website: per-cell outline could convey much more information
On radiocells.org, each cell is a marker, and clicking it shows a polygon which is the bounding box of observations. It would be far more useful to show a dot for each observation, and to color code them as follows, with signal strengths >= the first value using the given color.
- -60 purple
- -70 blue
- -80 green
- -90 yellow
- -100 orange
- -110 red
- other dark red
Additionally, it would be really nice to be able to close this by clicking again, and to have opening some other cell to close the others.
That's definitely on the never-ending todo list ;-)
Behind the scenes, we're already saving the cell strenght for each point within the polygons. Technically we store x/y coordinates and store the cell strength in z-dimension ('height above ground')
What we currently lack is a proper visualization technique. As this is sort of a heatmap topic, I was considering https://github.com/Leaflet/Leaflet.heat (see their demos)
Also, it would really help if the cell markers themselves had some sort of indication of number of measurements. A marker with 2 measurements is useful for knowing that a cell exists, but it's not that useful for locating it (on a map view; it still helps for rough geolocation).
