BaseOps User's Guide, Chapter 2: Getting Started

Minimum System Requirements

To take full advantage of BaseOps, your computer should meet the following minimum requirements.

Obtaining BaseOps

Visit the BaseOps web page, http://wasmerconsulting.com/baseops.htm, and download Noisemap, which will contain the latest version of BaseOps.

If desired, you can subscribe to the mailing list, and be notified by e-mail when new versions of BaseOps are released. See the BaseOps web page for additional information.

Installing Noisemap

BaseOps is distributed as part of Noisemap. The Noisemap installation routine will install the latest versions of BaseOps, NMap, MRNMap, Noisefile, Omega10, Omega11, and NMPlot.

Noisemap is distributed as a self-extracting WinZip file. Installation consists of nothing more than uncompressing the Noisemap files and copying them onto your hard drive. To install Noisemap, follow these steps.

  1. Go the the BaseOps web site, http://wasmerconsulting.com/baseops.htm, and click on the Download Noisemap link. A file named install_noisemap.exe will be transferred to your computer.

  2. From Windows Explorer or My Computer, find the file install_noisemap.exe and double-click on it. The Installing Noisemap dialog box appears.

  3. In the Unzip To Folder text box, type the name of the directory where you wish to install Noisemap. Press the Browse button to display the Browse for Folder dialog box, which allows you to select an existing directory.

    The various components of Noisemap (BaseOps, NMap, NMPlot, etc.) will be installed in subdirectories of the Noisemap directory.

  4. Press the Unzip button. The Noisemap files are copied to your hard disk. Noisemap is now installed.

  5. The file install_noisemap.exe is no longer needed. Delete it if you wish.

Installing the Optional AAM Model

The Advanced Acoustic Model (AAM) is not included with the standard Noisemap installation package. If you wish to perform a noise analysis using AAM aircraft, you must first install AAM.

To install AAM, run the AAM installer, and choose to install AAM into the Noisemap\AAM directory. After a successful installation, the Noisemap\AAM directory will have new subdirectories, including Noisemap\AAM\bin (which will contain the AAM executable) and Noisemap\AAM\ncfiles (which will contain the AAM noise sphere files).


If you've been using previous versions of AAM with BaseOps, note the change in where the AAM files are located. Previously, everything was located in the Noisemap\AAM directory. Now, some files are located in subdirectories, as described above. You can delete the old aam.exe and netcdf.dll files from the Noisemap\AAM directory, and move your .nc noise sphere files to the Noisemap\AAM\ncfiles subdirectory.

After installing AAM, read the file "Noisemap\AAM\Default AAM Aircraft.txt" for instructions on registering AAM aircraft with BaseOps.

As of January 2017, the point of contact for obtaining AAM was:

Juliet Page
Volpe National Transportation Systems Center
U.S. Department of Transportation

Installing the Optional RNM Model


RNM is being replaced by the AAM. If you are starting a new project, it is recommended that you use AAM. RNM is still being supported primarily for existing legacy noise cases.

The Rotorcraft Noise Model (RNM) is not included with the standard Noisemap installation package. If you wish to perform a noise analysis using RNM aircraft, you must first install RNM. Simply follow the installation instructions included with the RNM distribution package, noting these points:

As of August 2003, the point of contact for obtaining RNM was:

David A. Conner
NASA Langley Research Center
e-mail: d.a.conner@larc.nasa.gov

Upgrading to a Later Version of Noisemap

To upgrade to a later version of Noisemap, simply perform a normal installation, noting these points.

All BaseOps configuration information is stored in the file BaseOps.cfg. This file will not be overwritten when you install later versions of Noisemap. Therefore, your configuration will be preserved.

Uninstalling Noisemap

The Noisemap installer does not make any hidden changes to your computer. In particular, it does not install any files in the Windows or System directories, and does not modify the registry. To uninstall Noisemap, simply use Windows Explorer or My Computer to delete the directory where Noisemap is installed.

Starting BaseOps

To start BaseOps, follow these steps.

  1. Using Windows Explorer or My Computer, navigate to the folder where BaseOps is installed.

  2. Double-click on the BaseOps icon, , labeled BaseOps.exe.

Getting Help

Press the F1 key at any time to access BaseOps's extensive online help system. Press Ctrl + F1 to display the BaseOps User's Guide table of contents. Accessing Help discusses the help system in detail.
