I have recently purchased some AI 8.0.2 products and ArcIMS and also have
MapInfo and ArcView. A co-worker and myself are very interested in finding
information about RF Analysis programs. We do a lot of mapping of VHF
coverages for many airline customers who are interested in what we have at
various altitudes, say between 5 K and 30 K Feet at Mean Sea Level. There
are times when we don't have the data and have to process new stations and
the only way to do it is by having my coworker use TAP (Terrain Analysis
Program), which runs in DOS, to create text files of real RF coverage. This
program runs a series of batch files created by scratch and based on the
topography, creates a comma-delimited text file that contains 361 lines of
values. The first line shows the header or field information and the rest
gives the x,y coordinate of where the edge of the coverage goes. So, the
program looks at 360 radial points all around the station antenna. The
elevation data the program uses in its algorithms is proprietary and am not
sure how accurate it is. I probably don't have much faith in it since I
can't look at it. The program takes into account the height and kind of
antenna, altitude (at Mean Sea level), location and various other parameters
associated with RF. TAP can run batch files of many locations at once, its
kind of slow, but it works.
We are looking for more efficient solutions including other types of
software that can run in ArcInfo 8.1 or ArcView 8.1 that can produce polygon
or polyline data that represents RF coverage of an individual station at a
specific height in MSL. This program should also be able to run batch
processes. I have heard about Decibel Planner, a MapInfo Tool, but I would
assume that the functionality is possible in ArcView or ArcInfo.
If anyone has any ideas and can provide me with a contact list of companies
or people that use ArcView and/or ArcInfo for RF analysis projects, I would
greatly appreciate it.
Thanks and Will Sum,
