I love playing with maps. I will attempt to share what I learn and the new things that I am doing with GIS systems
Never mind my calculus, geometry, and trigonomentry teachers are bashing heads on who taught me all of the tricks that I used to do it.
What we have here is a heavily updated version of that blue blob from last week. I am using the same base map with the same spy satellite crashing into Downtown Milwaukee
What I need to do is to get the equations
It seems like what I have been doing is a parallel to a demo blogged by VE for Government
I left a comment on that blog entry and at their VE 4 Government blog on Spaces.
I was replied with
Glad to hear. Do you think you could bring volume to the plume so that when viewed in 3D, the user can ascertain the height of the dispersion?
Dying to see someone really do something like this with plumes or flood waters in 3D!
And I think I am
I've been doing some tweaking of my mapplication.
The ancient Aloha NOAA dll would render an threat zone and a confidence zone. The difference between the 2 is that the confidence zone swept out a wider arc- compensating for variations in wind direction and other inaccuracies. Never can be too safe with the hazardous materials
I created a new algorithm for my mapplication, to add in that confidence area besides the original threat zone. I based mine off of the Emergency Response
So now I have a map which is hard coded on the release location. A simple point-click should be able to take care of that portion. Then the next part will be a db lookup to get the isolation distances. When we are done it should be a 3 part
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
