I love playing with maps. I will attempt to share what I learn and the new things that I am doing with GIS systems

As I stated last week, ALOHA is out and I am hand coding the algorithms for isolation zones.
The information will be coming from the Emergency Response Guide which provides an initial radius for isolation and an extended distance downwind.
I have succeeded in creating the 2D plot mathematically. The developement page was written in Classic ASP, and the coding changed the CSS for plotting 36 images (1 dot for every 10*) in a semi-circle upwind from the (fixed) source, and an ellipse downwind. It is very crude in this rendition, but once we port that over to writing javascript and putting it into VE it should be pretty good.
Give me a day or so, and I should have a static version online.
I already have the next project in the back of my head- this will be scripting to convert USNG (or MGRS) grid coordinates to my emergency mapping systems
