I may be a 'johnny come lately'
Here are a couple of my earliest maps.
My first maps were in 1989 using ArcInfo to determine optimum monitoring locations based on source locations, prevailing meteorology and dispersion modeling, and schools, population centers, etc. None of these maps are with me now.
The earliest shown here (1992, I would have been 31) depicts results of a saturation monitoring study for fine particulate in and around Ashland, KY - site of much heavy industry.
The wind rose shows results from 3 different meteorological stations we set up for the study (on the Ohio and big sandy rivers, and on a ridge. These were daily averages. The contours are particulate concentrations 'kriged' from the 30 odd monitoring sites. The maps were produced in Axum statistical graphics software - and were set up for basically, '1 click' daily updates. I did early versions of these maps in Lotus 123!
We had the filters analysed, and the biggest contribution to particulate pollution in that heavily industrialized area was from unpaved roads and domestic barrel trash burning. The industries had pretty good pollution control - at least for particulate.
The second, shows results from a verification test of a method to measure emissions from large, diffuse area sources (such as wastewater treatment plans, surface coal mines, refinery complexes, etc.) using open path FTIR measurements, tracer gas releases (SF6), on site meteorology, and dispersion modelling. The cool thing about these maps is that they could be and were generated 'on the fly' from real time monitoring data. The whole thing was set up using Surfer and their GS basic scripting language. It worked well. This was one of my first contracts after going into business on my own.
During that time, I was also doing a lot of field survey work to locate monitoring sites and to determine monitoring configurations for the diffuse sources. I had always loved maps, but this was my introduction to making them. It wasn't long after that I could no longer risk the urge to try doing it for a living.
I still do some air quality measurement related work, but no maps in that line at present. I'm the (contract) quality assurance manager for a third party independent verifcation testing organization (Southern Research Institute) - but my 'day job' is maps.
