Idee: diffusiekaart

Rob · Post by **Rob** » Thu Sep 04, 2003 1:37 am

Is het geen idee om de diffusie van ingegeven biljetten of gebruikers in kaartvorm te laten zien?

Verdeel de kaart van de EMU in een x aantal pixels en bepaal de kleur aan de hand van het aantal ingegeven biljetten of daar woonachtige gebrukers (wel zijn de achtergrondkleuren van land en zee gewoon aanwezig als basis; die worden vervangen wanneer er een user vanuit die pixel een biljet heeft ingegeven).

Natuurlijk moet de schaal logaritmisch zijn om écht de moeite waard te zijn, maar die kan beter door de statistici zelf worden bepaald.

You can understand dutch!!

And this is even more strange!

I quote you, and my post is in front of your post!

My apologies for posting my Dutch request in this English forum. I couldn't delete my message afterwards (being a guest and all).

Anyways: great that you're implementing this! I'm looking forward to it

red = most users or bills
green = something in between
blue = just a few users or bills

As a clarification, the scale has been tuned so that the maximum value will always be that same shade of red. It is very unlikely that the map would some day start showing mostly red, as there will always be areas that will have more users or notes than the other areas. A more reasonable goal would be that there would be more places covered with blueish/greenish dots.

At the moment the brightest red equals 700 users, the average green equals 30 users and blue equals less than 5 users. The numbers for the bill map are currently 35000 for red, 150-250 for green and less than 10 for blue.

I've now added the scale to the picture. The scale is likely to change slightly every night when the image is regenerated.

OK, I'll stop tweaking the new map soon

but I've changed the grid size a bit so that the blocks are bigger and thus cover a bigger area than before. This had to be done because some of the southern European cities were shown as just one or two pixels and it was a bit difficult to determine what colour the block really was. The reason why the blocks appear taller in north than in south is because the map uses Mercator projection which stretches the northern areas somewhat. In real life, all the blocks are actually the same size, it just shows the sizes differently on the map.

The map now also shows land and sea areas in different colours.
