This is sort of an AD to see if anybody is interested in noise modelling and could use some tools that I have developed, but is more of a broadcast to see if anybody may be working in this obscure area and need a hand. I have recently developed some tools to intgrate Mapinfo with the FAA's Integrated Noise Model. At present they are mainly hack tools specific to the airports that they were developed for (Adelaide, Coolangatta and Parafield), but there is a basis for easy adaption to other locations. Is anyone interested? The tools include: Generation of the binary 3CD file around the airport from a terrain model in MapInfo, even if it exists somewhere else in the world other than the US (strangely enough, this matters). Calculation of the x and y distances from a reference point for runway ends or naviagation points Generation of flight paths in real world coordinates from the trk_segs.dbf database in INM, without going through DXF and retaining the flight path identifier in the database Generation of the noise contours in real-world coordinates from the contours.dbf in INM so that you can overlay them onto other data. These were all bundled with an Access program that created INM input files from numbers of aircraft going to different destinations, runway usage for different categories of aircraft, night-time/ daytime usage and rules for flight path allocation based on destination. The program also automatically ran the INM model and then generated the contours after the modfel was run and produced a bitmap of the result. At one stage, we even had it working over the web so that you could input your data and run the model on our server over the web, but sometimes you can try to be just too tricky for your own good. Anyway, Is anybody interested in these sorts of tools? I am not really in the industry and chances are they will not further developed unless htere is some interest elsewhere. I now know more about airports and flight paths used etc. than any soil scientist should. Perhaps it could be put to use somewhere else (preferably at an airport near some ski fields?). Robert.
