Why do I see a circular coverage distribution chart when I view others’ data but not when I view my own? I thought maybe it was because I joined recently, but since then I’ve noticed the circular coverage distribution chart for people joining after I did.
Since the observer location keeps drifting, I’m also wondering if the chart is based on the drifting position or on the real position.
I read in another post that this chart shows up when you reach 25000 positions reported. So a receiver with many positions received will start showing up faster than one receiver from a “sparser” sky. Mine showed up in a day.
I’m over 25,000 positions now. Maybe it will show up the next full day (so after midnight UTC)?
The site I thought was younger than mibe may be older. I was looking only at month and day. Looks like it’s been operational since Nov. 2013. I didn’t realize the program had been around that long.
I wish the coverage distribution pie (and collection data, for that matter) would be archived so we could see more than the current day (or week, collection data). Any plans to do this?
Ok I add the following wish under the christmas tree :
An animated coverage distribution to be able to see how distribution evolves across days of the week, hours of the day, day of the month, month of the year…
The colors are just determined by the number of positions. Each block on the chart represents a certain distance range (e.g., 150-200nm) within a certain direction (e.g., SW). If you hover over a specific block on the chart, a pop-up will tell you how many positions were seen in that distance range in that direction.
The color of the block is determined by this number, with the color trending towards a dark red to indicate the regions of heaviest activity and a very light blue to indicate regions of the least activity.
I have looked at this and have checked my SW position at 100-150 miles and have 40-50% more positions than others in my area however the colour chart is completely different.
Are there other factors ?
Here are screen shots of my PP and two others nearby.
Both of these feeders have similar positions reported (granted 25% of mine S at <50nm) however the remainder should produce different colour schemes. I am PP1 in the above URLs. You can see different colour schemes for the SW position with 3218(PP1), 2314(PP2) and 2431(PP3) positions respectively.
