[OSM-talk] Recent (last few weeks) T at H render changes

[Alex Mauer]

I've been looking at some of the recent changes to rendering of T at H, and 
have some comments.

Looking at the US at zoom 4 shows 3 distinctly  rendered zones:
East, Southwest, and Northwest.  Looking a bit closer, it seems like the 
east is further subdivided into northeast and southeast.

Of these, it seems that the southwest is the oldest (zoom 8 tiles last 
rendered in January), then the northwest and southeast (zoom 8 tiles 
rendered in early March), and finally the east (zoom 8 tiles rendered in 
the last week or so.

I have the following observations:

1. rail is overemphasized in the oldest zone, but completely absent in 
the newer ones.  This is unfortunate.

2.  State borders are missing or absent in all but the oldest.

3. secondary roads are overemphasized in the newest zone.  It makes 
whole areas into orange blobs. 
(http://a.tah.openstreetmap.org/Tiles/tile/6/17/24.png for example) 
They were about right in the middle-aged one.

4. primary roads are underemphasized in the middle-aged zones, but about 
right in the newest zone.

What do others think?
