Wasmer Consulting NMPlot
NMPlot is a Microsoft Windows application for viewing and editing sets of georeferenced data points. These data sets, also know as grids, represent measurable quantities that vary with geographic location. Examples include predicted noise levels around an airport, monthly records of rainfall across a state, and water temperature measurements in a lake.
NMPlot can produce contour and color gradient plots, apply mathematical transformations to grids, combine two grids, and interface with GIS systems.
NMPlot reads and writes NMGF files. NMGF is a standard file format used to store grids. Information about the NMGF format is available on the NMGF home page.
The development of NMPlot was sponsored by the United States Air Force (USAF) and the United States Federal Aviation Administration (US FAA) to produce contour plots for their airport noise models. More recently, it has been incorporated into other third-party applications. NMPlot is currently shipped as the standard graphical analysis tool of:
BNoise2, the United States Army's application for modeling noise from artillery and explosive operations
INM, the US FAA's application for modeling noise around civilian airports
Noisemap, the USAF's application for modeling noise around military airports
ROUTEMAP, the USAF's aircraft training route noise model
SANCTE, the Swiss environmental agency's Swiss Aircraft Noise Calculation Test Environment
SARNAM, the United States Army's application for modeling noise from small arms firing ranges
SIPS, the United States Navy's model of noise from explosive operations
TNM, the United States Federal Highway Administration's traffic noise model
While NMPlot was originally designed to support noise models, it is neutral to any particular application domain. It can just as easily process data from other types of models (for example, air pollution models) or from sources other than computer models (for example, measured data).
NMPlot has the ability to:
ARC/INFO Shapefile (SHP)
AutoCAD Data Exchange Format (DXF)
To use NMPlot with your data, it will be necessary to translate the data into the NMGF format, which NMPlot can read. Information on how to do so, including a quick-start guide, is available on the NMGF home page.
To display your data with a minimum amount of effort, follow these steps.
Create a NMGF file containing your data as described on the NMGF Quick-Start web page.
Start NMPlot, select Open from the File menu, and read the NMGF file.
Select Create Plot of This Grid from the Grid menu to create a contour plot of the data.
