NMPlot to read NOISEMAP Point-Of-Interest (POI) files.
In order to use the NOISEMAP extension to NMPlot, you must have NOISEMAP installed on your computer. In addition, the primary grid of the plot you are working with must have been created by using BaseOps to run the NMap, MRNMap, and/or AAM noise models. Note that currently, the NOISEMAP extension does not support the RNM noise model. The extension does, however, support combined NMap/MRNMap/AAM noise grids (i.e., noise grids created from BaseOps cases that contain a combination of NMap, MRNMap, and AAM operations).
To configure the NOISEMAP extension, follow these steps.
Choose Application Options from the Options menu. The Application Options dialog box appears.
Select the Extensions page.
Press the Properties button associated with the NOISEMAP extension. The NOISEMAP Extension Options dialog box appears.
Type the name and location of the NMap, MRNMap, and AAM noise models (i.e., the .exe files). These programs will typically have the names nmap.exe, mrnmap.exe, and aam.exe. Press the Browse button , located to the right of the text box, to display the Open File dialog box, which allows you to browse for a file.
You can use NMPlot's Point of Interest Computation tool to perform a NOISEMAP point of interest analysis from within NMPlot. See The Point Of Interest Computation Mouse Tool for information on using this tool.
After performing the analysis, NMPlot will display the results, including the ranked flight and static event tables.
You can use NMPlot's Grid Computation tool to perform a NOISEMAP grid calculation from within NMPlot. Typically, you will use this feature to enhance the grid resolution around areas of high noise gradients (for example, near runways and static pads). See The Grid Computation Mouse Tool for information on using the Grid Computation tool.
When NMPlot opens a grid file created by NOISEMAP, it looks for a Point-Of-Interest file that has the same name as the grid file, but with the extension .poi. If a POI file is found, it will be read along with the grid file.
If you display a plot of a NOISEMAP grid, and choose to display points of interest, you can click on a point using the Display Properties mouse tool and display a full report on that point, including the ranked flight and static event tables.
To set the options of new plots created with the New command on the File menu, follow these steps.
Display the Plot Options dialog box, and set the options as desired.
Choose Save As from the File menu. The Save As dialog box is displayed.
Navigate to the directory where you installed NMPlot: i.e., the directory where NMPlot.exe is located. Save the plot in this directory with the name Default.nmp.
In the future, when you create a new plot, it will have the same options as Default.nmp. For example, if the background color of the plot in Default.nmp is blue, then all new plots will have a blue background.
