Hi All, I am using semi-transparent markers to approximate a heatmap which is also clickable. I have a 25x25 pixel marker which I'd like to expand upon zooming down each level. I can do a hit and miss to find out what the proportional difference would be with each zoom level, but I wondered whether anyone has done this before?
Basically I want the roughly same area of land coverage for my 25x25 circle when I zoom down. I'll likely have it restricted to from a state to city level of zoom so I don't need to worry about really close zooms. I haven't tried it yet, but I likely will start with a 100x100 sized marker which is compressed at the state level and then passed through its defined size to be expanded at the lowest level. This will hopefully avoid my circle turning into too much of a squarish shaped blob if people know what I mean. Any thoughts or link directions on this would be appreciated. I'll share what I call my "Rough clickable heat map method" once its become a little less clunky. I wish I could find a method to use multiple colours at the interection of the semi-transparent markers. I may try some sort of overlayed coloured polygons, if I can figure out how to calculate the concentrations in some quick and meaningful way. I need to change variables and redisplay the data fairly quickly so I need to avoid a lot of math crunching.
