Wasmer Consulting BaseOps User's Guide Importing Integrated Noise Model (INM) Cases
The United States' Federal Aviation Administration's Integrated Noise Model (INM) is commonly used to calculate the noise levels around civilian airports. BaseOps can import some information from INM cases.
There are a number of differences between the ways that Noisemap/BaseOps and INM represent noise cases. For example, some INM flight tracks are point-to-point tracks (p-tracks), while all Noisemap flight tracks are represented using vectors.
Because of these differences, the typical INM cases will have data that BaseOps cannot import. Using BaseOps' "Import INM Case" feature should be viewed as merely the first step in converting an INM case into a BaseOps case. You should carefully check all imported INM cases to insure that no differences were introduced by the importation process.
To import an INM case, follow these steps.
Choose Import INM Case from the File menu. The Import INM Case dialog box appears.
INM System Data File "prof_pts.dbf" - Type the full path name of the INM system file named prof_pts.dbf. 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 the file.
This file will be located in the sys_data subdirectory of the INM directory.
INM Case File "ops_calc.dbf" - Type the full path name of the INM case file named ops_calc.dbf. 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 the file.
This file will be located in the case directory of the INM case you wish to import. You may need to run the INM case to create this file. The case directory will be a subdirectory of an INM study directory.
Origin of INM Study Coordinates - Enter the origin of the coordinates used by the INM study that contains the case you are importing. You can find the origin by choosing Study from INM's Setup menu.
Press OK. BaseOps imports as much data as it can from the INM case.
Carefully check the imported case. BaseOps will attempt to issue warning messages describing any problems it finds while importing the case. However, it cannot automatically detect all problems, so you must check the imported case even if you receive no warning messages.
